Re: [Boost-users] Building Boost 1.31.1 on OpenBSD

I tried your suggestion and got this error message:

Any other suggestions? I've already set the LIBS variable to "-lpthread".

OK we're making progress (honestly!) can you please try one more patch this time to boost/platform/bsd.hpp, basically I suspect the unistd.h isn't defining _POSIX_THREADS so threading support isn't picked up on. John.
