It happens every time for me on two different machines (Windows 7 and Windows 8.1). The build sequence with a straight "dmake" is: miniperl.exe DynaLoader XS extensions perl.dll perl.exe non-XS extensions The problem is that POSIX is an XS extension, but its Makefile.PL needs XSLoader, which is non-XS so hasn't been made yet. The POSIX Makefile.PL fails every time with this error: Can't locate XSLoader.pm in @INC (you may need to install the XSLoader module) (@INC contains: [...]) at C:\Dev\Git\perl\lib/B.pm line 26. BEGIN failed--compilation aborted at C:\Dev\Git\perl\lib/B.pm line 28. Compilation failed in require at C:\Dev\Git\perl\cpan\ExtUtils-MakeMaker\lib/ExtUtils/MakeMaker/version/vpp.pm line 954. 512 from ext/POSIX's Makefile.PL at ..\make_ext.pl line 523. It's the WriteConstants() call that fails. WriteMakefile() has already run successfully by this stage, so a Makefile has been written and POSIX.dll builds, but const-c.inc and const-xs.inc end up zero size. (Crucially, they *exist* so the #include in POSIX.c doesn't fail, hence the build continues.)Thread Previous | Thread Next
