Thread: [pgagent] patch: link with -pthread

All non-x868 architectures need -pthread to link with threads:

Hi Dave,

Sure. 

I can see below warning during linking in windows.

========== Rebuild All: 2 succeeded, 0 failed, 0 skipped ==========

Is this only required in case of linux right ? I can work on this - Should we skip linking in case of Mac and windows ?

Thanks

That throws a nice warning on macOS (unused-command-line-argument) as I suspected it might. I'll bet Windows barfs on it too.

Neel, can you look and see what is the best solution here please? I'm guessing you still have build environments for all platforms from the Boost work you did.

Thanks.

It's needed on non-x86 Linux, but does not complain on x86 (and I
think it's good style to use it there as well).
