Unable to initialize EGL¶
It is usually caused by incorrect installation of nvidia-driver, insufficient OpenGL version, or no EGL is installed on the machine.
It is a good idea to run
ldconfig -p | grep EGL and you should be able to see
libEGL_nvidia.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.0 libEGL_nvidia.so.0 (libc6) => /usr/lib/i386-linux-gnu/libEGL_nvidia.so.0 libEGL_mesa.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0 libEGL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL.so.1 libEGL.so.1 (libc6) => /usr/lib/i386-linux-gnu/libEGL.so.1 libEGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL.so libEGL.so (libc6) => /usr/lib/i386-linux-gnu/libEGL.so
Make sure EGL is not linked to mesa, because in order for gibson to work, linking to Nvidia’s EGL is required. For example, this will cause problems:
/usr/lib/x86_64-linux-gnu/libEGL.so -> mesa-egl/libEGL.so
If the original installation doesn’t work, try the following:
Is nvidia driver properly installed? You can check by running nvidia-smi
Are openGL libraries visible? You can do so by
There are two ways of setting up openGL library, if the current installation doesn’t work, you can try to install with USE_GLAD set to FALSE in here
If you want to render in headless mode, make sure
$DISPLAYenvironment variable is unset, otherwise you might have error
Failed to EGL with glad, because EGL is sensitive to
Also, the EGL setup part is borrowed from Erwin Coumans egl_example. It would be informative to see if that repository can run on your machine.
