From PyPI (pip)

ModernGL is available on PyPI for Windows, OS X and Linux as pre-built wheels. No complication is needed unless you are setting up a development environment.

$ pip install moderngl

Verify that the package is working:

$ python -m moderngl
moderngl 5.6.0
--------------
vendor: NVIDIA Corporation
renderer: GeForce RTX 2080 SUPER/PCIe/SSE2
version: 3.3.0 NVIDIA 441.87
python: 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 19 2019, 00:42:30) [MSC v.1916 64 bit (AMD64)]
platform: win32
code: 330

Note

If you experience issues it’s probably related to context creation. More configuration might be needed to run moderngl in some cases. This is especially true on linux running without X. See the context section.

Development environment

Ideally you want to fork the repository first.

# .. or clone for your fork
git clone https://github.com/moderngl/moderngl.git
cd moderngl

Building on various platforms:

  • On Windows you need visual c++ build tools installed: https://visualstudio.microsoft.com/visual-cpp-build-tools/
  • On OS X you need X Code installed + command line tools (xcode-select --install)
  • Building on linux should pretty much work out of the box
  • To compile moderngl: python setup.py build_ext --inplace

Package and dev dependencies:

  • Install requirements.txt, tests/requirements.txt and docs/requirements.txt
  • Install the package in editable mode: pip install -e .

Using with Mesa 3D on Windows

If you have an old Graphics Card that raises errors when running moderngl, you can try using this method, to make Moderngl work.

There are essentially two ways, * Compling Mesa yourselves see https://docs.mesa3d.org/install.html. * Using msys2, which provids pre-compiled Mesa binaries.

Using MSYS2

32-bit python

If you have 32-bit python, then open C:\msys64\mingw32.exe and type the following

pacman -S mingw-w64-i686-mesa

It will install mesa and it’s dependencies. Then you can add C:\msys64\mingw32\bin to PATH before C:\Windows and moderngl should be working.

64-bit python

If you have 64-bit python, then open C:\msys64\mingw64.exe and type the following

pacman -S mingw-w64-x86_64-mesa

It will install mesa and it’s dependencies. Then you can add C:\msys64\mingw64\bin to PATH before C:\Windows and moderngl should be working.
