| Subject: | Problems compiling on x64 ActivePerl (Win Vista 64) |
Hi,
I had to make a few amendments to get 804.028 and 804.028_501 to build
using the 64-bit version of ActivePerl 5.10.0 (build 1004) on Windows
Vista 64.
Note: I'm using the same compiler as was used to build that perl -
namely, Platform SDK for Windows Server 2003 R2.
1) In tkGlue.c, it seems that USE_NEWSTYLE_REGEXP_STRUCT needs to be
set to a true value, but is not. My workaround was to simply patch
tkGlue.c as follows:
--- tkGlue.c Fri May 15 21:42:53 2009
+++ tkGlue.c_fixed Fri May 15 20:17:15 2009
@@ -5406,7 +5406,7 @@
#else
regexp *re = wrap->pat;
#endif
-#if USE_NEWSTYLE_REGEXP_STRUCT
+#if 1 /* USE_NEWSTYLE_REGEXP_STRUCT */
if (re->offs[index].start != -1 && re->offs[index].end != -1)
{
*startPtr = re->subbeg+re->offs[index].start;
Clearly, this is not a portable solution. In fact, I don't think it's
even portable across different Microsoft Compilers.

The changes in relation to bufferoverflowU.lib are inadequate for 2
reasons:
a) They're being applied to generated files, not to source files. (Any
pointers on how to implement those changes via amendments to the source
files ?)
b) They utilise a hard coded 'bufferoverflowU.lib', which is clearly
not portable. I *can*, however, help with this aspect. A portable
solution would be to replace the hard coded 'bufferoverflowU.lib' with
$Config{perllibs} - as $Config{perllibs} includes 'bufferoverflowU.lib'
*iff* that library is needed.
Any thoughts on how to transform my hacks into a useful solution would
be appreciated.
With those changes in place, Tk compiled fine, and passed the test
suite.
Cheers,
Rob
