Hi folks, with a minor change to the crossdev script, essentially adding case ${CTARGET} in ... mmix*) KPKG="[none]"; LPKG="newlib"; STAGE_DEFAULT=${STAGE_LIBC};; ... esac I am able to bootstrap a full stage 3 cross-compiler for mmix [1,2]. Would it be possible to augment the crossdev script with above options? Two comments: * binutils and gcc are extremely picky about the arch triplet and require that one specifies exactly "mmix", no "mmix-newlib", "mmix-unknown-newlib", etc. * It need the crossdev options --without-headers as well - is it possible to set this in crossdev as default parameter as well? [1] $ crossdev --without-headers -v -t mmix * crossdev version: 20151026 * Host Portage ARCH: amd64 * Target Portage ARCH: * * Target System: mmix * Stage: 3 (C compiler & libc) * ABIs: default * binutils: binutils-[latest] * gcc: gcc-[latest] * libc: newlib-[latest] * CROSSDEV_OVERLAY: /var/lib/crossdev * PORT_LOGDIR: /var/log/portage * PORTAGE_CONFIGROOT: * Portage flags: -v [2] $ cat hello.c #include <stdio.h> int main() { printf("Hello World\n"); return 0; } $ mmix-gcc -v hello.c Using built-in specs.
