Thanks for the head ups, I just wasn’t aware of this. Since the port llvm installs a 9.something version of llvm I guess I also can use llvm13 for instance here, right?

Do such rebuilds get triggered automatically? Or is there somebody, whom I should contact for this?

I thought that with FreeBSD 13 the RISC-V architecture moved to Tier-2 support ( https://wiki.freebsd.org/riscv#Current_Status ). Doesn’t that mean that there should be such ports available for RISC-V?

Thanks for reporting this! Hopefully they fix it soon.

I just used what was in the GNUstep repo and tweaked it a bit for the modern times. Since GNUstep is written mostly in Objective-C, I guess I need a LLVM which supports this too, hence the package requirement I would say. But I am not sure …

While this was mainly a no-brainer for Linux-Fedora/RISC-V (some minor tweaks were necessary), it seems on the FreeBSD side are some more serious efforts necessary. I think this will not be my last E-Mail in this regard to the list. Hope you can stand this!
