Right. So in Wayland mode, no X11?

Mederim commented 2 years ago

Yeah only wayland support

~ $ echo $XDG_SESSION_TYPE
wayland

I had a problem with this in freeglut but i used -DEGL_NO_X11 in my ~/.profile but not worked in glew:

This branch seems to work for me: PR #341 Could you give that a try?

Yes, you'll still need to link OpenGL. Perhaps -lOpenGL instead of -lGL ?

Installed libglvnd and put -lOpenGL thats worked:

@nigels-com but why not link with GLES instead of OpenGL like Freeglut?

nigels-com commented 2 years ago

ES is not supported.

Mederim commented 2 years ago

Will be in future?

nigels-com commented 2 years ago

No plans.
