I tried to report this issue to the user list, but I think it's still under moderation, ..and it's kind of strange error I'm getting solely by including a header like this:
#<boost/thread/thread.hpp> int main() { return 0; }
This occurs with boost version 1.48 and gcc 4.4.5 on linux
The error occurs at lines 53, 69, 88 and 94 in boost/thread/pthread/condition_variable.hpp, and the error is that 'internal_mutex' is not declared. Here below is an inline function containing the line 53.
inline void condition_variable::wait(unique_lock<mutex>& m) { int res=0; { thread_cv_detail::lock_on_exit<unique_lock<mutex> > guard; detail::interruption_checker check_for_interruption(&internal_mutex,&cond); // HERE IS THE ERROR guard.activate(m); res=pthread_cond_wait(&cond,&internal_mutex); } this_thread::interruption_point(); if(res) { boost::throw_exception(condition_error()); } }
.I can agree with the compiler, I don't see any declaration of internal_mutex, ..is this a spelling error, and if so, why am I the only one seeing this?? I can't find anyone else reporting something like this via google. Very strange… Any idea?

Hi, I don't know under which conditions you are getting this error :( The declaration is on the file boost/thread/pthread/condition_variable_fwd.hpp class condition_variable { private: pthread_mutex_t internal_mutex; // ************* Could you add #error before this declaration? Best, Vicente
