Hello Dejan, I am trying to get http://www.ros.org/wiki/objects_of_daily_use_finder to compile using CTurtle. I first had to install libsiftfast (which went ok), but now I am having hard times with odu_finder.cpp. it seems that some types are wrongly used, but I cannot figure out what is going wrong and where: solving one error triggers others. Am I doing something wrong by trying to get it to compile with Cturtle? Did I check out a wrong version? I am enclosing the trace with this message: http://ros-users.122217.n3.nabble.com/file/n2424994/trace.txt trace.txt Would you have any idea of what is going wrong? thanks in advance for your help Raph -- View this message in context: http://ros-users.122217.n3.nabble.com/Object-recognition-positioning-package-tp2399294p2424994.html Sent from the ROS-Users mailing list archive at Nabble.com.
