Please could you check if the following works in your configuration?

boost::move(locks[i]=boost::unique_lock<boost::mutex>(futures[i].future->mutex));

cc viboes removed
milestone To Be Determined → Boost 1.49.0

In order to state clearly that this is a workaround I will use instead

#if defined __DECCXX || defined __SUNPRO_CC
                        locks[i]=boost::unique_lock<boost::mutex>(futures[i].future->mutex).move();
#else
                        locks[i]=boost::unique_lock<boost::mutex>(futures[i].future->mutex);
#endif

Let me know if this works for you.

Committed in trunk revision 75788.

Yeah, it compiles with this workaround.

Is this a good workaround?

You could also change the visibility of unique_lock& operator=(unique_lock&) in boost/thread/locks.hpp to public.

I think the root of problem has something to do that the sun compiler does not support rvalue references. The define BOOST_NO_RVALUE_REFERENCES is set in boost/config/compiler/sunpro_cc.hpp.

Please could you open another ticket for the visibility?
