[vtkusers] vtkQGL, editing source code required?

[George Kamucha]

Hi Fabian,
I downloaded vtk 3.1.2, compiled it and that did part of the trick, the installation of the
vtkQGL31 sources was successful! But I have spent the last 26 hours or so trying to figure out why
the compilation fails in the examples' directory. I am at my wits' ends and please if you have an
idea about this error, please let me know, I will really appreciate. I am using qt 2.1.0 and I had
thought I had set all the paths properly but something is definitely not right. Here is one of the
the error messages I am getting:

make[1]: Entering directory '/home/kamucha/vtkQGL31/examples'
g++ -o simpleTest simpleTest.o -L../lib -L/usr/lib/qt/lib -L/home/kamucha/vtk312unix/vtk31/../lib
-L/usr/X11R6/lib

Best regards
