I would only count on base GCC for C and C++. It should do Objective-C, but as someone who has never written that, I couldn't get it to not-crash.
regular pkgsrc GCC has most of the other languages: Fortran: default enabled Ada: separate package (gcc5-aux), as it requires binary bootstrap Java: older GCC Go: default disabled in pkgsrc GCC, as an option D: only available since GCC 9, and I only did amd64, might need to separately work on i386. GCC 9 is not a package yet, I put a snapshot in wip at the time though.
