[vtkusers] RE: vtkqt linking errors

[Rupert Shute]

Jianlong,
	Removing 'VTK_RENDERING_EXPORT' from vtkQGLLight.h seems to do the
trick. What the wider implications of this are I have no idea! But for now
my code seems to work ok.

Hope this works for you too,

Regards

Rupert

Hi, Rupert,

I also have these problems. I tried several versions of vtkqt library, they
are same. I have 
not got a solution yet. If you have some ideas, kindly hope to tell me.

Best regards,

Jianlong
