Re: Linker failing with gcc10

Is there a way to get the linker to stop looking for libgcc_s?

The GCC packages have some weird libgcc handling to try and work around issues on NetBSD. I strongly recommend you always build with the "always-libgcc" option enabled to avoid this.

Without this option enabled, the libgcc_s files are deleted from the package, which is precisely why you're hitting this problem.

The easiest way to do this is by adding this to mk.conf:

  PKG_DEFAULT_OPTIONS+= always-libgcc

however you will need to completely rebuild lang/gcc10 again, sorry.
