Created attachment 325282 [details, diff] Upstream patch Opus-tools works on x86 if this [1] upstream patch is included. [1] http://git.xiph.org/?p=opus-tools.git;a=commit;h=7734f55bc535c6d3d0fbb27c55e38f52ba6b7764
There's a new version: opus-tools 0.1.6 which should also resolve that problem.
0.1.6 now in portage. x86-team: I think this should get ~x86, but I have no non-amd64-system to test.
opus-tools-0.1.6 compiles fine on x86. opus{info,enc,dec} do their job.
x86 done
