Introduction to the buildsystem¶
Godot uses SCons to build. We love it, we are not changing it for anything else. We are not even sure other build systems are up to the task of building Godot. We constantly get requests to move the build system to CMake, or Visual Studio, but this is not going to happen. There are many reasons why we have chosen SCons over other alternatives, for example:
Godot can be compiled for a dozen different platforms: all PC platforms, all mobile platforms, many consoles, and WebAssembly.
Developers often need to compile for several of the platforms at the same time, or even different targets of the same platform. They can't afford reconfiguring and rebuilding the project each time. SCons can do this with no sweat, without breaking the builds.
SCons will never break a build no matter how many changes, configurations, additions, removals etc. You have more chances to die struck by lightning than needing to clean and rebuild in SCons.
Godot build process is not simple. Several files are generated by code (binders), others are parsed (shaders), and others need to offer customization (plugins). This requires complex logic which is easier to write in an actual programming language (like Python) rather than using a mostly macro-based language only meant for building.
Godot build process makes heavy use of cross-compiling tools. Each platform has a specific detection process, and all these must be handled as specific cases with special code written for each.
So, please try to keep an open mind and get at least a little familiar with it if you are planning to build Godot yourself.
Please refer to the documentation for Compiling for Android, Compiling for iOS, Compiling for Linux, *BSD, Compiling for macOS, Compiling for Universal Windows Platform, Compiling for the Web, and Compiling for Windows.
Note that for Windows/Visual Studio, you need to use
x86_x64 Cross Tools
Command Prompt for VS 2017 or similar, depending on your install, instead of
the standard Windows command prompt to enter the commands below.
Godot's build system will begin by detecting the platforms it can build for. If not detected, the platform will simply not appear on the list of available platforms. The build requirements for each platform are described in the rest of this tutorial section.
SCons is invoked by just calling
scons. If no platform is specified,
SCons will detect the target platform automatically based on the host platform.
It will then start building for the target platform right away.
To list the available target platforms, use
To build for a platform (for example,
linuxbsd), run with the
p= to make it short) argument:
This will start the build process, which will take a while. By default, Godot's
SCons setup is configured to use all CPU threads but one (to keep the system
responsive during compilation). If you want to adjust how many CPU threads SCons
will use, use the
-j <threads> parameter to specify how many threads will be
used for the build.
Example for using 4 threads:
scons platform=linuxbsd -j4
The resulting binaries will be placed in the
generally with this naming convention:
For the previous build attempt, the result would look like this:
ls bin bin/godot.linuxbsd.editor.x86_64
This means that the binary is for Linux or *BSD (not both), is not optimized, has the whole editor compiled in, and is meant for 64 bits.
A Windows binary with the same configuration will look like this:
C:\godot> dir bin/ godot.windows.editor.64.exe
Copy that binary to any location you like, as it contains the Project Manager, editor and all means to execute the game. However, it lacks the data to export it to the different platforms. For that the export templates are needed (which can be either downloaded from
