Created attachment 396566 [details] nvidia-cuda-sdk-6.5.19.ebuild Building 0_simple/simpleMPI fails due to mpicxx -v output not containing the string x86_64-pc-linux-gnu-gcc as it only contains x86_64-pc-linux-gnu and gcc as seperate strings. There was a patch to fix the issue that was removed in bug #516020 but that patch was not the proper fix. The problem is that the ebuild does a large sed command on all of the Makefiles that replaces "gcc" with the output of tc-getCC() for lines that contain "CC" which also includes lines that contain MPI_GCC. A recursive grep of the Makefiles shows that the only instance of "gcc" is in the 0_simple/simpleMPI Makefile in the line which tests mpicxx -v to see if it contains the text "gcc". I created a modified ebuild which removes the find and replace of gcc. The updated ebuild compiles on my system.

I don't know what your patch tries to accomplish. Replacing "gcc" with something better is probably the way to go. I'm pretty sure /removing/ that substitution is wrong, and I'm certain that injecting the output of tc-getCC/tc-getCXX everywhere is wrong: the replacment should be $(CC)/$(CXX) and then those variables should be set in the make environment. In fact the ebuild shouldn't inject variable values into Makefile at all.
I agree. I am proposing a better patch which provides the compiler and flags as options to make instead of injecting them into the Makefiles. It is possible to specify EXTRA_LDFLAGS in a similar way, but it fails if any of the options have commas in them (like -Wl options.) --- nvidia-cuda-sdk-6.5.19.ebuild +++ nvidia-cuda-sdk-6.5.19.ebuild @@ -68,14 +68,6 @@ sed \ -e 's:-O2::g' \ -e 's:-O3::g' \ - -e "/LINK/s:gcc:$(tc-getCC) ${LDFLAGS}:g" \ - -e "/LINK/s:g++:$(tc-getCXX) ${LDFLAGS}:g" \ - -e "/CC/s:gcc:$(tc-getCC):g" \ - -e "/GCC/s:g++:$(tc-getCXX):g" \ - -e "/NVCC /s|\(:=\).*|:= ${EPREFIX}/opt/cuda/bin/nvcc|g" \ - -e "/ CFLAGS/s|\(:=\)|\1 ${CFLAGS}|g" \ - -e "/ CXXFLAGS/s|\(:=\)|\1 ${CXXFLAGS}|g" \ - -e "/NVCCFLAGS/s|\(:=\)|\1 ${NVCCFLAGS} |g" \ -e 's:-Wimplicit::g' \ -e "s|../../common/lib/linux/\$(OS_ARCH)/libGLEW.a|$(pkg-config --libs glew)|g" \ -e "s|../../common/lib/\$(OSLOWER)/libGLEW.a|$(pkg-config --libs glew)|g" \ @@ -96,6 +88,9 @@ cuda-install="${EPREFIX}/opt/cuda" \ CUDA_PATH="${EPREFIX}/opt/cuda/" \ MPI_GCC=10 \ + GCC="$(cuda_gccdir)/$(tc-getCXX)" \ + EXTRA_NVCCFLAGS="`echo $NVCCFLAGS | sed 's/--compiler-bindir=[^ ]*//'`" \ + EXTRA_CCFLAGS="${CXXFLAGS}" \ ${myopts} ${verbose} }
