I am observing a strange problem when I build latest PostgreSQL head on Ubuntu 12.04. I am running Ubuntu 12.04 as VM on Mac 10.7. The build directory points to a sub-directory of host directory shared from Mac to Ubuntu 12.04. The source is also located in a sub-directory of the shared directory.
postmaster builds without any error, but all the binaries in src/bin fail to link with error "undefined reference to `pthread_sigmask'". If I add -pthread to the link command the binaries link without error.
If I build it on a directory local to VM and also place my source in a directory local to VM, the build goes fine.
Is this a known issue? What's the cure?
