  • #145346 | 2012-10-18 03:25:12, *0 | <diverdude@#c++> I have 2 threads A and B, A is main thread and B is a worker, I need to block thread B so that it sleeps until thread A sends a signal/event ? thread B then does its work, and on signal/event from threadA, thread B should block again. I implemented it in this short code: http://... and it seems to work correct. Do you guys think what i am doing is sane and looks ok? or did i screw up?

  • #121345 | 2012-08-07 17:44:09, *0 | <diverdude@#c++> I have this setup: http://... where main function is in main.cpp, and i have most includes in basis.h. When i compile this i get an error saying that: glcm.h:7:57: error: expected template-name before < token I dont understand this since it compiled fine when everything was in a single file.

  • #118824 | 2012-08-01 03:58:39, *0 | <diverdude@#c++> I am adding elements to an internal vector like in this method: http://... like this: Im.addGLCM(0,1).addGLCM(0,-1).addGLCM(1,0).addGLCM(-1,0).addGLCM(-1,-1); The thing is that after this line, instead of having 5 objects in the vector there is only 1. I think its because i am not saving the returned image object, but I dont exactly understand why. Can somebody point me in the right direction?
