failed to EGL with glad

[hiyyg]

Hello, I tried to run the egl renderer example examples/pybullet/examples/testrender_egl.py,
but I got this error:
failed to EGL with glad.
Do you know how to solve this?

Probably:

1. No EGL library (libEGL.so.1, libEGL.so), try ldconfig -p | grep EGL
2. No default display eglGetCurrentDisplay()/eglGetDisplay(EGL_DEFAULT_DISPLAY)
   (glad with EGL on Github workflows Dav1dde/glad#297)

I can use the EGL example provided by https://github.com/mmatl/pyrender. I think there is some other problem.

The same error failed to EGL with glad, though show_gui=False.
The output of the commands
cd calvin_env/egl_check bash build.sh # should have been built automatically, but try running this again python list_egl_options.py
is:
