The OpenGL backend for Makie
Please file all issues in Makie.jl, and mention GLMakie in the issue text!
If you get any error loading GLMakie, it likely means, you don't have an OpenGL capable Graphic Card, or you don't have an OpenGL 3.3 capable video driver installed. Note, that most GPUs, even 8 year old integrated ones, support OpenGL 3.3.
On Linux, you can find out your OpenGL version with:
glxinfo | grep "OpenGL version"
If you're using an AMD or Intel gpu on linux, you may run into GLFW#198.
If you're on a headless server, you still need to install x-server and proper graphics drivers.
You can find instructions to set that up in:
https://nextjournal.com/sdanisch/GLMakie-nogpu And for a headless github action:
If none of these work for you, there is also a Cairo and WebGL backend for Makie which you can use:
If you get an error pointing to GLFW.jl, please look into the existing GLFW issues, and also google for those errors. This is then very likely something that needs fixing in the glfw c library or in the GPU drivers.
WGL setup or X-forwarding
WSL runs OpenGL alright, but it is not a supported scenario. From a clean Ubuntu install from the store do:
sudo apt install ubuntu-desktop mesa-utils export DISPLAY=localhost:0 glxgears
On the Windows side:
- install VcXsrv
- choose multiple windows -> display 0 -> start no client -> disable native opengl
sudo apt-get install -y xorg-dev mesa-utils xvfb libgl1 freeglut3-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libxext-dev
2.) WSL has some problems with passing through localhost, so one may need to use:
export DISPLAY=192.168.178.31:0, with the local ip of the pcs network adapter, which runs VcXsrv
3.) One may need
mv /opt/julia-1.5.2/lib/julia/libstdc++.so.6 /opt/julia-1.5.2/lib/julia/libcpp.backup, another form of GLFW#198
