[vtkusers] vtkQGL, editing source code required?

[Fabian Eilers]

Hi !!

There is a failure in the "moc-compilation". Qt uses this for their SIGNAL-SLOT-Konzept.
But I don't realize where...

Which compiler do you use ? Try another. Perhaps it works.

Try another qt-Version. I prefer qt 2.3.0, because you don't have the qgl-Library anymore.
But take a look at the attachments.

I have no other ideas. Sorry. It's "try and error".

On a SGI you must have the right order:
- the include pathes first -> I..../vtk312/common, then /graphics, then /imaging, then /contrib, then
/patented
- then the libraries in same order -> L..../vtk312/common -lVTKCommon, and so on...

I sent the Makefile of my compilation as attachment. It works.

Greetings
Fabian
