I added the trivial bits to build-many-glibcs.py for supporting ARC, but it seems there are some roadblocks. 1. There are still some in-flight patches for gcc/binutils upstreaming. The latest working versions are hoisted on on SNPS github portal, but that won't fly I guess. Anyhow for now, the upstream versions are likely to suffice for say building part. 2. The immediate (and embarrassing) issue is trying to figure out how to make the build-many-glibcs.py script work. A wiki page for new ports would have helped a lot. - How do I call it the first time, with my existing version of glibc. The checkout process, gets upstream glibc and tries to build that instead. - So I created a src directory manually, will all other tools and glibc being a symlink to my existing glibc tree and calling it as follows $ test-glibc/src/glibc>./scripts/build-many-glibcs.py <abs-path>/test-glibc compilers arc-linux-gnu FAIL: compilers-arc-linux-gnu check-host-libraries UNRESOLVED: compilers-arc-linux-gnu binutils rm UNRESOLVED: compilers-arc-linux-gnu binutils mkdir UNRESOLVED: compilers-arc-linux-gnu binutils configure UNRESOLVED: compilers-arc-linux-gnu binutils build ... I'm missing obvious/simple stuff, but this is a new env for me. -Vineet
