Answered my own question. I needed to link to pthread in these applications. The link error confused me in that I thought pthread was being linked to and was the component making the undefined reference. Guess not....

I'm running Mandrake linux v10.0 offical release.

I've developed a problem recently in linking cpp applications that use shared libraries.
This may have been caused by:
  a.  upgrading to gcc v3.4.3 from v3.4.2, or
  b.  rebuilding my linux system.
In multiple applications, I get: /lib/tls/libpthread.so.0: undefined reference to `errno@GLIBC_PRIVATE' /lib/tls/libpthread.so.0: undefined reference to `__libc_dl_error_tsd@GLIBC_PRIVATE'

In the past, I didn't need to explicitly link to libc.so, I assume that it auto-linked as needed. Now it doesn't matter if I link to it or not.

Can someone point of the cause of this error?
