It appears like gmp doesn't play nice with musl hosts? a musl target is fine allowing a cross environment to work but not a pure musl evnironment or specifying musl as the host. I created a cross compiler successfully but using the cross compiler to "recreate itself" hasn't worked when rebuilding gmp as a part of the process. It could be me, everything up to this point has been apparently but i was hoping someone could chime in and let me know if they have compiled gmp on a native musl system or if it requires a patch i missed or some gnu code? thanks, stephen On Fri, Nov 14, 2014 at 2:49 PM, stephen Turner <stephen.n.turner@...il.com> wrote: > GMP errors out with "invalid configuration 'non-pc-linux-musl' not > recognized.
