What can I do to solve "failed to EGL with glad"?

[pranavgundewar]

I am facing same error

[AddASecond]

If you want to render in headless mode, make sure $DISPLAY environment variable is unset, otherwise you might have error Failed to EGL with glad, because EGL is sensitive to $DISPLAY environment variable. unset $DISPLAY or unset DISPLAY

Although I see the 'libEGL' libraries, I am still facing the same error even when I run 'list_egl_options.py' for verification. I have seen in other places that the 'libEGL_nvidia.so*' libraries are also needed. Is that the case?

I also have the same error

[CostaliyA]

I also have the same error and unset DISPLAY can help me. Thx :D

I also have the same error and unset DISPLAY can help me. Thx :D

I tried,but it is unuseful. also thank you

@ZZC-CN Recently, to convenient for user to use my repo, I built a docker for my work Corki, I faced the same problem as you, and I finally sovled it, you can see my Dockerfile guidance Corki and my solvement for this problem, I think there are two main reasons:

1. Some packages are missing, check the dockerfile here:Dockerfile
2. Missing EGL ICD configuration file, I don't know why this file still missing although I run the docker with argument-e NVIDIA_DRIVER_CAPABILITIES=all, so I add it with scirpts see:prepare.sh

After finishing these process, I get the right result, that calvin use gpu to render:

I'm not sure if this will solve your problem, but I welcome people who encounter this problem to try it. If it works for everyone, I'll consider submitting a pull request for docker installation guidance to the calvin repo.

@sb93 I also have the same error. Did you successfully download the 'libEGL_nvidia.so*' libraries? I used this command to check the download status of EGL and found that Nvidia's EGL is missing.

How did you download libEGL_nvidia.so.0?
