FlatLaf Linux Native Library
|
|
============================
|
|
|
|
This sub-project contains the source code for the FlatLaf Linux native library.
|
|
|
|
The native library can be built only on Linux and requires a C++ compiler.
|
|
|
|
The native library is available for following CPU architectures: `x86_64` (or
|
|
`amd64`) and `arm64` (or `aarch64`).
|
|
|
|
To be able to build FlatLaf on any platform, and without C++ compiler, the
|
|
pre-built native libraries are checked into Git at
|
|
[flatlaf-core/src/main/resources/com/formdev/flatlaf/natives/](https://github.com/JFormDesigner/FlatLaf/tree/main/flatlaf-core/src/main/resources/com/formdev/flatlaf/natives).
|
|
|
|
The native libraries were built on a GitHub server with the help of GitHub
|
|
Actions. See:
|
|
[Native Libraries](https://github.com/JFormDesigner/FlatLaf/actions/workflows/natives.yml)
|
|
workflow. Then the produced Artifacts ZIP was downloaded and the native library
|
|
checked into Git.
|
|
|
|
|
|
## Development
|
|
|
|
To build the library on Linux, some packages needs to be installed:
|
|
|
|
- `build-essential` - GCC and development tools
|
|
- `libxt-dev` - X11 toolkit development headers
|
|
- `libgtk-3-dev` - GTK 3 toolkit development headers
|
|
- `g++-aarch64-linux-gnu` - GNU C++ compiler for the arm64 architecture (only on
|
|
x86_64 Linux for cross-compiling for arm64 architecture)
|
|
|
|
|
|
### Ubuntu
|
|
|
|
~~~
|
|
sudo apt-get update
|
|
sudo apt-get install build-essential libxt-dev libgtk-3-dev
|
|
~~~
|
|
|
|
#### Cross-compile for arm64 architecture on x86_64 Linux
|
|
|
|
Only needed on x86_64 Linux if you want cross-compile for arm64 architecture:
|
|
|
|
~~~
|
|
sudo apt-get install g++-aarch64-linux-gnu
|
|
~~~
|
|
|
|
Download `libgtk-3.so` for arm64 architecture:
|
|
|
|
~~~
|
|
cd flatlaf-natives/flatlaf-natives-linux/lib/aarch64
|
|
wget --no-verbose https://ports.ubuntu.com/pool/main/g/gtk%2b3.0/libgtk-3-0_3.24.18-1ubuntu1_arm64.deb
|
|
ar -x libgtk-3-0_3.24.18-1ubuntu1_arm64.deb data.tar.xz
|
|
tar -xvf data.tar.xz --wildcards --to-stdout "./usr/lib/aarch64-linux-gnu/libgtk-3.so.0.*" > libgtk-3.so
|
|
rm libgtk-3-0_3.24.18-1ubuntu1_arm64.deb data.tar.xz
|
|
~~~
|
|
|
|
|
|
### Fedora
|
|
|
|
~~~
|
|
sudo dnf group install c-development
|
|
sudo dnf install libXt-devel gtk3-devel
|
|
~~~
|
|
|
|
|
|
### CentOS
|
|
|
|
~~~
|
|
sudo yum install libXt-devel gtk3-devel
