I know this subject has been on the list a lot, but even from reading
the archives I've not been able to figure out what's going wrong. I am
trying to compile SDL_mixer with Ogg Vorbis support. I downloaded,
compiled and installed the Vorbis libraries with no problem. That's
what I thought anyway.
When compiling SDL_mixer, it fails when linking everything together at
the end:
/usr/local/lib/libvorbisfile.a(vorbisfile.o.b)(.text+0x2ad6):vorbisfile.c:
undef
ined reference to `__errno'
/usr/local/lib/libvorbisfile.a(vorbisfile.o.b)(.text+0x2b5e):vorbisfile.c:
undef
ined reference to `__errno'
/usr/local/lib/libvorbis.a(info.o)(.text+0xbc2):info.c: undefined
reference to `
_imp___ctype_'
/usr/local/lib/libvorbis.a(info.o)(.text+0xcc2):info.c: undefined
reference to `
_imp___ctype_'
make[1]: *** [libSDL_mixer.la] Error 1
make[1]: Leaving directory `/devel/SDL_mixer-1.2.4'
make: *** [all-recursive] Error 1
Now when I say I know this has been covered on the list, I mean that I
found a lot of posts talking about using g++ with -mno-cygwin, but I
don't think any of these programs are using c++. There were also posts
of missing libraries in /usr/lib/mingw, but they all seem to be there.
If I grep or use nm on them, I do see references to __errno and
_imp___ctype_. I tried many ways of linking the libraries into the
program without any change in the result. Perhaps there are cygwin
versions of the same libs that are always getting linked first? If so,
how do I change the order? This has been driving me mad....
Thanks
