Ardour fails to build in directory libs/pbd with the error: pthread_utils.cc: In function `void pthread_kill_all(int)': pthread_utils.cc:73: error: `pthread_kill' undeclared (first use this function) pthread_utils.cc:73: error: (Each undeclared identifier is reported only once for each function it appears in.) pthread_kill is declared through signal.h, which was not included. I added #include <signal.h> to pthread_utils.cc. The patch is attached. Reproducible: Always Steps to Reproduce: 1. Run emerge ardour 2. 3. Actual Results: The above error. Expected Results: Built and installed ardour I am using glibc 2.3.2-r8 with nptl support.

Created attachment 20488 [details, diff] Add #include <signal.h> to libs/pbd/pbd/pthread_utils.h I successfully used this to build ardour on my system. Ardour crashs a bit, but I think that is other bugs, not the patch.
