When I building my paraview, the following errors happened, I can’t solve it. Anybody else have met the similar errors? Could you give me some suggestions? Thank you very much.

Against which version of Qt are you building ParaView?

Did you build Qt yourself ?

You are impacted by this bug :  
[https://gitlab.kitware.com/paraview/paraview-superbuild/issues/94](https://gitlab.kitware.com/paraview/paraview-superbuild/issues/94)

You can either rebuild qt with `-opengl dynamic` or simply download a qt package and install it to build ParaView with.

Unless you have specific needs, I would suggest the later.
