If you don't havebrew installed, see#177

This solution is relevant if you get an long error message when runningcargo build ending in:

ld: library not found for -lSDL2

Lacking permission to link SDL2

On some computers, the brew command fails to create the symlinks to the libraries it installs. This means the Rust compiler can not find them. To get permission to do this, use thechown command as following:

brew install sdl2sudo chown root:wheel /usr/local/bin/brewbrew unlink sdl2 && brew link sdl2

Missing path in LIBRARY_PATH environment variable

The Homebrew package manager symlinks library to the directory/usr/local/lib. To use these libraries with Rust, you need to add it to theLIBRARY_PATH environment variable. The commandecho $LIBRARY_PATH will tell you if/usr/local/lib is added. If it is missing, add the following to the~/.bash_profile configuration file:

export LIBRARY_PATH="$LIBRARY_PATH:/usr/local/lib"

This will add the directory to the environment variable each time you start up a new Terminal window.

export LIBRARY_PATH="$LIBRARY_PATH:/opt/homebrew/lib
