Subj : Re: compiling for pthreads on AIX 5.2L To : comp.programming.threads From : fred Date : Tue Mar 08 2005 08:29 am ok, to follow up on myself, once more, the solution (workaround??) is to add -D_POSIX_SOURCE to CFLAGS. You'd think this would happen automatically if, as the document mentioned above says, all you need is -pthread. Oh well, at least I'm on the road now. Thanks for your patience! Fred .
