7 years ago Ugh. Thanks for the detailed report, mothringer. Excellent username as well. Because we could all use a little more Mothra.
This sadly appears to be an upstream issue. The fix is happily trivial: the src/crafting.cpp file needs to be prepended by the line #include <cmath>, at which point compilation should succeed. Completely untested. May destroy your life.
Would you mind filing an upstream issue at the C:DDA issue tracker, ideally including the same error output and this proposed solution? If not, that's cool. Time's a bit scarce on my end, however.
So it goes. ⌛️

The above referenced ebuild fails compilation for me with the error below.
