compiler error on using threads with boost
Hi, I get this compiler error : boost/thread/future.hpp", line 414: Error: Formal argument other of type boost::unique_lock<boost::mutex> in call to boost::unique_lock<boost::mutex>::operator=(boost::unique_lock<boost::mutex>) has an inaccessible copy constructor. Any idea why this is? I'm using the sun compiler to compile it with Regards, iskandar

Additionally, you can move the unique_lock to transfer the ownership. Regards, Ovanes On Mon, Mar 29, 2010 at 3:46 PM, Ovanes Markarian <om_boost@keywallet.com>wrote:

Which compiler (+version) and boost version do you use? On my MacOS X g++ 4.01 and boost 1.42 your example compiles without errors.

I'll volunteer for... what's the opposite of "Champion"? :-) Sun Studio is a rather poor C++ compiler. GCC is the better choice for C++ on Solaris.
