Include the pthread.h file before any other system files and that should fix the problem. OK, I just did that and it didn't work. But, I fixed it after that. Here's the story: - I'm running Pth 1.4.1 on Mandrake 9.0 - The libpth14-devel package _doesn't_ include libpthread stuff - I rebuilt libpth14-devel adding libpthread to it - The Pth makefile doesn't install the .a nor .so.* files -- Mandrake caught this and fixed it in the RPM for the libpth stuff - I copied the .a .so.* files to their required location after doing the make install - After all of the above mondo contained its own shutdown() function which conflicted with a system shutdown() function -- this didn't conflict until I installed Pth's pthread API stuff. - I renamed mondo's shutdown() to mondo_shutdown() and the conflict went away - Mondo built just fine after that Then I ran mondo and the non-working results looked _exactly_ like the non-working results I got when using pthreads from glibc 2.2.5.

No mutex stuff exists in mondo. The whole of the pthread code in mondo is very small, maybe 1-2 dozen pthread calls.

RE: can pthread and pth coexist
If you are doing this on Linux you can use the HARD system call method, look at the config options, which when you link will use the pthread emulation api in pth threads. -Original Message- From: Thor Tall [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 21, 2003 5:02 AM To: [EMAIL PROTECTED] Subject: can pthread and pth coexist We are using COTS library which is using pthread and a number of other libraries which we can not recompile.
