Hi, We're planning to port an application to HP-UX 11i (v1 & v2) using gcc 3.2 and the implementation uses Posix threads. Here is a statement from GCC website that I need some clarification with: ------------------------------------------------------------------------ Thread support is not implemented in GCC 3.0 through 3.2, so the --enable-threads configure option does not work. In 3.3 and later, POSIX threads are supported. http://gcc.gnu.org/install/specific.html#hppa-hp-hpux ------------------------------------------------------------------------- Does it mean - gcc itself cannot use pthreads in the 3.2 version, so gcc itself is a single-threaded program OR - gcc cannot correctly build code which uses pthreads ? Please clarify. Thanks in Advance! Sincerely, Jayaram.
