[GRASS-user] 3D view error on MacOS (black screen)

Hi all

I’m running 7.2.2 on MacOS Sierra, installed via homebrew. Trying to display anything in 3D results only in a black screen. Checking the console I get these error messages:

Traceback (most recent call last):

Hi Carlos,

I couldn't get 3D view working with homebrew either. The error you see
seems to happen when you click and drag in the window, so the actual
problem happens before, because it never loads. Interestingly, when I
compiled GRASS myself (using the homebrew libraries), the 3D worked.
Unfortunately I have no idea what's wrong.

Hello Anna

I managed to fixed by compiling using homebrew libraries. The trick was to set --with-opengl=aqua, so it uses the opengl librarie from the system. Using --with-opengl=x11 results in the black screen.
