Building From Source

:::{error} The project is undergoing significant changes in the upgrade to Godot 4. Therefore, the documentation about building from source is out of date. This documentation will be updated before the next release. :::

Building GodotXterm from source consists of four steps:

  1. Clone git submodules.
  2. Compile libuv using CMake.
  3. Compile godot-cpp using scons.
  4. Compile libtsm and libgodotxterm using scons.

:::{hint} This plugin follows the same format as the {{ 'GDNative C++ Example'.format(godot_docs) }}. So if you can compile that example then you are 90% of the way there. The main difference is using CMake to compile libuv. :::

Dependencies

  • Git (to clone git submodules)
  • SCons (a software construction tool)
  • A C/C++ compiler (i.e. gcc, llvm, MSVC)
  • CMake (to compile libuv)

The Easy Way

Run the build script in addons/godot-xterm/native:

cd addons/godot_xterm/native
./build.sh

:::{tip} On Windows, you can use git-bash to run this script. Provided the dependencies above are installed then it should "just work™". :::

Binaries for your platform will be installed in addons/godot_xterm/native/bin.

The {{ 'build.sh'.format(repo) }} script accepts args --target which can be set to debug (default) or release and --disable-pty to compile only the dependencies of {{Terminal}} node and not {{PTY}} node (even on platforms that support it).

The Hard Way

If you are having trouble compiling, study the {{ 'build.sh'.format(repo) }} script and the GitHub actions workflow in {{ main.yml'.format(repo) }} to see what commands are being run and how dependencies are installed. You can also dig into the {{ 'SConstruct'.format(repo) }} file, and don't forget to refer back to the {{ 'GDNative C++ Example'.format(godot_docs) }}.

Also feel free to open a new discussion in the discussions section of the project repo.

Cross Compiling

Although the SConstruct file contains some logic for cross-compiling, it has never been tested. If you want compile for other platforms consider forking this repo and then pushing your changes to GitHub. The workflow defined in {{ 'main.yml'.format(repo) }} will run and build the library for all supported platforms (Linux, macOS, Windows, and Web).

Additionally, If you have docker and docker-compose installed, the {{ 'build.sh'.format(repo) }} script will also try to build the Web binary inside a docker container and copy them to addons/godot_xterm/native/bin.
