Dear Hanchuan,

Following your helpful hints, I have successfully built v3d on ubuntu by manually tweaking the Makefile with adding '-I//usr/local/Trolltech/Qt-4.7.3/demos/shared' and '-L/usr/local/Trolltech/Qt-4.7.3/demos/shared -ldemo_shared'
Future discussions will be tracked in the forum instead.
Regards,
Siqi

I got a new error complaining as below which might indicate the implementation of arthurwidgets.cpp has not been found. Is it a known issue with a solution?

Thank you Hanchuan and Siqi,

This tweak also worked nicely for me :)
Now I only have some residual errors in the compilation of some plugins.

Best regards,
Linus

Dear all,
I'm getting the exact same error messages. I build QT from Source but still getting these error messages.
Which makefile exactly did you tweak? I tried to include the folder in the .includes file but this doesn't solve the problem.
I also tried adding the path in the topmost CMAKE file but also this did not solve the issue.
I checked the example files are there, they are just not getting included.

Thanks for your help
