It's a little trickier than you might expect, because of libmpc, which is also linked with mpfr. We had to come up with a way to have mpfr 3, libmpc linked with mpfr 3, mpfr 4, and libmpc linked with mpfr 4 all in the build root at the same time, the former two for the existing gcc, the latter two to build the new gcc. That was the sticking point with the previous effort to move to mpfr 4, back in the F28 timeframe. My solution (which no doubt could be improved upon) was described in the 5th message of this thread, back in July: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/thread/GEZQK73LJPCF57K4DRYWNV7WZDHK53WN/ I don't understand your question about changing GCC build requirements. They're changing *back* now, to what they were before the transition began; i.e., mpfr-devel and libmpc-devel. Thanks for responding so quickly. I appreciate you fixing the gcc build and getting it restarted. I expect it will finish while I am sleeping tonight, so I'll get the rest of the builds launched first thing in the morning tomorrow. Given that we still have to get through the flint-Singular-polymake-sagemath sequence of builds, they probably won't finish until Sunday night, or possibly even Monday morning. I appreciate everybody's patience with this process.
