Here are some steps you can make Minecraft Bedrock supported on Linux

I want you to build a version of Minecraft: Bedrock Edition for Linux:

1. Get a Linux machine, if you have an existing one, you don't need to.

2. Make a project folder in the Linux machine (e.g. ~/minecraft-bedrock-for-linux). Use the mkdir command to create a directory. Usage: mkdir -p foldername

3. Make the source code for the project

4. Since Minecraft Bedrock is built in C++, use a tool called GCC to compile the source code. (If you don't know what is GCC or how to use it, GCC is a C/C++ compiler for Linux. If you want to see how to use GCC, then type: gcc --help.)

5. Upload the Minecraft Bedrock executable to your resources.download.minecraft.net server.

6. Update the Minecraft Launcher so that the Play button for the Minecraft Bedrock tab is not greyed out.
