it built fine for me. is it related to your CFLAGS ?
Yes, is it related to my CFLAGS. When compiling with CFLAGS -mno-sse4.1 -mno-avx, everything is fine. When compiling with CFLAGS -msse4.1 -mno-avx, fail. When compiling with CFLAGS -msse4.1 -mavx ( -march=corei7 ? ), I guess it will fail, too.
(In reply to comment #4) > it built fine for me. is it related to your CFLAGS ? Not in my case, as can be seen from the emerge --info provided.
Just to be clear, rev. 1.1 built fine for me on amd64, but not on x86, and this one, rev. 1.4 builds on x86 but not on amd64.
earlier revs isn't terribly relevant to the "__floorf is getting defined earlier". i know what patch is triggering this failure, but i'm more interested in the root cause, and that patch is most likely not it.
I getting this as well. Using --march=bdver1. "-mno-sse4.1 -mno-avx" fixes the install. @Chris What does this output. "gcc -Q --help=target -march=native" Your --march=native could be bringing in things in that you don't realize.
