Created attachment 551930 [details] emerge_info Hi, I possibly have a non-standard USE for media-libs/mesa, but since 18.2.x pre-release it fails to build for me, I finally took some time to take a look what it could be, and I'm far from someone who knows 100% what the issue is, and if my fix is right. In the end it seems on my multilib system it requires dev-libs/elfutils[abi_x86_32] as well. I created a patch which I think is right and I can provide a pull request over github if you think this is right. I'll attach build log, and emerge --info, as well as simple diff with an idea what I think solves the issue. Comments are welcome.

I created a branch here at https://github.com/bitlord/gentoo/tree/media-libs/mesa I can create a pull request if this makes sense.
Looks like it's no vdpau that requires libelf, but the radeon drivers themselves. In meson.build we have: if with_amd_vk or with_gallium_radeonsi or with_gallium_r600 or with_gallium_opencl dep_elf = dependency('libelf', required : false) if not dep_elf.found() dep_elf = cc.find_library('elf') endif else dep_elf = null_dep endif But in configure.ac we have: if test "x$have_libelf" != xyes; then AC_MSG_ERROR([$2 requires libelf when using llvm]) fi and if test "x$have_libelf" != xyes; then AC_MSG_ERROR([Clover requires libelf]) fi So I think you've found a bug in the upstream Meson build system :) Cc'ing the Meson build system maintainer. Dylan, the problem as I see it is that Meson currently requires libelf when radeonsi/r600 is built regardless of whether llvm is enabled.
Well, radeonsi and radv have a hard requirement on LLVM, so this really only applies to r600, but yeah, I think this is a bug in the meson logic. I'll send a patch.
I've sent a patch to the list, you can see it here. I've compile tested it, but I don't have an r600 card anymore, so if you could be so kind as to test that it actually works I'd appreciate that. https://gitlab.freedesktop.org/dbaker/mesa/commits/fix-r600-libelf
I reviewed the patch upstream. I'd expect it to be in 18.2.4.
The patch has landed in master, it should be queued for the next stable release.
