# How to compile LWJGL2 for Apple Silicon
|
|
LWJGL2 does not provide official native ARM support, therefore Ocelot uses a specially modified version by **shadowfacts**
|
|
|
|
Article: https://shadowfacts.net/2022/lwjgl-arm64/
|
|
|
|
Repository: https://github.com/shadowfacts/lwjgl2-arm64
|
|
|
|
This procedure is completely optional, as the precompiled library is already checked into the repository at `lib/native/liblwjgl-arm64.dylib`
|
|
|
|
## Compilation
|
|
This assumes that you are running macOS on **Apple Silicon** *(cross-compiling LWJGL seems to be impossible)*
|
|
|
|
1. Acquire a JDK8 built for ARM - for example, [Zulu 8 JDK](https://www.azul.com/downloads/?version=java-8-lts&os=macos&architecture=arm-64-bit&package=jdk#zulu), and add it to your `JAVA_HOME`
|
|
2. Get [`maven`](https://maven.apache.org/) and [`ant`](https://ant.apache.org/) - you may install them via `brew`, but be careful, as they will try to install a JDK as a dependency
|
|
3. Clone the LWJGL repository:
|
|
```bash
|
|
% git clone https://github.com/shadowfacts/lwjgl-arm64.git
|
|
```
|
|
4. Run the following commands in the repo:
|
|
```bash
|
|
% ant generate-all
|
|
% ant jars
|
|
% ant compile-native
|
|
```
|
|
5. Copy the compiled library from `libs/macosx/liblwjgl.dylib` into the `ocelot-desktop` project as `lib/native/liblwjgl-arm64.dylib` |
