Hit the same problem.

Created attachment 394370 [details, diff] Fix the configure script for the case when LD is set This is because the package has its own multilib support, which inteferes with Gentoo's. If they detect that you're trying to cross compile 32-bit binaries on a 64-bit machine, they do this: gcc*) add_cflags -m${bits} add_ldflags -m${bits} link_with_cc=gcc tune_cflags="-march=" setup_gnu_toolchain In this case, they want to use gcc as ld. setup_gnu_toolchain() { CC=${CC:-${CROSS}gcc} CXX=${CXX:-${CROSS}g++} AR=${AR:-${CROSS}ar} LD=${LD:-${CROSS}${link_with_cc:-ld}} AS=${AS:-${CROSS}as} STRIP=${STRIP:-${CROSS}strip} NM=${NM:-${CROSS}nm} AS_SFX=.s EXE_SFX= } We have link_with_cc=gcc. So ${CROSS}${link_with_cc:-ld} gives you the right thing. Except that if LD is set, we won't touch it. And sure enough, LD is set in our multilib.eclass http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/multilib.eclass?diff_format=s&revision=1.106&view=markup: 426 # We want to avoid the behind-the-back magic of gcc-config as it 427 # screws up ccache and distcc.

If you decided that you want to use gcc as ld, you want that whether user have their own custom ld or not. In that case, we should pick up the ${CC} instead of ${LD} as our ld: diff -upr gstreamer-vaapi-0.5.9.orig/ext/libvpx/upstream/build/make/configure.sh gstreamer-vaapi-0.5.9/ext/libvpx/upstream/build/make/configure.sh --- gstreamer-vaapi-0.5.9.orig/ext/libvpx/upstream/build/make/configure.sh 2015-01-19 17:36:53.150477316 -0800 +++ gstreamer-vaapi-0.5.9/ext/libvpx/upstream/build/make/configure.sh 2015-01-19 18:35:37.469918858 -0800 @@ -587,7 +587,11 @@ setup_gnu_toolchain() { CC=${CC:-${CROSS}gcc} CXX=${CXX:-${CROSS}g++} AR=${AR:-${CROSS}ar} - LD=${LD:-${CROSS}${link_with_cc:-ld}} + if [ -n "${link_with_cc}" ]; then + LD=${CC:-${CROSS}${link_with_cc}} + else + LD=${LD:-${CROSS}ld} + fi AS=${AS:-${CROSS}as} STRIP=${STRIP:-${CROSS}strip} NM=${NM:-${CROSS}nm} You can drop this patch in the right place under /etc/portage/patches to get it to compile. Unfortunately, multilib doesn't call epatch_user. So you have to drop your bashrc to get the patch applied as described here: http://wiki.gentoo.org/wiki//etc/portage/patches
I've tested the patch, and it works. Thank you.
Maybe a better option could be to move from builtin vpx to system one. For that, we should use --enable-builtin-libvpx=no and RDEPEND on media-libs/libvpx
(In reply to Pacho Ramos from comment #5) > Maybe a better option could be to move from builtin vpx to system one. For > that, we should use --enable-builtin-libvpx=no and RDEPEND on > media-libs/libvpx I created an updated ebuild to test this approach and it seems to work. At the very least, gst-plugins-vaapi-0.5.9 did emerge. Perhaps a complete solution would be to apply this approach as well as patch configure.sh? I'll also upload my new ebuild in case anyone else wants to test it.

Confirming bug and that updated ebuild works, thanks a lot! :) /Charlie
https://gitorious.org/vaapi/gstreamer-vaapi/commits/master -> I think we should forward this to upstream to not need to carry that patch forever, but I cannot find any bug tracker or similar :S, are you familiar with gitorious?

I'm not familiar with gitorious, but I found a README in the source tree (https://gitorious.org/vaapi/gstreamer-vaapi/source/09bb0d4b5d5fa7b6c8821c7bcac96b5a068158ee:README) that said to file bugs at https://bugzilla.gnome.org/enter_bug.cgi?product=gstreamer-vaapi
Nice, thanks! Could you please report it then? I am a bit busy now :S
submitted. The report is at https://bugzilla.gnome.org/show_bug.cgi?id=743272 The bulk of the submission is based off the write-up in comment #3, so many thanks to Siuchung Cheung.
