Compile
|
||
|
|
=======
|
||
|
|
|
||
|
|
## Native Compilation
|
||
|
|
|
||
|
|
As a prerequisite for compiling FRT, these packages should be enough
|
||
|
|
(using debian as an example):
|
||
|
|
|
||
|
|
$ sudo apt-get install build-essential scons pkg-config \
|
||
|
|
clang llvm lld libsdl2-dev libgles2-mesa-dev
|
||
|
|
|
||
|
|
Download and uncompress an official Godot source tarball from:
|
||
|
|
|
||
|
|
<https://github.com/godotengine/godot/releases>
|
||
|
|
|
||
|
|
or:
|
||
|
|
|
||
|
|
<https://downloads.tuxfamily.org/godotengine>
|
||
|
|
|
||
|
|
Here it is assumed that the top directory of the Godot source is ~/godot.
|
||
|
|
|
||
|
|
Go to the platform directory and clone this repository:
|
||
|
|
|
||
|
|
$ cd ~/godot
|
||
|
|
$ cd platform
|
||
|
|
$ git clone -b 2.0 https://github.com/efornara/frt
|
||
|
|
|
||
|
|
From the main directory, you now have a new platform available:
|
||
|
|
|
||
|
|
$ cd ~/godot
|
||
|
|
$ scons platform=frt tools=no target=release use_llvm=yes -j 4
|
||
|
|
|
||
|
|
_NOTE: If you only have access to a recent version of gcc (i.e. 6 or later),
|
||
|
|
you can only compile Godot 2 by using debug as a target._
|
||
|
|
|
||
|
|
## Cross compilation, crossbuild and release.sh
|
||
|
|
|
||
|
|
As an example, here are the steps needed to build some binaries on
|
||
|
|
a PC using docker. Even if you don't use docker, my crossbuild images
|
||
|
|
or the official script, these instructions, the Dockerfiles and the
|
||
|
|
script should have all the info that you need.
|
||
|
|
|
||
|
|
Create the docker images:
|
||
|
|
|
||
|
|
$ git clone https://github.com/efornara/crossbuild
|
||
|
|
$ cd crossbuild/docker
|
||
|
|
$ ./build.sh base
|
||
|
|
[...]
|
||
|
|
$ ./build.sh arm32v7
|
||
|
|
[...]
|
||
|
|
$ ./docker.sh arm32v7
|
||
|
|
root@.....:/# su - builder
|
||
|
|
builder@.....:$
|
||
|
|
|
||
|
|
You should be able to su to your user (builder in my case) and find your
|
||
|
|
home directory.
|
||
|
|
|
||
|
|
You might have everything you need in the container, but I usually
|
||
|
|
open another terminal and work outside the container, except for
|
||
|
|
compiling.
|
||
|
|
|
||
|
|
The release.sh script needs the current directory to look like this:
|
||
|
|
|
||
|
|
$ ls ~/somewhere
|
||
|
|
releases/ tag_216/ tag_342/
|
||
|
|
|
||
|
|
A directory where to copy the binaries (releases/) and every godot
|
||
|
|
version in its own directory named according to its "tag" version
|
||
|
|
and with frt already inside platform (see above).
|
||
|
|
|
||
|
|
From within the container, type:
|
||
|
|
|
||
|
|
$ cd ~/somewhere
|
||
|
|
$ ./tag_216/platform/frt/release.sh arm32v7 tag_*
|
||
|
|
|
||
|
|
If everything goes well, after a while you should have your binaries
|
||
|
|
ready in ~/somewhere/releases.
