Minecraft 1.20.2 on FreeBSD: Getting Started

This repository uses LWJG from #431.

If you are affected by #8, use this version of the repo instead of the normal one!

Thanks to their work!

with the build versions of er2off used here

You will now be able to run Minecraft 1.20.2 on FreeBSD.

And Minecraft will be able to recognize multiple cpu cores!(for me, only 1.20.2 now, you maybe want Check the link above)

Setting up Prism Launcher

We will mostly be following the OpenBSD build instructions at https://prismlauncher.org/wiki/development/build-instructions/#openbsd.

0. Install Dependencies: sudo pkg install qt5 qt6 cmake kf5-extra-cmake-modules openjdk8 openjdk17 lwjgl glfw git
1. Clone the repo: git clone --recursive https://github.com/PrismLauncher/PrismLauncher.git and cd PrismLauncher
2. Configure environment: cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/usr/local" -DCMAKE_PREFIX_PATH=/usr/local/lib/qt5/cmake -DENABLE_LTO=ON
3. Actually build Prism Launcher: cd build and sudo make -j$(nproc) install

Building LWJGL3 and configuring script

For FreeBSD 13.2+ or other version:

Before we get started, you might want to check this.

---

1. Download lwjgl3.tar.gz and extract it somewhere.

2. Go to the folder you extracted, make install clean

3. If the build succeeds, you should be able to find the built files in the following path:

   /usr/local/lib/lwjgl3

   /usr/local/share/java/classes/lwjgl3

   This should be correct for FreeBSD 13.2, But if not, open minecraft-runtime in a text editor, modify it:

   LWJGL_JLP_OVRD

   LWJGL_OVRD

   LWJGL_OGL_OVRD

   LWJGL_OAL_OVRD

   LWJGL_GLFW_OVRD

   LWJGL_STB_OVRD

   LWJGL_JEM_OVRD

---

Configuring Prism

1. Go to Settings (either Global or Instance), then go in the Java section.
2. Set Java Runtime/Tick and set Java Installation to the location of the minecraft-runtime script from the make install step above this one.
3. Click Test, if you did everything correctly, it should say that the Test succeeded.

IMPORTANT: FOR PEOPLE RUNNING SNAPSHOTS OF 1.13 AND LOWER:

You need to add -Dorg.lwjgl.librarypath=/usr/local/lib/lwjgl as a additional flag (Thanks to @er2off on Discord for this info.)
