[omniORB] Re: omniORB and fork()

[Stewart Gebbie]

Hi,

Thanks for the reply. I eventually found some references in the
omniorb-list archives (April 2000). It seems that I had not 
explicitly linked against -lpthread. Without this the ORB simply 
exits. The moment all the progs are explicitly linked with
-lpthread every thing works fine.
