Hi,
I've written my first boost::thread application, and I
get this assertion:
/boost_1_33_1/libs/thread/src/thread.cpp:223: void
boost::thread::join(): Assertion 'm_joinable' failed.
I call the thread as:
void _pollMode( Controller& ctrl ) {
// do polling ... for my testing, left blank
}
void SomeClass::startPolling() {
m_pCtrl = new Controller;
boost::function funcPoll;
funcPoll = &_pollMode;
m_thr = new boost:thread(boost::bind( funcPoll,
*m_pCtrl));
// never get past this line (unless copy ctor
modified)
}
The Controller class has a copy constructor defined,
which gets called several times (by the thread class?)
Controller( const Controller& ctrl ) {
boost::mutex::scoped_lock lock( m_mutex );
m_thr = ctrl.m_thr; // bad ??
BUT ... if I do m_thr = NULL; then everything is
ok. Why??? What's going on here???
}
Any help/explanation would be appreciated.
Rob
