I successfully compiled ElasticFusion on Ubuntu 20.04. However, when running "./ElasticFusion -l ../dyson_lab.klg", there was error as follows:

GLSL Program link failed: error: vertex shader lacks `main'

How to fix above problem? Thanks in advanced.

Can you run the Pangolin examples without issues? This might just be an issues with the shaders of Elastic Fusion.

Now I have fixed this issue. I used "sudo prime-select nvidia" CLI to make sure that running ElasticFusion on nVidia GPU. Moreover, one can check it by "glxinfo | grep OpenGL" CLI.

Thinks a lots!
