Due to licensing problems that we are trying to resolve, we cannot release a binary for Mac OS X at this time. However, the compiler was tested and developed on a Mac, and you may easily compile it from the source code. Instructions for doing so are as follows:

• Download and install the Glasgow Haskell Compiler (GHC 6.6). The Flapjax compiler is written in Haskell with some GHC-specific extensions.
• Download the extract the Flapjax source.
• From the Terminal, navigate to the compiler directory of the Flapjax source.
• Type make to build the fjc binary.
• Make is available on most Mac OS X systems. If you do not have Make, you can type ghc --make -o fjc Fjc.hs to build the compiler.
