I know that -mt and +DD64 are hard-coded in acc.jam, I think, we discussed it before. Making them features is on my list, but not as a high-priority task. Certainly, not before HP-UX/aCC6 is completely green. Of course, any help is welcome.
From the link: [John] If so then BOOST_HAS_THREADS should get turned on automatically when building in multithread-mode *only* in boost/config/suffix.hpp.
This fails to happen if I remove the hardcoded *-mt* flag and instead instruct bjam to build both sinlge and multi threaded versions of the libraries. Problems with bjam probably ? Seems like it's not passing *-mt* flag to the compiler for multi-threaded build.
Volodya can give you definitive answer. Thanks, Boris ----- Original Message ----- From: "Prashant Thakre" <prashant.thakre@gmail.com> To: <boost@lists.boost.org> Sent: Tuesday, February 27, 2007 2:12 PM Subject: Re: [boost] [thread] Patch for boost/config/platform/hpux.hpp

As John said: compiling -mt (which results in _REENTRANT and _RW_MULTI_THREAD macros being set) is the *only* way to ensure thread safety.
