Linux

Ensure SDL2 is installed. Most package managers ought to have this available. For example, on Ubuntu, it should be sufficient to run:

sudo apt install libsdl2-dev
sudo apt install libsdl2-net-dev

And then build Supermodel:

make -f Makefiles/Makefile.UNIX

For network support:

make -f Makefiles/Makefile.UNIX NET_BOARD=1

macOS

Ensure Apple's Xcode Command Line Tools are installed:

From a terminal:

xcode-select --install

Ensure SDL2 is installed. Download the latest *.dmg files from both of the links below, and install per the READMEs in the .dmgs (i.e. in "/Library/Frameworks")

• SDL2: https://github.com/libsdl-org/SDL/releases

• SDL_net: https://github.com/libsdl-org/SDL_net/releases

And then build Supermodel:

make -f Makefiles/Makefile.OSX

For network support:

make -f Makefiles/Makefile.OSX NET_BOARD=1

Note: running on macOS

If you try and run a macOS binary that was downloaded from the internet and/or built on a different machine, you need to grant macOS permission to execute the binary (just 1-time):

• Open the folder containing the binary in Finder, and right (or ctrl) click on it:

• Click "Open" when the following dialogue box appears : "macOS cannot verify the developer of “supermodel-git-xxxx”. Are you sure you want to open it?"

• Close the terminal window that opens (after clicking open)
