Bug #67320 for Win32-API: Win32::API Callback won't install

Subject:

Win32::API Callback won't install

I am running windows version Windows 7 Home Premium x86_64bit, Strawberry Perl ver 5.12.2, using makemaker version 6.56. About a month ago we got the Win32::API (ver 0.60) running on my machine, but I noticed Callback wasn't implimented. I thought maybe it was a separate download but when I went to CPAN the download was the API (ver 0.62). I tried it to be sure nothing was different but Callback still isn't implimented although the rest of the API package compiled and installed perfectly. Cosimo tells me that this is presently a 64 bit issue so this is just the reminder he asked for. By the way, in the compiling and testing there was no mention of the Callback routine in the printout that insued although the Callback.pm module was found in the root folder and a Callback folder was generated with the Callback.xs and makefile.

Hi Bob, thanks for filing a ticket. I looked at the code again, and the callback part was indeed disabled on purpose on 64 bit builds because it's currently not working, so the tests would fail. This is the relevant part of Makefile.PL: 'PM' => { ... $is_64bit_build ? () : ('Callback.pm' => '$(INST_LIBDIR)/API/Callback.pm'), }, If you change it to: 'PM' => { ... 'Callback.pm' => '$(INST_LIBDIR)/API/Callback.pm', }, then the Callback part will be enabled.

I was too quick on that one. Here's the (reversed) patch that will allow compilation of Win32::API::Callback on 64 bit builds: https://github.com/cosimo/perl5-win32-api/ commit/7bc695d94f98566d3ad90ec53b3d978935495e94 so, it needs changes to Callback/Makefile.PL too, not just Makefile.PL. Sorry for the confusion.

Made the changes to both makefile.pl's this time from the commit page. Results were nearly the same (everything compiled fine and the API stuff works) except the this time because we leave out the callback.pm hash from the main makefile, it doesn't copy the module to the library at all so my error message this time when I try to run the Callback program is: D:\MyPerl\Perl\Programs\XS\Development>callback2.pl Can't locate Win32/API/Callback.pm in @INC (@INC contains: C:/strawberry/perl/site/lib C:/strawberry/perl/vendor/lib C:/strawberry/perl/lib .) at D:\MyPerl\Perl\Programs\XS\Development\callback2.pl line 5. BEGIN failed--compilation aborted at D:\MyPerl\Perl\Programs\XS\Development\callback2.pl line 5. Then, if I copy the module to the library manually I get the old "Can't locate loadable object" error.

Win32::API v0.64 is on its way to CPAN, and it's also pushed to Github at https://github.com/cosimo/perl5-win32-api/ This version has a clearer Makefile.PL that will correctly build or not build the Callback module depending on a "$build_callback" flag instead of avoiding build if it's a 64 bit architecture. The two flags are still linked together by default (64 bit arch => no callback) because the Callback tests would fail anyway, but it should be easier for anyone to just enable/disable callback module by changing the "$build_callback" flag in: * Makefile.PL * Callback/Makefile.PL I'll fix as resolved. Please get in touch if there's problems.

I changed the two $build_callback flags and installed the new revision. Everything seemed to work fine in testing and installing. But now that it's installed, none of the sample callback programs work still. They come up with an error saying "Perl has stopped working. Trying to find out why". Then when the resolution pops up it says, "The thread tried to read from or write to a virtual address for which it does not have the appropriate access". If there is something I'm doing wrong could you tell me what might cause such an error? These were the 3 sample callback programs in the package. Thanks, Bob Ross Show quoted text
