Compiling on mac with MPI and GUI

Hello,

I had a few errors when compiling the latest version from sources on a Mac(currently I am running Mojave 10.14.2) with MPI and GUI enabled. I managed to compile the serial code and also the parallel one without GUI. I am getting the errors in the file
ngsolve-src/external_dependencies/netgen/libsrc/visualization/mvdraw.cpp

Some features are either deprecated or somehow different. I am also attaching an image with all the generated 7 errors.

Some help on this would be great!

Thanks in advance!

MPI + GUI is not supposed to work.

The combination worked in the past, but never at a large scale. It used parallel OpenGL display list features, which are not supported anymore.

You can save a GridFunction living on the distributed mesh, and load it into a sequential run for visualization. Streaming via pickling should work in near future.
