Hi I built both boost.1.3.2 and boost 1.3.9 in the hpux 11.23 system. I can see the pthread_create symbol in boost 1.3.2 library

Could you clarify what exactly you see in what file and how do you see that?

but not in boost1.3.9 thread library. Due to this issue, my application crashing hpux 11.11 with boost 1.3.9 system and showing message "pthead_create symbol not found" in the boost thread library but working fine with 1.3.2.

pthread_create is part of libpthread, which is part of system libraries. You should link to that. - Volodya
