This is the F# compiler, core library and core tools (open source edition). It uses the Apache 2.0 license.

The master branch is for the latest version of F# (currently F# 3.0).

To bootstrap the compiler, binaries built from an earlier version of this project are used.


Requires mono 2.9 or higher. Prefer Mono 3.0.

On OSX, requires automake 2.69. To install from homebrew:

brew install automake


To build and install on non-MacOS systems:

sudo make install

On MacOS (OSX), use a prefix to your version of Mono:

./ --prefix=/Library/Frameworks/Mono.framework/Versions/Current/
sudo make install

To build the FSharp.Core.dll for Mono for Android, use:

make do-2-1

F# original powerpack sources are available from
