Hi Ion, This thread from Feb 2004 may be helpful: http://lists.apple.com/archives/Darwin-development/2004/Feb/ msg00146.html "Darwin's pthreads implementation does not support the optional "Thread Process-Shared Synchronization" functionality, so calling pthread_mutexattr_setpshared() with the PTHREAD_PROCESS_SHARED attribute will return EINVAL." Darwin is the BSD-ish underbelly of Mac OS X, so it's not glibc but Apple supplied. I'm using Mac OS X version 10.4.5, so this is the most up to date darwin. -Ian On Apr 13, 2006, at 4:34 AM, Ion Gaztañaga wrote:
Hi Ian,
Thanks for pointing out this. In the future, Shmem is becoming Interprocess so I plan to use Boost.Date_Time instead of my own time functions.
With this patch, I am able to get the examples in shmem to build. Unfortunately, it then fails in boost::shmem::detail::mutexattr_wrapper::mutexattr_wrapper because pthread_mutexattr_init fails.
That might suggest that your darwin version does not support process shared mutexes. I'm sorry I don't check that explicitly in my config headers (I'm lost in all those POSIX option checkings).
Maybe you need to update your c library (darwin uses glibc or similar?) to get both gettime and process shared mutexes. I will try to implement some basic tests for future bugfix Shmem versions.
Regards,
Ion
