Attach your config.log and check if the lib provides the symbol.

Symbol Table

First, avahi-client!=avahi-common
Well, as the errors clearly show, the problem lies with avahi
- it doesn't link avahi-common with pthread.
Do you have its build log ?

ah, sorry. I misunderstood what you wanted. I assumed you were referring to avahi-common symbol table since that's where the configure check failed.

Anyway, I know what the problem is. I don't know why I didn't recognize it earlier. Your comment about pthreads clued me in.

I had been experimenting a few weeks back with openmp and seeing if any kind of benefits could be gained on SMP machines when building a system with openmp.

I don't know what the problem is, but apparently this is a nasty bug somewhere; not really sure if it's with the compiler, linker, openmp, or even perhaps even something else. But apparently quite a few packages don't link against pthreads like they should when built with the -fopenmp build flag set. They DO work when you set BOTH -fopenmp and -lpthreads explicitly.


I thought I had gone back and rebuilt everything that I originally compiled with -fopenmp, but apparently I missed avahi. Recompiled avahi, and now samba doesn't have any issues configuring.

You will probably want to mark this as a duplicate of 323505 where I originally figured out what was going on and where other maintainers are still trying to figure out how to deal with this issue.

And I just realized you were the one who initially responded to that one too... :P

silly openmp :)
