That is a much simpler and clearer explanation than most of the docs on Canadian cross I've seen. Because I can run both the host and target compilers on my build machine, some of the nuances of the cross are hidden that might have been obvious to me otherwise :-) I was just thinking we would use the xgcc to build the target libraries, but that obviously won't work in a REAL cross since that xgcc runs on the host. OK, got it. So next question: I want my final toolchain to including C, C++, and FORTRAN compilers. I was thinking that I would need only C and C++ for the build-x-host and build-x-target compilers, but the configure of the final GCC fails since it can't find NEWSYS-gfortran. So I guess I need all three, at least for the build-x-target compiler? Are some of the FORTRAN libraries written themselves in FORTRAN?
