Hello, I'm trying to build a canadian cross compiler with build == x86_64-linux, host == xtensa-linux and target == xtensa-linux. I need to specify an xtensa-specific flag in CFLAGS that will be applied to the host binary.
I put this flag into CFLAGS and CXXFLAGS. The first question: is that the right place for it? The build process tries to build libcpp for the build system and it runs x86_64 gcc with that xtensa-specific option. That's where the build breaks for me, because the option is not recognized by the build gcc. Is it supposed to work? If CFLAGS/CXXFLAGS is the right place for the option, how can the build tell whether it's intended for the build or for the host? -- Thanks. -- Max
