I am attempting to specify a host compiler via the file ~/.ptxdist/ptxdistrc-2015.02 PTXCONF_SETUP_HOST_CPP="cpp-4.8" PTXCONF_SETUP_HOST_CC="gcc-4.8" PTXCONF_SETUP_HOST_CXX="g++-4.8" PTXCONF_SETUP_HOST_MAKE="make" I think this is ptxdist setup developer options. I expected ptxdist to use these compilers to build host-* packages, but instead it is using gcc and g++. I'm including a patch which behaves more the way I expect below. Would you guys care to comment on how I should have done this? I would like to build my firmware on different ubuntu versions which come with different compilers.
