Unable to integrate with Qt.
I am trying to implement Grid based FAST SLAM in ROS. I have taken the source code from http://openslam.org/gridslam.html .
I have made a catkin package and put all the source code in src folder. Now, I am trying to build that package using $catkin_make
It is giving me the error: qapplication.h No such file or directory.
I have qt4 installed already and have qapplication.h file at /usr/include/qt4/Qt
I have tried using .pro file and qmake but still its giving me the error. what should I do please help...
