ERROR: Unable to initialize EGL

See original GitHub issue

Hi team, thank you for maintaining this project.

My iGibson installation went fine, but I am facing an issue that seems common among many iGibson beginners.

(igib) ➜  ~ python -m igibson.examples.environments.env_nonint_example

I went through all the closed issues related to this, but nothing helped. I also went through the troubleshooting guide and things seemed fine to me. Here are the outputs of some commands I ran to check the EGL installation:

(igib) ➜  ~ ldconfig -p | grep EGL
  libEGL_nvidia.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.0

Reinstalling after USE_GLAD set to FALSE didn’t work either.

Thanks!

I was able to resolve this issue by downgrading my NVIDIA GPU driver from 510 to 470 😄 Therefore, closing this.

@WJJLBJ Hi, I encountered the same issue as you mentioned about the egl problem when using ubuntu 18.04. But then I found in Google that there is not ligegl-dev for ubuntu18.04, so I upgraded the system to 20.04. Then it finally works. And I also recommend you to install ros-noetic because ros would help you fix many egl dependency issues.
