I do have libqt4-opengl and libqt4-opengl-dev installed, although

$ ls /usr/lib/libQtOpenGL.so
ls: cannot access /usr/lib/libQtOpenGL.so: No such file or directory

Hi,

I think I have found where this bug comes from. It also happens in my branch build of Seg3D

$ ./build.sh --seg3d-only

checking for OpenGL headers... found in /usr/include
checking for GL/gl.h... yes
checking GL/glu.h usability... yes
checking GL/glu.h presence... yes
checking for GL/glu.h... yes
checking for -lGL... no
checking for -lMesaGL... no
configure: error: OpenGL libraries not available

***ERROR in build script
The failed command was:
./configure --with-gtk --with-opengl --disable-shared --prefix=/home/ramc/secure_data/comlab/SCIRun.branch.seg3d_spline_tool/bin


This bug has been reported in wxWidgets, "OpenGL libs not located by 'configure' in debian testing"

http://trac.wxwidgets.org/ticket/13376
http://trac.wxwidgets.org/ticket/13375

The reason is that the OpenGL libraries have been moved to architecture-dependent directories, e.g. in my system

/usr/lib/x86_64-linux-gnu/libQtOpenGL.so

Best regards,

Ramon.
