Created attachment 222507 [details] build.log build.log+emerge --info
From bug 290898, doing this: --- /usr/portage/dev-libs/crypto++/crypto++-5.6.0-r1.ebuild 2010-03-07 18:05:31.000000000 +0000 +++ crypto++-5.6.0-r1.ebuild 2010-03-13 13:19:35.000000000 +0000 @@ -28,6 +28,7 @@ replace-flags -O? -O1 filter-flags -fomit-frame-pointer use sse3 || append-flags -DCRYPTOPP_DISABLE_SSE2 + use amd64 && append-flags -DCRYPTOPP_DISABLE_ASM emake -f GNUmakefile \ LIBDIR="$(get_libdir)" \ CXX="$(tc-getCXX)" CXXFLAGS="${CXXFLAGS}" || die "emake failed" Fixes this bug and probably bug 300547, which fails for me the same way if USE="sse3". In other words, adding the flag above fixes: - FEATURES="test" USE="-sse3" emerge -v crypto++ - FEATURES="test" USE="sse3" emerge -v crypto++
Fixed.
