[vtk-developers] OSMesa regression

[Bill Lorensen]

More information...

This build uses off screen rendering with os mesa. The system has qt installed.

Originally I had these settings. Worked OK until the git bisect commit.
VTK_BUILD_ALL_MODULES:BOOL=ON
VTK_USE_OFFSCREEN:BOOL=ON
VTK_OPENGL_HAS_OSMESA:BOOL=ON
VTK_USE_X:BOOL=ON

Then I changed to the following:
VTK_BUILD_ALL_MODULES:BOOL=OFF
VTK_USE_OFFSCREEN:BOOL=ON
VTK_OPENGL_HAS_OSMESA:BOOL=ON
VTK_USE_X:BOOL=OFF
VTK_Group_Imaging:BOOL=ON
VTK_Group_Qt:BOOL=OFF
VTK_Group_Rendering:BOOL=ON
VTK_Group_StandAlone:BOOL=ON
VTK_Group_Views:BOOL=ON

So the referenced commit is still a regression, but I can workaround it.

Bill
