Thanks you, Trang, for you reply.

The linking to libCGAL_Qt4.so is missing, in that link command line. That is 
strange. Have you compiled CGAL libraries without Qt4 support? Have you 
modified CGAL-4.1/demo/AABB_tree/CMakeLists.txt? Its normal behavior is to 
display an error if CGAL libraries are compiled without the support for Qt4.
