Hi all,
I'm interested in getting boost::shared_ptr to use atomic ops on Solaris. I notice there is an implementation using the OS-provided atomics in boost/detail/sp_counted_base_solaris.hpp, but it doesn't seem to be included. According to this thread:
http://lists.boost.org/Archives/boost/2006/07/107144.php, it seems the reason might be that it wasn't possible to come up with a proper preprocessor condition to include it on the right versions of Solaris.
What implementation does your platform currently pick? There is also sp_counted_base_gcc_sparc.hpp, which does use atomic operations.
Hi Peter, On my platform (Solaris 10 on x86 with Sun Studio 12), it picks sp_counted_base_spin.hpp. Unfortunately there is no actual spinlock implementation picked for this platform either, so it ends up with a plain pthread_mutex_lock/unlock, which is not ideal. I need to stick with Studio for other reasons, so unfortunately gcc is not an option. Thanks for the response, Graham -- Graham Bennett
