Compiling for X11 (Linux, *BSD)

Requirements

For compiling under Linux or other Unix variants, the following is required:

  • GCC or Clang
  • Python 3 or 2.7+
  • SCons build system (3.0 or later for Python 3)
  • pkg-config (used to detect the dependencies below)
  • X11, Xcursor, Xinerama, Xi and XRandR development libraries
  • MesaGL development libraries
  • ALSA development libraries
  • PulseAudio development libraries
  • Optional - libudev (build with udev=yes)
  • Optional - yasm (for WebM SIMD optimizations)

Compiling

Start a terminal, go to the root dir of the engine source code and type:

user@host:~/godot$ scons -j8 platform=x11

A good rule of thumb for the -j (jobs) flag, is to have at least as many threads compiling Godot as you have cores in your CPU, if not one or two more. Feel free to add the -j option to any SCons command you see below.

If all goes well, the resulting binary executable will be placed in the “bin” subdirectory. This executable file contains the whole engine and runs without any dependencies. Executing it will bring up the project manager.

Note

If you wish to compile using Clang rather than GCC, use this command:

user@host:~/godot$ scons platform=x11 use_llvm=yes

Using Clang appears to be a requirement for OpenBSD, otherwise fonts would not build.

Note

If you are compiling Godot for production use, then you can make the final executable smaller and faster by adding the SCons option target=release_debug.

Building export templates

Warning

Linux binaries usually won’t run on distributions that are older than the distribution they were built on. If you wish to distribute binaries that work on most distributions, you should build them on an old distribution such as Ubuntu 16.04. You can use a virtual machine or a container to set up a suitable build environment.

To build X11 (Linux, *BSD) export templates, run the build system with the following parameters:

  • (32 bits)
user@host:~/godot$ scons platform=x11 tools=no target=release bits=32
user@host:~/godot$ scons platform=x11 tools=no target=release_debug bits=32
  • (64 bits)
user@host:~/godot$ scons platform=x11 tools=no target=release bits=64
user@host:~/godot$ scons platform=x11 tools=no target=release_debug bits=64

Note that cross-compiling for the opposite bits (64/32) as your host platform is not always straight-forward and might need a chroot environment.

To create standard export templates, the resulting files must be copied to:

$HOME/.local/share/godot/templates/[gd-version]/

and named like this (even for *BSD which is seen as “Linux X11” by Godot):

linux_x11_32_debug
linux_x11_32_release
linux_x11_64_debug
linux_x11_64_release

However, if you are writing your custom modules or custom C++ code, you might instead want to configure your binaries as custom export templates here:

../../_images/lintemplates.png

You don’t even need to copy them, you can just reference the resulting files in the bin/ directory of your Godot source folder, so the next time you build, you automatically have the custom templates referenced.
