Problem manifests itself as a failed linking of the 32bit part of libSDL2_mixer-2.0.so because /usr/bin/smpeg2-config has -L/usr/lib64 hardcoded. Workaround is to either set -smpeg or -abi_x86_32 for media-libs/sdl2-mixer. Failure output looks as follows: ...

Get a multilib system going with abi_x86_[32,64] and ACCEPT_KEYWORDS=~amd64 2. Set smpeg use flag globally or just for media-libs/sdl2-mixer. 3. Emerge media-libs/sdl2-mixer. Actual Results: Fails to link properly with various libs in /usr/lib64 during the link stage of the 32bit library. -L/usr/lib64 shouldn't be used for this, but it is brought in by /usr/bin/smpeg2-config. Expected Results: emerged both 32bit and 64bit versions os libSDL2_mixer. This bug might depend on upstream smpeg to add proper /usr/lib[32,64]/pkgconfig .pc files. This is in /usr/bin/smpeg2-config: --libs) if [ "`uname`" = "SunOS" ]; then libdirs="-L/usr/lib64 -R/usr/lib64" else libdirs="-L/usr/lib64 " fi
Created attachment 395666 [details, diff] Bumping revision to require eautoreconf for new smpeg2 aclocal. This complements the smpeg2 patch as a dependency and should allow this package to merge with multilib and smpeg.
It would be great if someone on the multilib team could try this out and apply if it seems right.
I've sent the patch for smpeg2 upstream to icculus@icculus.org so this might be a no-action-required if its included in the next release. I think sdl2-mixer would still need a new configure script built without always enabling eautoconf like in this patch.
I think this has been worked around in smpeg2
