Thread: Problem building in a directory shared from Mac to Ubuntu

Problem building in a directory shared from Mac to Ubuntu

Hi,
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?

"shared" how?

AFP?

SMB/CIFS? With mount.cifs?

Using NFS?

In general I'd recommend using a local directory for builds. Most
network file protocols have ... interesting ... behaviour when it comes
to file locking, timestamps, etc.

Why are you using this approach rather than just having local build trees?

You can share the directories between Host and VM using VMware Fusion. There is no network involved.

So that, 1. I can use the data between VM and host seemlessly (the binaries will be useless, I agree, but the source code will be useful) 2. I can share the same directory across more than one VM (binaries will be useful in case two VMs are same). Like building source once and using it on multiple VMs. 3. if VM crashes, the host will have the data in-tact.
