Running moderngl (and glcontext) python library

Hello! I'm trying to get moderngl python library working on termux.

First of all, I encountered this issue during installation

pip install moderngl

pip install moderngl

In file included from glcontext/x11.cpp:5:
      /data/data/com.termux/files/usr/include/X11/Xlib.h:44:10: fatal error: 'X11/X.h' file not found
         44 | #include <X11/X.h>
            |          ^~~~~~~~~
      1 error generated.
      error: command '/data/data/com.termux/files/usr/bin/aarch64-linux-android-clang' failed with exit code 1
      [end of output]

      error: command '/data/data/com.termux/files/usr/bin/aarch64-linux-android-clang' failed with exit code 1
      [end of output]

And fixed it with

apt install xorgproto

apt install xorgproto

, after which it installed correctly

Then I got an issue when running

moderngl.create_context(standalone=True)

moderngl.create_context(standalone=True)

which complained about lack of

libGL.so

libGL.so

, which I also fixed with

apt install mesa

apt install mesa

But now I get the following error, that I cannot solve

opengl_context = moderngl.create_context(standalone=True)
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/data/data/com.termux/files/usr/lib/python3.11/site-packages/moderngl/__init__.py", line 1936, in create_context
    ctx.mglo, ctx.version_code = mgl.create_context(glversion=require, mode=mode, **settings)
                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/data/data/com.termux/files/usr/lib/python3.11/site-packages/glcontext/__init__.py", line 90, in create
    return x11.create_context(**kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Exception: (standalone) XOpenDisplay: cannot open display

opengl_context = moderngl.create_context(standalone=True)
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/data/data/com.termux/files/usr/lib/python3.11/site-packages/moderngl/__init__.py", line 1936, in create_context

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Exception: (standalone) XOpenDisplay: cannot open display

To clarify, the only thing I need moderngl library for is to attempt to compile GLSL shaders and check them for errors, via Context.program() and Context.compute_shader()

Solution

Ahh nvm, I'm an idiot. I had a typo

env DISPLAY:=1

env DISPLAY:=1

instead of

env DISPLAY=:1

env DISPLAY=:1

So the solution to installing and running moderngl (and glcontext) python library in termux is:
Install necessary packages

pgk install mesa xorgproto libx11 x11-repo && pkg install termux-x11-nightly

pgk install mesa xorgproto libx11 x11-repo && pkg install termux-x11-nightly

Install python library

pip install moderngl

pip install moderngl

Install companion app APK from https://github.com/termux/termux-x11

Launch X11 server

termux-x11 :1 &

termux-x11 :1 &

Launch python script with a

DISPLAY=:1

DISPLAY=:1

prefix

DISPLAY=:1 python script.py

DISPLAY=:1 python script.py
