Subject: 64bit MS Windows failure (Controls.c)
Hi,

during my tests on 64bit Strawberry Perl 5.12.0-RC0 + Wx-0.9701 I have eperienced the following error:

g++  -fvtable-thunks  -O2 -mthreads -Os -c  -I. -I. -ID:\strawberry64\perl\site\lib\Alien\wxWidgets\msw_2_8_10_uni_gcc_3_4\lib -ID:\strawberry64\perl\site\lib\A

cc1plus.exe: warning: switch '-fvtable-thunks' is no longer supported
Controls.c: In function 'void XS_Wx__ListCtrl_SortItems(PerlInterpreter*, CV*)':

Controls.c:21328: error: cast from 'SV*' to 'long int' loses precision
dmake.EXE:  Error code 129, while making 'Controls.o'

Note: on 64bit MS Windows sizeof(*void) == 8 however sizeof(long int) == 4 therefore casting pointer to longint raises an error

The compilation fix is already committed (rev 2843). Note that this is only half of the fix: wxWidgets needs to be patched to accept a wxIntPtr (as it is in 2.9.0), otherwise the cast only hides the problem. Show quoted text

I know :-) Regards, Mattia

I just want to say that I get the exact same bug as kmx on Strawberry Perl 5.12.0 x64. Error message here: http://gist.github.com/390559 I have also sent a CPAN::Reporter report.

The latest dev release on CPAN seems to actually work (it builds and tests pass). Unfortunately Win32::API has some x64 errors, so Padre still doesn't build. :(
Fixed in 0.9702.
