[Boost-users] [interprocess] Mutex on mac x86 fails

7 Mar 2007

      I'm trying to run the following program, which works under Linux, on an 
intel
mac:

#include <boost/interprocess/sync/named_condition.hpp>
#include <boost/interprocess/sync/named_mutex.hpp>
#include <boost/interprocess/sync/scoped_lock.hpp>
#include <iostream>

using namespace std;
namespace bi = boost::interprocess;

int main( int argc, char **argv )
{
   cout << "Creating mutex" << endl;
try
{
   bi::named_mutex directoryMutex( bi::create_only, 
"MyVeryUniquelyNamedMutex" );
   cout << "Creating scoped lock" << endl;
   bi::scoped_lock<bi::named_mutex> lock( directoryMutex );
   cout << "All reqs met.  Destroying mutex" << endl;
   bi::named_mutex::remove( "MyVeryUniquelyNamedMutex" );
}
catch( std::exception &e )
{
   cout << "Problem encountered: " << e.what() << endl;
}

   return 0;
}

I'm using a combination of the boost CVS for the interprocess header 
files and
everything else from 1.33.1.  The interprocess headers are current as of 
Mar 7.
I've also tried open_or_create, and get the same result.

On linux, this seems to work fine, with output:
$ ./test
Creating mutex
Unlocking mutex
Creating scoped lock
All reqs met.  Destroying mutex
$

On the mac, it outputs:
$ ./test
Creating mutex
Problem encountered:
