Is there a patch for "thread copy constructor is accessible" BUG in solaris.
Hi , I had posted this in build list now I am posting this in users of boost list. Please help thanks in advance. -------- I have done the temporary fix to build the boost 1.37.0 as told in one of the solaris user forum thread http://forums.sun.com/thread.jspa?threadID=5326640 http://forums.sun.com/thread.jspa?threadID=5326640 for the below said error sun.compile.c++ bin.v2/libs/thread/build/sun-5.9/release/link-static/threading-multi/thr ead.o "./boost/thread/detail/thread.hpp", line 344: Error, inaccessible: boost::thread::thread(boost::thread&) is not accessible from boost::move(boost::detail::thread_move_tboost::thread). 1 Error(s) detected. Do I need a patch to fix this? -PM-

Yes, but not the one suggested. That constructor is private for a reason, and does not actually exist. It is a bug in the compiler that requires it to exist, since it should not be chosen for copying a temporary. If the optimization setting is low enough that the compiler tries to call it then you'll get a link error. I change the move function for thread from boost 1.35 in order to fix an issue with gcc. I'll see what I can come up with. Please raise a trac ticket so I don't forget, as I'm rather snowed under right now.

Anthony,
Could you please tell me what should be the fix in the "move" method?
Since you have already done that for 1.35.

In Boost 1.35, the move method just returned the boost::detail::thread_move_tboost::thread passed in. This is actually closer to the rvalue-reference case from C++0x, but caused problems in some cases on gcc.
