| Subject: | Build fails (in blead, at least) with www.mingw.org's gcc-4.8.1 |
Trying to build bleadperl with www.mingw.org's gcc-4.8.1 (I just used the download/setup program from their website to get the latest version of everything) I first ran into a core problem with DllMain, which I have logged as rt.perl.org #121643, but will have fixed soon (DllMain's first parameter should be a HINSTANCE, not a HANDLE). Having got over that the build then continued as far as the cpan/Win32 extension, which failed with the output below, in which the main error is "ws2tcpip.h is not compatible with winsock.h. Include winsock2.h instead" from c:\dev\software\mingw\4.8.1\include\ws2tcpip.h:38:2.
I will leave the rt.perl.org ticket open until this rt.cpan.org ticket is also fixed since blead won't build with www.mingw.org's gcc-4.8.1 until this is also fixed.
Note that the rt.perl.org ticket is marked as a blocker for the release of Perl 5.20, due in the next month or so, so a new Win32 CPAN release with this fixed would be greatly appreciated.
Simply inserting
#include <winsock2.h>
before #include <windows.h> in Win32.xs fixed the problem for me, but I have not considered whether that's an appropriate patch in all cases, especially for older perls.
