[MACTCL] Problem with tclConfig.sh in BI Distro

[Bernard D. <bde...@ea...>]

Hi Daniel,

I just wanted to mention a problem I have met using the tclConfig.sh files
included in the BI Distro.

Context: I've been introducing TEA (3.4) support for the Tclresource 
extension
recently. It basically works fine.
Since Tclresource invokes the TclGetOpenMode() function, I have to include
the tclInt.h private header. This function is in the TclIntStubs table.

So I do the following:
* in my configure.ac file, I enable the TEA_PRIVATE_TCL_HEADERS macro

* I generate the configure script with autoconf

* I run this configure script. This generate the Makefile from Makefile.in

* now in the Makefile I obtain, the INCLUDES variable is defined like this
INCLUDES    =  
-I"/Volumes/Local/Users/steffen/Documents/Development/TclTk/tcltkaqua-8_4_7_0/source/tcl/generic" 
-I"/Volumes/Local/Users/steffen/Documents/Development/TclTk/tcltkaqua-8_4_7_0/source/tcl/unix"

which means that it does not contain the necessary
-I"/Library/Frameworks/Tcl.framework/Headers" 
-I"/Library/Frameworks/Tcl.framework/PrivateHeaders"


Looking in the tcl.m4 file at the definition of TEA_PRIVATE_TCL_HEADERS
(ditto in the resulting configure script), I
see that this depends on the following test:
case ${TCL_DEFS} in
*TCL_FRAMEWORK*)
if test -d "${TCL_BIN_DIR}/Headers" -a -d 
"${TCL_BIN_DIR}/PrivateHeaders"; then
etc.


It fails there because the TCL_FRAMEWORK value is not found in ${TCL_DEFS}.
Indeed the definition for TCL_DEFS is taken from the tclConfig.sh script
in the framework and it contains no "-DTCL_FRAMEWORK=1".

This is weird because, on another machine, I have recently rebuilt the
Tcl.framework from the latest sources on CVS, so I have a locally
generated tclConfig.sh and its definition of TCL_DEFS does contain
"-DTCL_FRAMEWORK=1" so that the Makefile I obtain correctly has the
following value for the INCLUDES  variable:
INCLUDES    =  -I"/Library/Frameworks/Tcl.framework/Headers" 
-I"/Library/Frameworks/Tcl.framework/PrivateHeaders" 
-I"/Volumes/im2/Tcl/Tcl_Sources/TclTk_HEAD/tcl/generic" 
-I"/Volumes/im2/Tcl/Tcl_Sources/TclTk_HEAD/tcl/unix"

I can workaround this by rebuilding the Tcl framework on my iBook (just as
I did on my G5), but I just wondered whether the absence of
"-DTCL_FRAMEWORK=1" in TCL_DEFS is normal, or whether the test in
TEA_PRIVATE_TCL_HEADERS should rely on something else, or whether I'm
missing something.


Cheers,

Bernard
