Description Laurent Bachelier 2017-01-12 18:42:50 UTC

Created attachment 459806 [details]
build.log

On one of my CPUs (AMD Turion(tm) Neo X2 Dual Core Processor L625) the compiling fails (see attached build.log). It's the only one without a sse4_1 flag in /proc/cpuinfo.

It fails there:
Makefile:1004: recipe for target 'libwebpdsp_sse41_la-enc_sse41.lo' failedmake[2]: *** [libwebpdsp_sse41_la-enc_sse41.lo] Error 1

I added --disable-sse4.1 to the args array in the ebuild and it then compiled fine.

I suppose the ebuild should make use of the CPU_FLAGS_X86 variable.

You have those silly -mno-xxx settings in your CFLAGS. You don't need them, and they interfere with the flags added by the build system.
