How can I fix a build error?

Hi, this worked for me:

9.0.0.rc1 ContextOpenGL2 not built

Hm okay. I just tested with curl -LO https://www.vtk.org/files/release/9.0/VTK-9.0.1.tar.gz tar xf VTK-9.0.1.tar.gz cd VTK-9.0.1/ mkdir build cd build cmake -DVTK_MODULE_ENABLE_VTK_RenderingContextOpenGL2=YES .. and I’m not getting that warning here. Full transcript here: transcript.txt (30.0 KB) Maybe it has something to with what groups/modules get enabled by default on your system. Would help to see the output from the CMake run.
