Below is a listing of the procedure I used to build a linux hosted h8/300 toolchain for development with the hitachi H8/3644F processor (HD64F3644). It's very likely I didn't use the canonical or most efficient method to do this, I'd appreciate comments. Also note the error on building libf2c during the cross build, shouldn't libf2c have been excluded from the config in a cross build --with-newlib and LANGUAGES set to "c c++" ??? Lastly, the compiler seems to run ok, but there's a problem with the linker giving me "Segmentation fault (core dumped)" whenever I attempt to include a library or archive file with my link. i.e. by adding -lc to linker command line, or INPUT(anything.a) to the linker command script. Any ideas for the cause of that? -- |\/| |/\| randall@elgar.com |\/| rsl@zanshinsys.com http://www.zanshinsys.com
