Hi ,

I removed ibqglviewer-qt3-dev .
and  libqglviewer-dev-common ,  libqglviewer-qt4-dev  , libqglviewer-qt4.2  was installed before .

also libcgal7 and libcgal-demo , libcgal-dev , libcgal-ipletes are installed too.

I see demo window but it is white and contain nothing. It ends with 4 warning in terminal.

this is my terminal . I did not forgot to change my CGAL path to /home/sara/CGAL-4.1
this is in release mode : but there is not any change in Debug mode too.

I want to say you that I have run one of demo named "Surface_reconstruction_points_3" successfully .

Thanks for the report. Now I understand. It seems that the FindQGLViewer CMake
module found the Qt3 version of libqglviewer, instead of the Qt4 one.

Please install the package named "libqglviewer-qt4-dev", and *uninstall* the
package "libqglviewer-qt3-dev".
