Should reparent remove the window from the X save set if the id to reparent into is "root"?

It seems some WM have issues with playback.tcl script termination.

X_MapWindow is causing a BadMatch error in demo.tcl.

3.6.12 - Sat Mar 29, 2008

I added a build.conf.ubuntu.

I updated TkXext.record.c to use volatile sig_atomic_t with the signal handler doExit for safety and correctness.

3.6.11 - Tue Jun 6, 2006

I updated the build.SunOS.conf with an APP_CFLAGS example for the Sun C compiler.

I removed TkXext.make.window.exist from the TUTORIAL and demo.tcl.  [winfo id] does its job for the cases in the TUTORIAL and the demo.

The demo is going to need some more work in the future.  I noticed today that the xterm doesn't resize properly.

I updated the LICENSE with the year 2006.

3.6.10 - Fri Jun 2, 2006 

I have added support for SunOS/Solaris thanks to Nick Matthews.

I have changed all build configuration files and tickmakefile, so that LD_RPATH is no longer hardcoded to use -rpath with ld.  Apparently that is a GNU convention.

3.6.9 - Tue Apr 11, 2006

I added TkXext.delete.or.kill for sending the WM_DELETE_WINDOW message if the client supports it, or calling XKillClient if it doesn't.

I made TkXext use Tk's X error handler.

I cleaned up and improved the window find.c code.  It now finds windows properly in Whim always.  I also tested it in TWM.

I improved the embed_firefox.tcl example a great deal.

I upgraded the version number in all 3 places.  We need a better mechanism for doing this I think.

3.6.8 - Mon Apr 10, 2006

I added "root" string handling to TkXext_StringToWindow.  Now all of the
TkXext commands understand root.

I fixed a minor bug (proactively) that I noticed in init.c. 

- Tcl_InitStubs (interp, TCL_VERSION, 0);
+ if (NULL == Tcl_InitStubs (interp, TCL_VERSION, 0))
+  return TCL_ERROR;

and so on.  Tcl_InitStubs turns into a Tk_PkgRequire when -USE_TCL_STUBS is
not present during a build.  Tk is similar in this regard.

I fixed a tickmakefile bug that resulted in TkXext.so always building.  
The solution was to use concat rather than list.

I fixed the pkgIndex.tcl version for the more pedantic 8.5a4 package mechanism.

I updated the package revision in the build.conf and build.conf8.5 examples.

3.6.7 - Thu Mar 24, 2006

I added a demo script for embedding Firefox or any window with Google* in its
wm title.   Steve Landers tested 3.6.6 in Linux, and inspired the demo script.

I tested in 8.4 for the first time in a long time.  

TkXext works fine with 8.4 or 8.5.

3.6.6 - Thu Jan 26 10:35:30 MST 2006

I removed some old files that are no longer used.  

I fixed a typo in the TkXext.unmap.window's OBJ_CMD creation.  

I removed -Wl,-rpath that could cause a build failure for some people that don't
use the GNU toolchain.  The build.conf already has the necessary options to
replace this.

I made the isxdigit() test in TkXext_StringToWindow use an int, rather than 
subscripting a char *.  This may fix a bug.

EXT_VERSION in the default build.conf was updated to 3.6.6.

3.6.5 - Fri Nov  4 14:25:08 MST 2005

I added information in the README about how to load the "record" extension into 
an X server.

A SIGINT handler was added based on some feedback from mmc.  Now Ctrl-c should 
not break an output script.

I added error checking for XGetWMNormalHints as part of an audit.  I sure have 
learned a lot over the years...

I added error checking for XKeysymToKeycode in TkXext_SendKeyPress, and 
TkXext_SendKeyRelease.  sscanf usage was changed to Tcl_GetLongFromObj (cast to 
(long *)).  We now use a separate variable and assign the "unsigned long" value 
to the KeySym.  This may prevent problems in the future if the sizeof a KeySym 
changes or isn't the same as in XFree86.


3.6.4 - Wed Nov  2 18:40:05 MST 2005

XTestGrabControl is now used in init.c, so that TkXext playback scripts work 
properly when they cause a grab indirectly.

The following were adding:
build.tcl
build.conf
tickmakefile

I removed the old build systems, because they were too painful to maintain, and 
I think tickmake is better.  This fixes a missing -DUSE_TCL_STUBS and 
-DUSE_TK_STUBS.

I removed the #ifdefs for stubs too.


3.6.2 - Thu Jul 21 02:38:24 MDT 2005

I fixed a memory leak in TkXext.record.c.  XRecordFreeData is now used to free 
the event for reuse.

I fixed a potential bug in find.c and cleaned up the code a bit.


3.6 - Sun Oct 19 02:15:00 GMT 2003

I have added TkXext.focus code and refactored several files.  There is an X 
error that seems to occur sometimes initially.  I suspect a race condition 
between xterm and TkXext.  This doesn't seem to cause any bugs, but it could 
potentially.

3.5.1-WIP-1 - Thu Oct 2 01:58:48 2003

I fixed some simple memory leaks that occured because I didn't add 
Tcl_DecrRefCount calls.  This should all be fixed now.  I updated the README to 
have the proper information about what is needed and how it works.  I added 
quite a bit to the TUTORIAL, and it now covers 3 topics.  I added tickmake-7 and 
I have started building default.mk

3.5 - Thu Sep 4 14:32:53 MDT 2003

 I fixed the configure script to compile and link properly in NetBSD.  I created 
the TUTORIAL, and added to the PLAN.  It now builds and runs properly in NetBSD 
without any problems.

3.4 WIP 6 - ~Fri Jun 13 00:50:21 GMT 2003
	TOO MANY CHANGES TO LIST

3.0 - Wed May 7 19:49:04 GMT 2003

	Almost the entire project has been rewritten.

	TODO: make sending work.  See if there is a
	pattern between iso-8859-1 chars and X KeySyms.


2.1.5 - Wed Jan 2 17:21:44 MST 2002

TkXext
	I replaced the calls to strcmp with strncmp for
	security reasons.  I removed the ifStrMatch macro.
	I replaced calls to var++ with ++var (I'm still
	learning).

	The test.tcl had the same change as erxvt.

erxvt
	The long trick to find the latest wish was changed.

2.1.4 - Mon Oct 15 19:50:19 MDT 2001

TkXext
	The embed command was improved to fix problems with embedding
	into the root window.

	The findWindowViaTitle was improved to use a better method
	of handling timeouts.

	sendEvent is now sendString, and the C function calls/name
	use that name now too.

	automatedTests.tcl now passes all tests in Panache, because
	of the changes I made.

erxvt
	(1) If the session was not embedded properly, click the empty
	window to re-embed it.

	(2) Changed [info procs embed] to [info commands embed] to
        avoid loading the extension twice.

2.1.3 - Thu Sep 20 17:11:58 MDT 2001

	This release has build changes and now you can run make install.
	So, you can now use 'package require TkXext' in your scripts instead
	of using load.  The test.tcl and erxvt I decided should continue
	to use load because I want new users to be able to try it out
	without installing the package.  Perhaps I could test for the
	package and if it isn't there do load.  --prefix is an option
	in the configure script.  I updated the README with info
	about package require TkXext and the new build option.

	Thanks to Dave for more erxvt changes.

erxvt:  Logging out a session (e.g. through Ctrl/D), automatically
	switches to the button on the right, instead of arbitrarily
	picking the first one.


2.1.2 - Wed Sep 12 17:04:58 MDT 2001

	I've removed DoesWindowExist.  I renamed the functions that
	are called by Tcl commands, so that they now use a lower case
	beginning letter.  I fixed a bug in embed being called	with
	0 arguments, which was pointed out by EE.  I added a timeout
	to findWindowViaTitle that waits until 10 user seconds have
	passed while searching for the window until returning None.
	Various functions were updated to return TCL_ERROR when None
	is returned from findWindowViaTitle, and I added error 
	messages too.
	
	Todo: The SendButtonPress command needs to be	extended, so 
		that it supports sending -to .path or -to root.
	
	erxvt	Changes:
		title dialog not transient first time; call wm transient *before*
		tkwait visibility, and remove from Erxvt:Switch.

2.1.1 - Sat Sep  8 03:39:44 MDT 2001
	
	I've saved a few lines of code with a macro named CMD_ARGS.
	It basically saves me from reading and typing out the standard
	Obj command arguments.  I also did the same in the command 
	creation section of main, with the macro OBJ_CMD.  I added
	an ifStrMatch macro to cleanup some of the code.  The end
	result of all these macro additions is more readable and
	concise code 675 LOC vs. 700.
	
 	Erxvt changes for the previous release:

        - Avoid the 3000K+ memory overhead associated with a wish
          process, by getting an already running erxvt to spawn a
          window for us.
        - Make the 'Set Title' dialog box transient for the current
          frame, so it doesn't get buried underneath the main window
          (auto-raising windows).
        - Fix various problems associated with a session being logged
          out while changing the title (that is, the modal dialog box
          cannot prevent you from using the current session -or logging
          it out- because the rxvt session is a separate application,
          so it falls outside the grab).
        - Resource: Erxvt*geometry. Format <width>x<height> in pixels.
        - Resource: Erxvt*emulator. Format [rxvt|xterm].
        - Remove the 'rxvt -geometry' hack.
        - Remove the 'rxvt -fn ofCourseYouCant' hack.
        - Keep track of the currently active session for better task
          management.
        - Insert formfeeds, for 'paging around'.

	
2.1 - Sat Sep  1 20:41:36 MDT 2001
	
George
	This release made changes to embed (formerly embed2) and erxvt.  
	I've removed embedId and the old embed, and replaced embed2 as embed. 
	Dave sent me a bunch of changes to embed2, and a new erxvt.  I've
	modified his code slightly to fit my style, and added one more error
	check.  A new automatedTest.tcl file has been added by me, and it works 
	well, as long as make debug isn't used to build the library.  I'm
	not sure what changes were made to erxvt but it works well.

	Please view automatedTest.tcl and tell me if you find anything that
	may be problematic.  I want to enhance it to test other command as
	well, but that will have to wait until I add more error checking to
	other commands.
	
	Todo: I should probably write a script to automate building with
	Tcl/Tk 8.0.5 because I have to manually build and test for both
	8.0.5 and 8.3.3
	
	Thanks to Dave for this release.
		
Dave
	Additional error checking (for missing arguments to options, etc.). 
	The malloc-and-copy seems unnecessary; in any case, the data wasn't 
	being freed.  Removed Tcl_AppendResult where Tcl_SetResult will do. 
	If the window is reparented out to root, don't store the id in the 
	hash table (although I should probably remove the hash table entry 
	at that point, as well as when the window is destroyed). This assumes
	of course that there will only be one embedded window in a widget 
	(I haven't tried, but I'd imagine they might start fighting with 
	each other). The empty #define for dout needs the parameters. 
	I've added some comments, nasty habit...

		
2.0.10 - Fri Aug 31 00:06:33 MDT 2001

George
	I added hash table handling to embed2.  embed2 is now used
	in test.tcl  Dave sent me a great screenshot of Erxvt using 
	TkXext, which will now appear on the TkXext home page.  I 
	really	like Dave's new stretchWindow	command (see below under Dave).
	It solves a problem I wasn't sure how to go about fixing. 
	I've used the stretchWindow command in test.tcl too.  I 
	updated the README. 

	I would like people to test the embed2 command, because eventually
	I want to replace embed and embedId with it, and then rename it to 
	embed.  I'm also thinking about	renaming sendEvent to sendString.
	Maybe while I'm at it I will make sendEvent able to send almost
	any kind of event.

	I'm thinking about implementing a new focus command, or possibly an
	overloaded Tk focus command, that would allow changing the input
	focus to an embedded window.

	Lots of thanks to David Wijnants for this release.

Dave
	- New procedure: stretchWindow. Stretches or shrinks an
	  embedded window to fit inside its parent.
	- sendKeyPress: check hash before anything else, see next.
	- sendKeyPress: possibly remove all but final syncs.
	- Erxvt is now resizable.
	- Erxvt starts up centered on the display, rather than at the
	  default location (i.e. random, probably half off-screen).

	- Erxvt now seems to work fine on FreeBSD and Red Hat 6.2
	  (xfwm, mwm and kde on both platforms), except for still 
	  occasional reparenting glitches - about 2/50 ?
	- Missing scrollbar problem under Red Hat seems to have 
	  sorted itself out - as a side-effect of resizing.



2.0.9 - Wed Aug 29 22:54:35 MDT 2001
	
George
	I added a dout macro to cleanup #ifdef DEBUG for fprintf (stderr, ...) 
	I changed around the code to use Tcl_AppendResult instead of
	using snprintf with a string and Tcl_SetResult.
	
	I'm not sure why rxvt loses the scrollbar at times.  I think it's a
	bug in rxvt.  It can be worked around by pressing shift-up or
	shift-down to scroll the rxvt window.

	I think that Dave's Erxvt is coming along nicely, see the changes below.
		
		
Dave
	Lots of improvements to erxvt :

	- Better process/window housekeeping.
	- Cleanup when a session is exited.
	- Removed 'grimreaper', cleanup zombie when session exits.
	- Added a 'new' button - for creating new sessions.
	- Show session title on title bar and sticky-in buttons.
	- Change session titles by right-clicking the session's button.
	- Support multiple windows and instances.
	- Prefix all procedures (should use namespace really).

	TkXext.c :

	- FindWindowViaTitle: free QueryTree children.
	- Embed: cleaned up 'hashptr' local block/variables (cf. EE).
	- Embed: error if .new_parent doesn't exist (EE).
	- SendKeyPress: additional error checking.

	Still to do :

	- Erxvt: now works fine on FreeBSD 4.2 and Red Hat 7.1, but why
	  does the scrollbar nearly always disappear on Red Hat 6.2 ?
	- Send window resize messages.


2.0.8
	This release features a new command called embed2, which may eventually
	replace the current embed and embedId commands.  It works like this:
	embed2 -name "My Title" -into .f  or  embed2 -id 0x123456 -into .f
	
	It works well on my system.  It has a lot of error checking relative
	to the other commands.  Now I just need people to test it and tell me
	how well it works.
	
2.0.7
	EE sent me a bug fix for WM_STATE handling, and added debugging messages.
	I changed configure to output -DDEBUG to the makefile for the debug
	target.
	EE also added XAddToSaveSet() for the embedded window.
	EE cleaned up some of the blocks that I put within the embed functions,
	because he found them annoying, and they probably decrease the clarity.
	A few minor changes to the names of things.


	Added a space2tab.tcl script (not useful to users)

	I really need to do more error checking in future releases, as EE pointed
	out.


2.0.6
  This release has great bug fixes and improvements from
  David Wijnants and EE.

  Dave was kind enough to provide a log of his changes.

	- *BUGFIX* isupper() returns nonzero for uppercase chars, so I've
  removed the '== 1' - this caused SendEvent to incorrectly send 
  commands in all lowercase.
  [GPS This bug was due to my ignorance of isupper.]

	- Wrinkle: replaced the hard-coded specialCharsSize definition with a
  more general expression, to make adding elements to the specialChars 
  array if necessary a little easier.
  [GPS This was a great idea.]

	- New: added an error handler because I still get random X errors.
  These seem to be mostly harmless, but the default action (being
  killed !) is a bit harsh, because it doesn't give me any chance to 
  clean up my invisible rxvts. 
  [GPS I've renamed his error handler to TkXextErrorHandler] 

	- *BUG* FindWindowViaTitle can loop indefinitely when sending events
  to a window that has been reparented (embedded). I think this is
  because different window managers reparent windows in different ways,
  so the one we're trying to find might be two or three levels down
  the query tree. I experience his problem when using vim in an rxvt
  session embedded in a Tk widget in xfwm under FreeBSD 4.2, but I've 
  avoided the problem in the new SendKeyPress procedure. The existing
  SendEvent and SendButtonPress procedures might also be affected.

  - New: added a SendKeyPress procedure that handles non-alphanumeric
  keypresses. The keycode is the value given by the %k substitution
  in Tk, but the shift state has to be handed explicitly (see the bind
  commands in the erxvt script).
  
  bind .f$n <Shift-KeyPress> "sendKeyPress .f$n Shift %k ; break"
  bind .f$n <Control-KeyPress> "sendKeyPress .f$n Control %k ; break"
  bind .f$n <KeyPress> "sendKeyPress .f$n {} %k ; break"

  [GPS Dave allowed me to include his erxvt script with the TkXext
  distribution.]

  I received some bug fixes from EE.  He solved a problem with some
  window managers.  I've modified his code slightly to accomodate my
  window manager, which doesn't set the state as soon as others.  I'm
  hoping it will still work on his system with an old Enlightenment 
  WM.  I was tired when I worked on it, so maybe tomorrow it won't
  look as good.
 
  I increased the version from 2.0.2 to 2.0.6 in the package provide
  command, which is something I should have been doing in previous 
  releases.	

2.0.5
	This release should fix the embed twice problem.  You can now
	use string match type of characters for title matching.  This way
	you can do something like embed "Netscape*Google*" .win

	from:	if (titleFound && strcmp (titleFound, titleToFind) == 0) 
	to: if (titleFound && Tcl_StringMatch (titleFound, titleToFind) == 1) 

	from: XReparentWindow (dis, win, newParent, 1, 1);
	to:	/*workaround buggy window managers*/
		for (i = 0; i < 3; i++) {
		XReparentWindow (dis, win, newParent, 1, 1);
		}


	added to file test.tcl:	
		#You can also use string match type of characters
		#embed "Netscape*Teoma*Search" .t.f


2.0.4
	LICENSE file added, and license changed to BSD style

2.0.3
	changed: if (doesWindowExist (dis, parent, win, 0) == 1) {			
	to: if (doesWindowExist (dis, children[i], win) == 1) 
	performance++.
			
2.0.2
	embedId 0xc00002 .  finally works
	I removed the root window call and variable from doesWindowExist, 
	because it isn't needed anymore.
	
	
2.0.1
	This release features bug fixes by EE.
	
	Changes to doesWindowExist
 	if (win == parent) {
		return 1;
	}
	children[i] == win was changed to	doesWindowExist (dis, children[i], win)
	
	New command embedId.
	
	configure now builds a Makefile with a debug target that provides
	-ansi -Wall -pedantic and -pedantic-errors.

.NOEXPORT:

Refactor the SendKeyPress and SendKeyRelease functions.  They could easily be the same routine I think.

Add checks via auto_execok to see if xedit is installed.  Also use other applications to test TkXext, such as Mozilla.  We need to make sure that everything works as well as possible.
-- older ---

Rewrite the demos and possibly fix erxvt.  The demos should not just use xterm.  I should use common programs like xedit, xmag, and so on to give the user an idea of how well TkXext works.
			
Don't forget to test in KDE, because it had some issues with reparenting which may be fixed now.

This document applies to the 3.4.1, 3.5.1, and 3.6.5 releases of TkXext.  It may 
work with future releases as well.

TkXext is a Tcl/Tk extension that provides the ability to:

 o find desktop windows via a titlename

 o embed desktop windows into Tk frames or toplevels

 o record events and play them back

 o send strings to windows
 
 o resize embedded windows or other windows for which you have an id 


This tutorial will teach you how to record events, playback events, find 
windows, and reparent/embed windows into Tk frames.


-- Record/Playback Events -- 

When you compiled TkXext a shared library and an executable should have been 
built.  TkXext.record.bin is used to record events that occur on the X server.  
You can redirect it to a script like so:

 ./TkXext.record.bin > script

To stop recording press the Pause/Break key or type Ctrl-c.

You can view the script with a text editor.  

Now let's try to playback the script.  First we have to have a little script 
that evalutes it.  TkXext comes with a playback.tcl script which you can use 
like so:

 wish8.4 playback.tcl script


It's often desirable to use a pattern like:
 sleep 4 ; echo CHEESE ; ./TkXext.record.bin > script

If you're testing in Xnest you may also find it useful to do a similar pattern 
before you have activated the Xnest window.

-- Finding a Window --

Each toplevel window in X has a window id.  We can use the window id to embed an 
application into another application, or resize/move it.

For example:
package require TkXext

set id [TkXext.find.window "FOO BAR"]

If TkXext is unable to find the window named "FOO BAR" id will have the value 0.


-- Reparenting/Embedding a Window --

Now we shall demonstrate how to reparent/embed the id into a Tk window:

package require TkXext

proc main {} {
 set id [TkXext.find.window "FOO BAR"]
 if {0 == $id} return

 pack [frame .f] -fill both -expand 1

 TkXext.reparent.window $id [winfo id .f]
}
main

We should now have the application with the window title of "FOO BAR" reparented 
into our Tk frame .f

If we resize .f you will find that our $id window doesn't grow.  We can fix this 
by binding .f to <Configure> and adding a proc that calls TkXext.resize.window 
$id $width $height.


By now you should know how to record events, playback events, find windows via 
the title, and reparent or embed windows into Tk frames.

For further information please read the demo.tcl code.

# erxvt - embedded rxvt
#
# This script is provided, free of charge, under the same conditions
# as the TkXext extension it comes with; see the file LICENCE for 
# details.
#
# Here are some ways of using the script :
#
# - just run it at the command prompt to get one session.
# - run it with a parameter to prestart -that many- sessions.
# - source it from a Tcl procedure, and call Erxvt:Launch whenever.
# - use the Tk send command to call Erxvt:Launch from somewhere else.

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Added "-DNDEBUG" to CFLAGS_DEFAULT
	when building with --disable-symbols.

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: [Bug 3555058]: Checkin [30736d63f0] broke
	CFLAGS_DEFAULT, LDFLAGS_DEFAULT

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: [Bug 3511806]: Checkin [30736d63f0] broke CFLAGS

2012-08-07  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Bug 3511806]: Checkin [30736d63f0] broke CFLAGS

2012-07-25  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: My previous commit (2012-04-03) broke the ActiveTcl
	build for AMD64, because of the quotes in "C:/<path>/AMD64/cl.exe".
	It turns out that the AC_TRY_COMPILE macro cannot handle that.

2012-07-22  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Tidy: consistency, spelling, phrasing, whitespace.
	No functional change.

2012-04-03  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Bug 3511806] Compiler checks too early
	This change allows to build the cygwin and mingw32 ports of
	Tcl/Tk extensions to build out-of-the-box using a native or
	cross-compiler, e.g. on Cygwin, Linux or Darwin.

2011-04-02  Jan Nijtmans  <nijtmans@users.sf.net>

	* install-sh: Fix issue with library stripping in install-sh
	 (backported from kevin_walzer's patch from Tcl 8.6 trunk)

2011-04-05  Andreas Kupries  <andreask@activestate.com>

	* tcl.m4: Applied patch by Jeff Lawson. Nicer error message when
	  tclConfig.sh was not found.

2010-12-15  Stuart Cassoff  <stwo@users.sourceforge.net>

	* install-sh: Upgrade to newer install-sh and use it.
	* tcl.m4:

2010-12-14  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Better building on OpenBSD.

2010-12-14  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: when using gcc, don't try to determine Win64 SDK

2010-12-12  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: Determine correctly a cross-compiler-windres

2010-11-23  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: add some cross-compile support, borrowed from Tcl 8.6

2010-09-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct HP-UX LDFLAGS (only used when building big shell)

2010-09-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add extra if check for .manifest file generation
	Add notice about package name and version being built.

2010-09-09  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [FREQ #3058486] TEA_LOAD_CONFIG doesn't set all BUILD_ vars
	Slightly related: defining BUILD_$1 on all platforms - not only win -
	allows the -fvisibility feature to be used in extensions as well, at
	least if you compile against tcl >= 8.5.

2010-08-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: ensure safe quoting for autoheader usage

2010-08-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add TEA_ADD_CLEANFILES macro to make adding cleanfiles
	easier, and add *.exp to CLEANFILES Windows default.
	(TEA_MAKE_LIB): Enhanced to check for MSVC that requires manifests
	and auto-embed it into proj DLL via MAKE_SHARED_LIB.  Also define
	VC_MANIFEST_EMBED_DLL and VC_MANIFEST_EMBED_EXE that do the same
	magic in case it is needed for extended TEA projects.

2010-08-16  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.9 ***
	If upgrading from TEA_VERSION 3.8, copy over tcl.m4, change
	TEA_INIT to use 3.9 and reconfigure (ac-2.59+).
	BUILD_${PACKAGE_NAME} will be auto-defined on Windows for
	correct setting of TCL_STORAGE_CLASS.
	TEA_LOAD_CONFIG users should remove the SHLIB_LD_LIBS setting done
	in configure.in (LIBS will be automagically populated by
	TEA_LOAD_CONFIG).
	TEA_EXPORT_CONFIG has been added for ${pkg}Config.sh creators
	SHLIB_LD_FLAGS was deprecated a while ago, remove it if it is
	still in your Makefile.in.

	* tcl.m4: add /usr/lib64 to set of auto-search dirs. [Bug 1230554]
	Auto-define BUILD_$PACKAGE_NAME so users don't need to.  This
	needs to correspond with $pkg.h define magic for TCL_STORAGE_CLASS.
	Auto-define CLEANFILES.  Users can expand it.
	(SHLIB_LD_LIBS): define to '${LIBS}' default and change it only if
	necessary.  Platforms not using this may simply not work or have
	very funky linkers.
	(TEA_LOAD_CONFIG): When loading config for another extension,
	auto-add stub libraries found with TEA_ADD_LIBS.  Eases
	configure.in for modules like itk and img::*.
	(TEA_EXPORT_CONFIG): Add standardized function for exporting a
	${pkg}Config.sh.  See use by img::* and itcl.

2010-08-12  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.8 ***
	If upgrading from TEA_VERSION 3.7, copy over tcl.m4, change
	TEA_INIT to use 3.8 and reconfigure (ac-2.59+).
	No other changes should be necessary.

	* tcl.m4: remove more vestigial bits from removed platforms.
	Add back SCO_SV-3.2*.
	Remove use of DL_LIBS and DL_OBJS and related baggage - these are

	* tcl.m4: sync with tdbc tcl.m4 changes
	(SunOS-5.11): Sun cc SHLIB_LD: use LDFLAGS_DEFAULT instead of LDFLAGS

2008-12-02  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.7 ***

	* tcl.m4: in private header check, check for <plat>Port.h instead
	of Int.h to ensure all private headers are available.

2008-11-04  Daniel Steffen  <das@users.sourceforge.net>

2008-02-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tcl.m4 (TEA_CONFIG_CFLAGS): Updated to work at least in part with
	more modern VC versions. Currently just made the linker flags more
	flexible; more work may be needed.

2007-10-26  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): add support for 64-bit X11.

2007-10-23  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Tagged tea-3-branch to start TEA 4 development on HEAD ***

2007-09-17  Joe English  <jenglish@users.sourceforge.net>

	to build shared libraries on current NetBSDs [Bug 1749251].

2007-09-15  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: 	replace all direct references to compiler by ${CC} to

	(SunOS-5.1x):	replace direct use of '/usr/ccs/bin/ld' in SHLIB_LD by
			'cc' compiler driver.

2007-08-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: check Ttk dir for Tk private headers (8.5).
	Add some comments to other bits.

2007-06-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: fix --with-tkinclude alignment. [Bug 1506111]

2007-06-06  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): fix 64bit arch removal in fat 32&64bit builds.

2007-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tcl.m4: Added quoting so that paths with spaces cause fewer
	problems.

2007-03-07  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): s/CFLAGS/CPPFLAGS/ in -mmacosx-version-min check.

2007-02-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_PRIVATE_TCL_HEADERS, TEA_PRIVATE_TK_HEADERS): check
	that the dirs actually have private headers. [Bug 1631922]

2007-02-04  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: add caching to -pipe check.

2007-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and
	move (rather than duplicate) -isysroot flags from CFLAGS to CPPFLAGS to
	avoid errors about multiple -isysroot flags from some older gcc builds.

2006-01-19  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: ensure CPPFLAGS env var is used when set. [Bug 1586861]
	(Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS when
	present in CFLAGS to avoid discrepancies between what headers configure
	sees during preprocessing tests and compiling tests.

2006-12-19  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): --enable-64bit: verify linking with 64bit -arch flag
	succeeds before enabling 64bit build.

2006-12-16  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Linux): fix previous change to use makefile variable
	LDFLAGS_DEFAULT instead of LDFLAGS in SHLIB_LD, to ensure linker
	flags in sampleextension Makefile are picked up.

2006-11-26  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Linux): --enable-64bit support. [Patch 1597389], [Bug 1230558]

2006-08-18  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for
	universal builds including x86_64 and for use of -mmacosx-version-min
	instead of MACOSX_DEPLOYMENT_TARGET. For Tk extensions, remove 64-bit
	arch flags from CFLAGS like in the Tk configure, as neither TkAqua nor
	TkX11 can be built for 64-bit at present.

2006-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: []-quote AC_DEFUN functions.
	(TEA_PATH_TKCONFIG): Fixed Windows-specific check for tkConfig.sh.
	(TEA_MAKE_LIB): Prepend 'lib' for Windows-gcc configs.

2006-03-07  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4: Set SHLIB_LD_FLAGS='${LIBS}' on NetBSD,
	as per the other *BSD variants [Bug 1334613].

2006-01-25  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA version 3.5 ***

	* tcl.m4: keep LD_SEARCH_FLAGS and CC_SEARCH_FLAGS synchronous
	with core tcl.m4 meaning.

2006-01-24  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): use makefile variable LDFLAGS_DEFAULT instead of
	LDFLAGS in SHLIB_LD, to ensure linker flags in sampleextension Makefile
	are picked up. [Bug 1403343]

2006-01-23  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add C:/Tcl/lib and C:/Progra~1/Tcl/lib dirs to check for
	*Config.sh on Windows. [Bug 1407544]

2006-01-23  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): for Tk extensions, remove -arch ppc64 from CFLAGS
	like in the Tk configure, as neither TkAqua nor TkX11 can be built for
	64bit at present (no 64bit GUI libraries).

2006-01-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: restore system=windows on Windows.
	Remove error if 'ar' isn't found (it may not be on Windows).
	Do not add -lxnet or define _XOPEN_SOURCE on HP-UX by default.
	Ensure the C|LDFLAGS_DEFAULT gets the fully sub'd value at
	configure time.

2006-01-10  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: add caching, use AC_CACHE_CHECK instead of AC_CACHE_VAL
	where possible, consistent message quoting, sync relevant
	tcl/unix/tcl.m4 HEAD changes and gratuitous formatting differences
	(notably sunc removal of support for for ancient BSD's, IRIX 4,
	RISCos and Ultrix by kennykb), Darwin improvements to
	TEA_LOAD_*CONFIG to make linking work against Tcl/Tk frameworks
	installed in arbitrary location, change TEA_PROG_* search order
	(look in *_BIN_DIR parents before *_PREFIX).

2006-01-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add dkf's system config refactor

2006-01-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: remove extraneous ' that causes bash 3.1 to choke

2005-12-19  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4 (TEA_PATH_TCLCONFIG &c): Look for tclConfig.sh &c
	in ${libdir}, where they are installed by default [Patch #1377407].

2005-12-05  Don Porter  <dgp@users.sf.net>

	* tcl.m4 (TEA_PUBLIC_*_HEADERS):	Better support for finding
	header files for uninstalled Tcl and Tk.

2005-12-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correctly bump TEA_VERSION var to 3.4

2005-12-01  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4 (Darwin): fixed error when MACOSX_DEPLOYMENT_TARGET unset

2005-11-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4:  *** Bump to TEA version 3.4 ***
	Add Windows x64 build support.
	Remove TEA_PATH_NOSPACE and handle the problem with ""s where
	necessary - the macro relied on TCLSH_PROG which didn't work for
	cross-compiles.

2005-11-27  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): add 64bit support, add CFLAGS to SHLIB_LD to
	support passing -isysroot in env(CFLAGS) to configure (flag can't
	be present twice, so can't be in both CFLAGS and LDFLAGS during
	configure), don't use -prebind when deploying on 10.4.
	(TEA_ENABLE_LANGINFO, TEA_TIME_HANDLER): add/fix caching.

2005-10-30  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: fixed two tests for TEA_WINDOWINGSYSTEM = "aqua" that
	should have been for `uname -s` = "Darwin" instead; added some
	missing quoting.
	(TEA_PROG_TCLSH, TEA_PROG_WISH): fix incorrect assumption that
	install location of tclConfig.sh/tkConfig.sh allows to determine
	the tclsh/wish install dir via ../bin. Indeed tcl/tk can be
	configured with arbitrary --libdir and --bindir (independent of
	prefix) and such a configuration is in fact standard with Darwin
	framework builds. At least now also check ${TCL_PREFIX}/bin
	resp. ${TK_PREFIX}/bin for presence of tclsh resp. wish (if tcl/tk
	have been configured with arbitrary --bindir, this will still not
	find them, for a general solution *Config.sh would need to contain
	the values of bindir/libdir/includedir passed to configure).

2005-10-07  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Fix Solaris 5.10 check and Solaris AMD64 64-bit builds.

2005-10-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_PRIVATE_TCL_HEADERS): add / to finish sed macro
	(TEA_ENABLE_THREADS): don't check for pthread_attr_setstacksize func

2005-09-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: *** Update to TEA version 3.3 ***
	define TEA_WINDOWINGSYSTEM in TEA_LOAD_TKCONFIG.
	Make --enable-threads the default (users can --disable-threads).
	Improve AIX ${CC}_r fix to better check existing ${CC} value.
	Do the appropriate evals to not require the *TOP_DIR_NATIVE vars
	be set for extensions that use private headers.
	Make aqua check for Xlib compat headers the same as win32.

2005-07-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
	TEA_PROG_WISH, TEA_BUILD_WISH): Remove
	TEA_BUILD_TCLSH and TEA_BUILD_WISH because
	of complaints that it broke the build when
	only an installed version of Tcl was available
	at extension build time. The TEA_PROG_TCLSH and
	TEA_PROG_WISH macros will no longer search the
	path at all. The build tclsh or installed
	tclsh shell will now be found by TEA_PROG_TCLSH.

2005-07-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
	TEA_PROG_WISH, TEA_BUILD_WISH):
	Split confused search for tclsh on PATH and
	build and install locations into two macros.
	TEA_PROG_TCLSH and TEA_PROG_WISH search the
	system PATH for an installed tclsh or wish.
	The TEA_BUILD_TCLSH and TEA_BUILD_WISH
	macros determine the name of tclsh or
	wish in the Tcl or Tk build directory even
	if tclsh or wish has not yet been built.
	[Tcl bug 1160114]
	[Tcl patch 1244153]

2005-06-23  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (TEA_PRIVATE_TK_HEADERS): add ${TK_SRC_DIR}/macosx to
	TK_INCLUDES when building against TkAqua.

	* tcl.m4 (TEA_PATH_X): fixed missing comma in AC_DEFINE

	* tcl.m4: changes to better support framework builds of Tcl and Tk out
	of the box: search framework install locations for *Config.sh, and if in
	presence of a framework build, use the framework's Headers and
	PrivateHeaders directories for public and private includes. [FR 947735]

2005-06-18  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
	ensure we can always relocate binaries with install_name_tool.

2005-06-04  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (TEA_PATH_X): for TEA_WINDOWINGSYSTEM == aqua, check if xlib
	compat headers are available in tkheaders location, otherwise add xlib
	sourcedir to TK_XINCLUDES.

2005-04-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: added AC_DEFINE* descriptions (from core tcl.m4) to allow
	use with autoheader.
	(Darwin): added configure checks for recently added linker flags
	-single_module and -search_paths_first to allow building with older
	tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD.
	(TEA_MISSING_POSIX_HEADERS): added caching of dirent.h check.
	(TEA_BUGGY_STRTOD): added caching (sync with core tcl.m4).

2005-03-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_TCL_64BIT_FLAGS): use Tcl header defaults for wide
	int type only on Windows when __int64 is detected as valid.

2005-03-24  Don Porter  <dgp@users.sf.net>

	* README.txt:	Update reference to "SC_* macros" to "TEA_* macros".
	* tcl.m4:	Incorporated recent improvements in SC_PATH_TCLCONFIG
	and SC_PATH_TKCONFIG into TEA_PATH_TCLCONFIG and TEA_PATH_TKCONFIG.
	Corrected search path in TEA_PATH_CONFIG and added
	AC_SUBST($1_BIN_DIR) to TEA_LOAD_CONFIG so that packages that load
	the configuration of another package can know where they loaded
	it from.

2005-03-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_CONFIG_CFLAGS): correct 2005-03-17 change to have
	variant LD_SEARCH_FLAGS for gcc and cc builds.

	* tcl.m4 (TEA_ADD_LIBS): don't touch lib args starting with -.
	(TEA_CONFIG_CFLAGS): only define _DLL for CE in shared build.
	(TEA_MAKE_LIB): set RANLIB* to : on Windows (it's not needed).

2005-02-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: redo of 2005-01-27 changes to correctly handle paths
	with spaces.  Win/CE and Win/64 builds now require a prebuilt
	tclsh to handle conversion to short pathnames.  This is done in
	the new TEA_PATH_NOSPACE macro.  For Win/CE|64, make CC just the
	compiler and move the necessary includes to CFLAGS.
	(TEA_CONFIG_CFLAGS): Add Solaris 64-bit gcc build support.
	(TEA_PROG_TCLSH, TEA_PROG_WISH): Allow TCLSH_PROG and WISH_PROG to
	be set in the env and prevent resetting.
	(TEA_ADD_LIBS): On Windows using GCC (mingw), convert foo.lib
	args to -lfoo, for use with mingw.
		*** POTENTIAL INCOMPATABILITY ***
	(TEA_CONFIG_CFLAGS): Fix AIX gcc builds to work out-of-box.
	Bumped TEA to 3.2.

2005-01-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: remove cygpath calls to support msys.
	Update base CE build assumption to "420,ARMV4,ARM,Pocket PC 2003".
	Make STLIB_LD use $LINKBIN -lib.

2005-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): fixed bug with static build linking to dynamic
	library in /usr/lib etc instead of linking to static library earlier
	in search path. [Tcl Bug 956908]
	Removed obsolete references to Rhapsody.

2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS

	* tcl.m4 (TEA_CONFIG_CFLAGS): support eVC4 Win/CE builds

2004-08-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_INIT, TEA_PREFIX): update handling of exec_prefix to
	work around subdir configures since autoconf only propagates the
	prefix (not exec_prefix).

2004-07-23  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (TEA_CONFIG_CFLAGS): Darwin section: brought inline with
	Tcl 8.5 HEAD config, removed core specific & obsolete settings.

2004-07-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_PATH_X): check in TK_DEFS for MAC_OSX_TK to see if
	we are compiling on Aqua.  Add TEA_WINDOWINGSYSTEM var that
	reflects 'tk windowingsystem' value.

2004-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_ENABLE_THREADS): force a threaded build when
	building against a threaded core.
	(CFLAGS_WARNING): Remove -Wconversion for gcc builds
	(TEA_CONFIG_CFLAGS): Reorder configure.in for better 64-bit build
	configuration, replacing EXTRA_CFLAGS with CFLAGS.  [Bug #874058]
	Update to latest Tcl 8.5 head config settings.
	Call this TEA version 3.1.

2004-04-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_TCL_64BIT_FLAGS): replace AC_TRY_RUN test with
	AC_TRY_COMPILE for the long vs. long long check. (kenny)

2004-04-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_TCL_64BIT_FLAGS): update against core tcl.m4 to
	define TCL_WIDE_INT_IS_LONG if 'using long'.

2004-03-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct Windows builds getting LDFLAGS info in MAKE_LIB

2004-02-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct TCL_INCLUDES for private headers on Windows - it
	doesn't need the eval.

2004-02-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: don't require TK_INCLUDES and TCL_INCLUDES to have the
	DIR_NATIVE vars defined when using private headers on unix.
	Allow $... to TEA_ADD_SOURCES for constructs like
	TEA_ADD_SOURCES([\$(WIN_OBJECTS)]), that allow the developer to
	place more in the Makefile.in.
	tkUnixPort.h checks for HAVE_LIMITS_H, so do both HAVE and
	CHECK on limits.h

2003-12-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* Makefile.in:      added TEA_ADD_LIBS, TEA_ADD_INCLUDES and
	* configure:        TEA_ADD_CFLAGS to configurable parameters with
	* configure.in:     PKG_* equivs in the Makefile.  This allows the
	* tclconfig/tcl.m4: user to worry less about actual magic VAR names.
	Corrected Makefile.in to note that TEA_ADD_TCL_SOURCES requires
	exact file names.

2003-12-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: updated OpenBSD support based on [Patch #775246] (cassoff)

2003-12-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* configure:
	* configure.in:
	* Makefile.in (VPATH): readd $(srcdir) to front of VPATH as the
	first part of VPATH can get chopped off.
	Change .c.$(OBJEXT) rule to .c.@OBJEXT@ to support more makes.
	* tclconfig/tcl.m4: add TEA_ADD_STUB_SOURCES to support libstub
	generation and TEA_ADD_TCL_SOURCES to replace RUNTIME_SOURCES as
	the way the user specifies library files.

2003-12-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* configure:           Update of TEA spec to (hopefully) simplify
	* configure.in:        some aspects of TEA by making use of more
	* Makefile.in:         AC 2.5x features.  Use PACKAGE_NAME (instead
	* generic/tclsample.c: of PACKAGE) and PACKAGE_VERSION (instead of
	* tclconfig/tcl.m4:    VERSION) arguments to AC_INIT as the TEA
	package name and version.
	Provide a version argument to TEA_INIT - starting with 3.0.
	Drop all use of interior shell substs that older makefiles didn't
	like.  Use PKG_* naming convention instead.
	Move specification of source files and public headers into
	configure.in with TEA_ADD_SOURCES and TEA_ADD_HEADERS.  These will
	be munged during ./configure into the right obj file names (no
	$(SOURCES:.c=.obj) needed).
	There is almost nothing that should be touched in Makefile.in now
	for the developer.  May want to add a TEA_ADD_TCL_SOURCES for the
	RUNTIME_SOURCES that remains.
	Use SHLID_LD_FLAGS (instead of SHLID_LDFLAGS) as Tcl does.
	Only specify the user requested LDFLAGS/CFLAGS in the Makefile,
	don't mention the _OPTIMIZE/_DEBUG variants.

2003-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: create a TEA_SETUP_COMPILER_CC the precedes the
	TEA_SETUP_COMPILER macro.  They are split so the check for CC
	occurs before any use of CC.  Also add AC_PROG_CPP to the compiler
	checks.

2003-10-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Updated for autoconf 2.5x prereq.
	Where TCL_WIDE_INT_TYPE would be __int64, defer to the code checks
	in tcl.h, which also handles TCL_LL_MODIFIER* properly.

2003-04-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct default setting of ARCH for WinCE builds.
	Correct \ escaping for CE sed macros.

2003-04-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: replace $(syscal) construct with older `syscall` for
	systems where sh != bash.

2003-04-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_WITH_CELIB): add --enable-wince and --with-celib
	options for Windows/CE compilation support.  Requires the
	Microsoft eMbedded SDK and Keuchel's celib emulation layer.

2003-02-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_ENABLE_THREADS): Make sure -lpthread gets passed on
	the link line when checking for the pthread_attr_setstacksize
	symbol. (dejong)

	* tcl.m4 (TEA_SETUP_COMPILER): added default calls to
	TEA_TCL_EARLY_FLAGS, TEA_TCL_64BIT_FLAGS,
	TEA_MISSING_POSIX_HEADERS and TEA_BUGGY_STRTOD.

2003-02-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct HP-UX ia64 --enable-64bit build flags

2003-01-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: check $prefix/lib as well as $exec_prefix/lib when
	looking for tcl|tkConfig.sh, as this check is done before we would
	set exec_prefix when the user does not define it.

2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* tcl.m4 (TEA_CONFIG_CFLAGS): Fix build support
	for mingw, the previous implementation would
	use VC++ when compiling with mingw gcc. Don't
	pass -fPIC since gcc always compiles pic code
	under win32. Change some hard coded cases
	of gcc to ${CC}.

2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to
	TEA_MAKE_LIB because setting too early confuses other AC_* macros.
	Correct the HP-11 SHLIB_LD_LIBS setting.

	* tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and
	make it pick up the env CFLAGS at configure time.

2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG.
	Improved AIX 64-bit build support, allow it on AIX-4 as well.
	Enable 64-bit HP-11 compilation with gcc.
	Enable 64-bit IRIX64-6 cc build support.
	Correct FreeBSD thread library linkage.
	Add OSF1 static build support.
	Improve SunOS-5 shared build SHLIB_LD macro.

2002-07-20  Zoran Vasiljevic  <zoran@archiware.com>

	* tcl.m4: Added MINGW32 to list of systems checked for Windows build.
	Also, fixes some indentation issues with "--with-XXX" options.

2002-04-23  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_ENABLE_THREADS): added USE_THREAD_ALLOC define to
	use new threaded allocatory by default on Unix for Tcl 8.4.
	(TEA_CONFIG_CFLAGS): corrected LD_SEARCH_FLAGS for FreeBSD-3+.

2002-04-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_SETUP_COMPILER): removed call to AC_CYGWIN so that
	we can use autoconf 2.5x as well as 2.13.  This prevents us from
	being able to warn against the use of cygwin gcc at configure
	time, but allows autoconf 2.5x, which is what is shipped with most
	newer systems.

2002-04-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Enabled COFF as well as CV style debug info with
	--enable-symbols to allow Dr. Watson users to see function info.
	More info on debugging levels can be obtained at:
	http://msdn.microsoft.com/library/en-us/dnvc60/html/gendepdebug.asp

2002-04-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: change all SC_* macros to TEA_*.  The SC_ was for
	Scriptics, which is no more.  TEA represents a better, independent
	prefix that won't need changing.
	Added preliminary mingw gcc support. [Patch #538772]
	Added TEA_PREFIX macro that handles defaulting the prefix and
	exec_prefix vars to those used by Tcl if none were specified.
	Added TEA_SETUP_COMPILER macro that encompasses the AC_PROG_CC
	check and several other basic AC_PROG checks needed for making
	executables.  This greatly simplifies user's configure.in files.
	Collapsed AIX-5 defines into AIX-* with extra checks for doing the
	ELF stuff on AIX-5-ia64.
	Updated TEA_ENABLE_THREADS to take an optional arg to allow
	switching it on by default (for Thread) and add sanity checking to
	warn the user if configuring threads incompatibly.

2002-03-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: made sure that SHLIB_LDFLAGS was set to LDFLAGS_DEFAULT.
	Removed --enable-64bit support for AIX-4 because it wasn't correct.
	Added -MT or -MD Windows linker switches to properly support
	symbols-enabled builds.

2002-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: called AC_MSG_ERROR when SC_TEA_INIT wasn't called first
	instead of calling it as that inlines it each time in shell code.
	Changed Windows CFLAGS_OPTIMIZE to use -O2 instead of -Oti.
	Noted TCL_LIB_VERSIONS_OK=nodots for Windows builds.
	A few changes to support itcl (and perhaps others):
	Added support for making your own stub libraries to SC_MAKE_LIB.
	New SC_PATH_CONFIG and SC_LOAD_CONFIG that take a package name arg
	and find that ${pkg}Config.sh file.  itk uses this for itcl.

2002-03-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: made SC_LOAD_TKCONFIG recognize when working with a Tk
	build dir setup.
	Added EXTRA_CFLAGS and SHLIB_LD_LIBS substs to SC_CONFIG_CFLAGS.
	Added XLIBSW onto LIBS when it is defined.
	Remove TCL_LIBS from MAKE_LIB and correctly use SHLIB_LD_LIBS
	instead to not rely as much on tclConfig.sh cached info.
	Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH.
	These move towards making TEA much more independent of *Config.sh.

2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and
	SHLIB_SUFFIX defines for Win.
	(SC_PATH_X): made this only do the check on unix platforms.

2002-03-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* README.txt: updated to reflect fewer files

2002-03-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* config.guess (removed):
	* config.sub (removed): removed unnecessary files

	* installFile.tcl (removed):
	* mkinstalldirs (removed): these aren't really necessary for
	making TEA work

	* tcl.m4 (SC_PUBLIC_TCL_HEADERS, SC_PUBLIC_TK_HEADERS): don't
	check /usr(/local)/include for includes on Windows when not using
	gcc

2002-03-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: added warnings on Windows, removed RELPATH define and
	added TCL_LIBS to MAKE_LIB macro.

	This import represents 2.0.0, or a new start at attempting to
	make TEA much easier for C extension developers.

	**** moved from tclpro project to core tcl project, ****
	**** renamed to 'tclconfig'                         ****

2001-03-15    Karl Lehenbauer <karl@procplace.com>

	* installFile.tcl: Added updating of the modification time of
	  the target file whether we overwrote it or decided that it
	  hadn't changed.  This was necessary for us to be able to
	  determine whether or not a module install touched the file.

2001-03-08    Karl Lehenbauer <karl@procplace.com>

	* installFile.tcl: Added support for converting new-style (1.1+)
	  Cygnus drive paths to Tcl-style.

2001-01-15    <brent.welch@interwoven.com>

	* tcl.m4: Added FreeBSD clause.

2001-01-03    <brent.welch@interwoven.com>

	* tcl.m4: Fixed typo in SC_LIB_SPEC where it is checking
	for exec-prefix.

2000-12-01    <brent.welch@interwoven.com>

	* tcl.m4: Concatenated most of the Ajuba acsite.m4 file
	so we don't need to modify the autoconf installation.
	* config.guess:
	* config.sub:
	* installFile.tcl:
	Added files from the itcl config subdirectory,
	which should go away.

2000-7-29    <welch@ajubasolutions.com>

	* Fixed the use of TCL_SRC_DIR and TK_SRC_DIR within
	TCL_PRIVATE_INCLUDES and TK_PRIVATE_INCLUDES to match their recent
	change from $(srcdir) to $(srcdir)/..

These files comprise the basic building blocks for a Tcl Extension
Architecture (TEA) extension.  For more information on TEA see:

#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
#                       of a shared library (may request position-independent
#                       code, among other things).
#       SHLIB_LD -      Base command to use for combining object files
#                       into a shared library.
#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
#                       creating shared libraries.  This symbol typically
#                       goes at the end of the "ld" commands that build
#                       shared libraries. The value of the symbol defaults to
#                       "${LIBS}" if all of the dependent libraries should
#                       be specified when creating a shared library.  If
#                       dependent libraries should not be specified (as on
#                       SunOS 4.x, where they cause the link to fail, or in
#                       general if Tcl and Tk aren't themselves shared
#                       libraries), then this symbol has an empty string
#                       as its value.
#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
#                       extensions.  An empty string means we don't know how
#                       to use shared libraries on this platform.
#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
#                       in a static or shared library name, using the $VERSION variable
#                       to put the version in the right place.  This is used
#                       by platforms that need non-standard library names.
#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
#                       to have a version after the .so, and ${VERSION}.a
#                       on AIX, since a shared library needs to have
#                       a .a extension whereas shared objects for loadable
#                       extensions have a .so extension.  Defaults to
#                       ${VERSION}${SHLIB_SUFFIX}.
