I think you are trying to build a cross-native, see http://crosstool-ng.github.io/docs/toolchain-types/ Canadian-Cross is something like building a GCC compiler on Linux/x86_64, which runs on Cygwin/x86_64 and compiles code for Linux/ppc. > I put this flag into CFLAGS and CXXFLAGS. The first question: is that > the right place for it? No, it seems not. The right thing to do is to set CC/CXX in the configure step and append your specific CFLAGS/CXXFLAGS to it. I tested (build-only) this with OpenADK building a cross-native for Linux/xtensa. I needed to fix my package/gcc/Makefile for this, see: https://gogs.waldemar-brodkorb.de/linux/openadk/commit/e7383dee0c3fc20a2752b13f21d0bb3f5988aad6 best regards Waldemar
