Compilation Error, undefined reference to `pthread_atfork'

Vas_M_ — Fri, 17 Feb 2006 17:43:22 GMT

I have a program that compiles in ia32 proccessor but when I'm trying to migrate to x86_64 I get the following error:
/opt/intel/ipp/5.0/em64t/sharedlib/libguide.so: undefined reference to `pthread_atfork'
I have changed all the paths to target the correct libraries and also migrated from 4.1 to 5.0, the same error occured with the previous version, but nothing has changed. Any ideas?
Thanks in advance Vas

I had a very similar problem, and resolved it by simply changing the order of included libraries. Make sure that -lpthread is listed after all IPP libraries on the link line.

The problem is that I'm not using this library at all. Soulrd I just add it?

You can at least try to, right? :)
