I am trying to implement Grid based FAST SLAM in ROS. I have taken the source code from .

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...

write the following lines in your Cmake

find_package(Qt4 COMPONENTS QtCore QtGui)
rosbuild_add_executable(qt_test src/qt_test.cpp)
target_link_libraries(qt_test ${QT_LIBRARIES})

also please see this question

but instead of rosbuild_add_executable(qt_test src/qt_test.cpp) add_executable(qt_test src/qt_test.cpp) worked for me.. Thanx :)

rosbuild_add_executable for rosbuild system and add_executable for catkin. I made mistake that I thought you worked with rosbuild system...

I would start by googling about using Qt in catkin. For exmaple this turns up (have not checked if it is good):
