[vtkusers] Building VTK against OSMesa causes syntax errors.

[Magnus Elden]

I am trying to build VTK with OSMesa instead of QT using Cmake 3.5.2 and
Windows 10.

 

I downloaded the source from http://www.mesa3d.org/download.html and
compiled it using SCons.

I followed the guide
http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D#Configuring_ParaV
iew_for_use_with_OSMesa and it generated just fine.

 

When I build Visual Studio complains about syntax errors:

I am using Visual Studio 2015 and I have no idea what typedef OSMesaContext
GLAPIENTRY (*OSMesaCreateContextAttribs_func)( const int *attribList,
OSMesaContext sharelist ); actually does, so I am at a loss as to what the
problem is.

The only other potential problem is the fact that I did not have the file
libosmesa.lib. I only had osmesa.lib. Not sure if that will cause a problem
or what the difference is.

 

Thank you for your help.

Yours,

Magnus Elden
