Default library links for 32 bit libs on x86_64

[Dirk_R]

Hi everybody,

I'm struggling with compiling apps in 32 bit mode on my x86_64 box. Using -m32 the compilation works fine. But linking fails, because many of the libs in /usr/lib are only versioned (e.g. libjpeg.so.62 and libjpeg.so.62.0.0), but it's missing the generic libjpeg.so link, so 'gcc test.c -ljpeg' just fails because it can't find anything.

So far I've just kludged it by creating those links myself, but that's not a solution. Why are those links missing?

Thanks

Dirk

Have you tried preceding the make or gcc commands with the 'linux32' command? This fools the system making it think it running on i686, I think this also affects the LD_LIBARY_PATH environment variable to point to /usr/lib instead of /usr/lib64 by default.

Install the i386 versions of the -devel rpms for whatever libraries you need. That'll give you the necessary symlinks without having to create files by hand in /usr, which makes baby Jesus (and rpm) cry.
