I think gcc already provides a way to find out the multiarch directory, so it should be only a matter of patching gcc. Upstream would then just use gcc -print-multi-os-directory to find out the path (when building with gcc). For example I currently get this: On Linux: $ gcc -print-multi-os-directory . $ gcc -print-multi-os-directory -m32 ../../lib32 And on Solaris: $ gcc -print-multi-os-directory . $ gcc -print-multi-os-directory -m64 sparcv9 So it should be a matter of changing that to print this instead on Debian multiarch: $ gcc -print-multi-os-directory x86_64-linux-gnu $ gcc -print-multi-os-directory -m32 i486-linux-gnu (or whatever -m32 will use) For example of packages that have been using gcc's -print-multi-os-directory since quite some time are: - ltdl (libtool.m4): to find the runtime search path of the linker - ClamAV: to automatically install to /usr/lib32 when you compile with -m32 For example here is an GPLv2 m4 macro to "guess" the multilib directory: http://git.clamav.net/gitweb?p=clamav-devel.git;a=blob;f=m4/acinclude.m4#l844 If gcc was patched to output the correct multiarch directory then no upstream changes would be required for these packages.
