You need to install gcc with "sudo apt install gcc"

When hhaving that activated you have an app folder called Linux in that there is a terminal. That will you need. In the terminal you need to download the source code. Run in the terminal "sudo apt install git libeigen3-dev libsfml-dev make cmake" to install the dependencies. Now run "git clone https://github.com/HackerPoet/MarbleMarcher" to clone the git repo. Then "cd MarbleMarcher" to open that folder and then execute "mkdir build && cd build" to create a new folder and open it "cmake .." to setup the build system "cd .." to get back to the root folder "cmake --build build" to build it

How would it be with Linux? Chrome Os has support for running Linux executables. Also you could try to run it with wine or mono.

Are you talking about a Chrome Book? When yes you can just enable linux mode and recompile it.
