Hello!
I have been trying to install NGSolve on my computer, running Debian 9. When trying to build with OCC i get the following error:

I have been able to build without OCC, and have sucessfully tested demos such as poisson and navierstokes using the netgen commando. However the installation fails the tests run when running
make test_ngsolve
I suspect that this can have something to do with running NGSolve modules using python3 instead of the netgen gui, but i am not sure about this.
I would be greatful for any help!
