The multilib overlay (http://wiki.github.com/sjnewbury/multilib-overlay/) adds support for building both 32-bit and 64-bit libraries on Gentoo with a single emerge command. However, with that overlay, 32-bit libvpx builds incorrectly (/usr/lib32/libvpx.so.0.9.0 ends up being a 64-bit library). Reproducible: Always Steps to Reproduce: 1. Install Gentoo with multilib overlay on amd64 (use the portage-multilib branch, expect spending some time fighting circular dependencies). 2. Install libvpx with the lib32 USE flag (added by that patched portage) 3. Inspect the /usr/lib32/libvpx.so.0.9.0 library with the "file" command Maybe it is enough to do ABI=x86 emerge -av libvpx on a regular amd64 Gentoo box, without the multilib overlay. If it is so, please state this in your comment and adjust the summary to "builds incorrectly with ABI=x86" - I don't have such box and can't check. Actual Results: /usr/lib32/libvpx.so.0.9.0 is a 64-bit library Expected Results: /usr/lib32/libvpx.so.0.9.0 should be a 32-bit library This patch works for me, but it is obviously wrong WRT FreeBSD

Not surprisingly, this library is using approximately the same kind of magical arch detection as in the chromium ebuild. See bug #296917 . We need to override this, not just for multilib overlay, but also for people with 64-bit kernel, 32-bit userland or cross-compilers. The bug above gives the logic required.
(In reply to comment #1) > [...] The bug above gives the logic required. Specifically bug #296917 comment 6, not the patch on that bug
Retitling the bug as advised on #gentoo-multilib-overlay
That's an upstream problem, we'll try to solve it with them
Created attachment 257253 [details, diff] libvpx multilib patch this is a patch for the actual stable to get it compile with portage multilib it also correct a autodetect problem related to using yasm commands with gnu-as
Same for this one: If there is no response or action within the next 2 weeks, i will touch libvpx and do the needed changes.
If you need amd64 support cc back us.

Seems like i forgot about this one, now done: +*libvpx-1.0.0-r1 (06 May 2012) + + 06 May 2012; Thomas Sachau (Tommy[D]) <tommy@gentoo.org> + +libvpx-1.0.0-r1.ebuild: + Add explicit targets for amd64 and x86 target platforms to allow + cross-compilation, build system seems to ignore user CFLAGS/LDFLAGS, bug + 325701 + leaving this bug open for the maintainer to decide about a different solution or to close this bug
should be all fixed these days
