Kompilieren für X11 (Linux, *BSD)

Voraussetzungen

Zum Kompilieren unter Linux oder anderen Unix-Varianten ist Folgendes erforderlich:

  • GCC 7+ oder Clang 6+.
  • Python 3.5+.
  • SCons 3.0+ build system. If your distribution uses Python 2 by default, or you are using a version of SCons prior to 3.1.2, you will need to change the version of Python that SCons uses by changing the shebang (the first line) of the SCons script file to #! /usr/bin/python3. Use the command which scons to find the location of the SCons script file.
  • pkg-config (used to detect the dependencies below).
  • X11, Xcursor, Xinerama, Xi and XRandR development libraries.
  • MesaGL Entwicklungsbibliotheken.
  • ALSA-Entwicklungsbibliotheken.
  • PulseAudio Entwicklungsbibliotheken.
  • Optional - libudev (build with udev=yes).
  • Optional - yasm (for WebM SIMD optimizations).

Kompilieren

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

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.

Bemerkung

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

scons platform=x11 use_llvm=yes

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

Bemerkung

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.

If you are compiling Godot with GCC, you can make the binary even smaller and faster by adding the SCons option use_lto=yes. As link-time optimization is a memory-intensive process, this will require about 3 GB of available RAM while compiling.

Bemerkung

If you want to use separate editor settings for your own Godot builds and official releases, you can enable Self-contained mode by creating a file called ._sc_ or _sc_ in the bin/ folder.

Compiling a headless/server build

To compile a headless build which provides editor functionality to export projects in an automated manner, use:

scons -j8 platform=server tools=yes target=release_debug

To compile a server build which is optimized to run dedicated game servers, use:

scons -j8 platform=server tools=no target=release

Building export templates

Warnung

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.

Führen Sie das Build-System mit den folgenden Parametern aus, um X11-Exportvorlagen (Linux,* BSD) zu erstellen:

  • (32 Bit)
scons platform=x11 tools=no target=release bits=32
scons platform=x11 tools=no target=release_debug bits=32
  • (64 Bit)
scons platform=x11 tools=no target=release bits=64
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.

Using Clang and LLD for faster development

You can also use Clang and LLD to build Godot. This has two upsides compared to the default GCC + GNU ld setup:

  • LLD links Godot significantly faster compared to GNU ld or gold. This leads to faster iteration times.
  • Clang tends to give more useful error messages compared to GCC.

To do so, install Clang and the lld package from your distribution's package manager then use the following SCons command:

scons platform=x11 use_llvm=yes use_lld=yes

It's still recommended to use GCC for production builds as they can be compiled using link-time optimization, making the resulting binaries smaller and faster.
