I think it's visible only in the Debian family because we're configuring perl with -Duse64bitint. You should be able to reproduce it with a 32 bit perlbrew build using that. Testing with perl -MInline=NOISY xs_effects.pl confirms the compiler options from $Config{ccflags} is missing. Plain 'use Inline C' code doesn't have this problem, It only happens with use Inline with => 'SDL'; The problem seems to be in libsdl-perl; lib/SDL.pm has my $cflags = Alien::SDL->config('cflags'); [...] return { LIBS => $libs, CCFLAGS => $cflags, TYPEMAPS => $path, AUTO_INCLUDE => '#include <SDL.h>' }; which apparently makes Inline overwrite $Config{ccflags} altogether. Reading the Inline::C manual page, CCFLAGSEX would probably be a better choice. Indeed, patching CCFLAGSEX in makes the build succeed here. (The actual effects didn't seem to work for me, but somebody actually familiar with the SDL bindings should probably test that. In any case, that seems even less like a problem in the Perl core.) Reassigning. Once there's a tested fix, I think it should be considered for a stable update. -- Niko Tyni [email protected] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
