I was trying to build cmake, as I figured it would be useful for self-hosting, but in the link phase, it fails with an undefined reference to pthread_barrier_destroy(), along with a few other BSD incompatibilities.
The "pthread_barrier" functions are used by libuv, not cmake directly, so I made port files for each, as well as a custom target.mk, but I'm not sure what to do about these BSD features.
Specifically, here's what I've seen is missing: -pthread_barrier init(), wait(), and destroy() -some BSD sysctl() items related to resource usage info -a sysctl() to access the program's executable binary from itself
Most of the calls are in "src/unix/freebsd.c" and "src/unix/kqueue.c".
I wrote an implementation of the pthread_barrier functions that uses Genode::Blockade as a barrier, and I think the resource sysctl()'s can be implemented with Pd_session's ram quota functions, but I figured I should ask.
