PRE-INSTALLATION

Before you install matrix-commander with pip install matrix-commander you must have libolm installed. pip installation will fail otherwise!

For e2ee support, python-olm is needed which requires the libolm C library (version 3.x).

On Debian, Ubuntu and Debian or Ubuntu derivate distributions do sudo apt install libolm-dev to install the libolm package.
On Fedora or Fedora derivate distributions do sudo dnf install libolm-devel to install the libolm package.
On MacOS one can use brew to install package libolm.

Make sure that version 3 is installed. Version 2 will not work.

For macOS Monterey 12.4 (21F79) (Apple M1 Pro) and similar please follow the these steps:

Install libolm, dbus and libmagic using Homebrew
Install matrix-commander using this command:
- pip3 install --global-option=build_ext --global-option="-I/opt/homebrew/include/" --global-option="-L/opt/homebrew/lib/" matrix-commander
