Apparently, -ccbin and --compiler-bindir can't both be set. The following patch solves the problem for me: --- nvidia-cuda-sdk-6.5.14.ebuild 2014-09-19 06:53:57.118470681 +0800 +++ nvidia-cuda-sdk-6.5.14.ebuild 2014-09-19 06:56:11.958603140 +0800 @@ -55,6 +55,7 @@ export RAWLDFLAGS="$(raw-ldflags)" # epatch "${FILESDIR}"/${P}-asneeded.patch + NVCCFLAGS="$(echo "$NVCCFLAGS" | sed -e 's:--compiler-bindir=[^ ]*::')" sed \ -e 's:-O2::g' \ -e 's:-O3::g' \
Thanks for the report. But I think we need to remove ccbin as it will break otherwise with gcc-4.9. But I will look into it.
