# ***freebsd-cross*** Docker image
2+
3+
***This Docker container is taken from [docker-freebsd-cross](https://github.com/chirontt/docker-freebsd-cross), with the removal of `meson` support.***
4+
5+
An Alpine-based Docker image for cross-compiling to any version of FreeBSD (amd64/arm64) using `clang`.
6+
7+
- Supports building images for `aarch64` & `x86_64` platforms
8+
- C/C++ cross-compilers are available via the `CLANG` and `CPPLANG` env variables
9+
- Allows FreeBSD's `pkg` dependency installation
10+
- Configures `pkgconf` (`pkg-config`)
11+
- GTK3 & GTK4 libraries for FreeBSD are installed in the image
12+
- OpenJDK 21 for FreeBSD is also installed in the image, and is available via the `FREEBSD_JAVA_HOME` env variable.
13+
14+
# Usage
15+
16+
## FreeBSD cross builds for default `x86_64` architecture
17+
18+
### Build Docker image for `x86_64` on Linux/x86_64
19+
20+
First, build the image for default `x86_64` architecture, on a Linux/x86_64 box:
21+
22+
```
23+
> docker build -t "freebsd-cross-x86_64" .
24+
```
25+
26+
### FreeBSD/x86_64 cross build for Eclipse SWT natives
27+
28+
Then, at the root of [eclipse.platform.swt](https://github.com/eclipse-platform/eclipse.platform.swt) 's working directory,
29+
execute the following commands:
30+
31+
```
32+
> cd bundles/org.eclipse.swt
33+
> java -Dws=gtk -Darch=x86_64 build-scripts/CollectSources.java -nativeSources \
34+
../../binaries/org.eclipse.swt.gtk.freebsd.x86_64/target/natives-build-temp
35+
> cd ../../binaries/org.eclipse.swt.gtk.freebsd.x86_64
36+
> docker run --rm --volume $(pwd):/workdir -it "freebsd-cross-x86_64" /bin/sh -c \
37+
'cd target/natives-build-temp && \
38+
export OS=FreeBSD MODEL=x86_64 SWT_JAVA_HOME=$FREEBSD_JAVA_HOME OUTPUT_DIR=../.. CC=$CLANG && \
39+
./build.sh install'
40+
```
41+
42+

45+
execute the following command:
46+
47+
```
48+
> docker run --rm --volume $(pwd)/features/org.eclipse.equinox.executable.feature/library:/workdir \
49+
--volume $(pwd)/../equinox.binaries:/output -it "freebsd-cross-x86_64" /bin/sh -c \
50+
'cd gtk && \
51+
