glfwInit fails without DISPLAY

[kgreenek]

I'm trying to use GLFW together with EGL in an environment where there is no X11 server (an arm nvidia xavier).

I found various forum posts and documentation suggesting that egl is supported by setting the GLFW_EGL_CONTEXT_API window hint. However, glfw is failing in the call to glfwInit(). I see the following error in the error handling callback.

GLFW ERROR (65544): X11: The DISPLAY environment variable is missing

Is it currently supported to run glfw in a headless mode (i.e. without x11)?

Any help appreciated!

After more searching, I realized this feature isn't implemented yet.
See: #1592

There appear to be a couple of abandoned PRs that are open to implement this, but they have not been merged.
e.g. #1608
