pylon_camera catkin_make error

edit

I installed a ROS-Driver for Basler Cameras accordance with the tutorial in http://wiki.ros.org/pylon_camera

But when catkin_make I met these problems:

compilation terminated.
make[2]: *** [pylon_camera/CMakeFiles/pylon_camera.dir/src/pylon_camera/pylon_camera.cpp.o] Error 1
make[2]: *** Waiting for unfinished jobs....

                           ^

Who knows how to solve these problems? Thank you very much!
