--- Comment #4 from Brett Neumeier <bneumeier at gmail dot com> --- Created attachment 43324 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43324&action=edit Patch to add rpath for GMP, MPC, MPFR, ISL when needed OK. I'm just going to leave this patch here -- tested and verified to resolve my issues I'm having -- for anyone else who runs across this problem and happens to check the gcc bugzilla to see if it's a known problem. I was interested to see that the GMP, MPC, MPFR, and ISL configure scripts all have logic to add RPATHs as well, although the logic there is a good deal more complicated than this. So at least I'm in good company thinking it's The Right Thing to do. Cheers!
