❓ Questions and Help

Hello all; I was getting following error while running : python setup.py install --headless

-- Could NOT find EGL (missing: EGL_INCLUDE_DIR) CMake Error at deps/magnum/src/Magnum/Platform/CMakeLists.txt:796 (message): EGL library, required by some contexts, was not found. Set WITH_*APPLICATION and/or WITH_EGLCONTEXT to OFF to skip building them. -- Configuring incomplete, errors occurred!

Then I tried solution given in: https://github.com/facebookresearch/habitat-sim/issues/256 Hence, installed libgl1-mesa-dev and libegl1-mesa-dev sudo apt-get install libgl1-mesa-dev sudo apt-get install libegl1-mesa-dev

Now, I got following error while running python examples/example.py:

Can anyone please help me resolve this error.

Hi @KenaHemnani I had the same problem. In my case, I was configuring the server from scratch (to run the habitat).

STEPS TO REPRODUCE: I installed the nvidia-driver and cuda first. Then I installed the habitat dependencies listed here by running:

sudo apt-get update || true
# These are fairly ubiquitous packages and your system likely has them already,
# but if not, let's get the essentials for EGL support:
sudo apt-get install -y --no-install-recommends \
     libjpeg-dev libglm-dev libgl1-mesa-glx libegl1-mesa-dev mesa-utils xorg-dev freeglut3-dev

And got the same error message as you attached above.

The root cause is:

Note: Installing Mesa may overwrite the /usr/lib/libGL.so that was previously installed by the NVIDIA driver, so a reinstallation of the NVIDIA driver might be required after installing these libraries.

Source: cuda installation guide.

SOLUTION: reinstallation of the NVIDIA driver solved the issue for me.

Hi there, I came across the same problem, and I found a more convenient solution by reinstalling libglvnd. I solved the problem by running (on CentOS7):

sudo yum reinstall libglvnd

Looks like this is resolved.
