The Open Edition of the F# Compiler, Core Library & Tools
The main purpose of this repository is to package the open editions of the F# compiler, core library and core tools for use across multiple platforms.
Contributing to the F# Compiler, Core Library and Tools
Most contributions to the F# compiler/library/tools go first via the
repository at https://github.com/Microsoft/visualfsharp. This ensures that the main packaging of F# on Windows (the Visual F# Tools) also includes any contributions that are made, and ensures that the versions do not diverge.
If you are using Windows, you should fork that repo and contribute directly there. Your contributions will then be merged into this repo.
If you are using Linux or OSX, you can prepare your contributions by forking this repository (the code is essentially the same). This will give you access to the cross-platform testing available from this repo. At the moment the process is:
- Fork this repo.
- Build and test using the subset of tests available in this repo. If you like, submit a PR to this repo in order to trigger an automatic Travis run, or set up a Travis hook in your fork.
- Seek initial review by posting an issue in this repository or https://github.com/Microsoft/visualfsharp. Make it clear you are working on Linux or OSX.
- Cherry-pick your changes into a pull request for https://github.com/Microsoft/visualfsharp and submit for final testing and clearance.
- The change will then be merged into this repo at a later point.
If you don't have access to Windows in order to run final tests at step 4. If you need help, email email@example.com and ask to make a final test run on Windows.
Contributions specifically related to the packaging of the Open Edition should be made here.
master branch is for F# 3.1. The
fsahrp4 branch is for F# 4.0.
To bootstrap the compiler, binaries built from an earlier version of this project are used.
This codebase uses the Apache 2.0 license.
Current Build Status
NuGet Feed of FSharp.Core and FSharp.Compiler.Tools packages
This repo is curently used to make two NuGet pacakges - FSharp.Core and FSharp.Compiler.Tools.
Stable builds are available in the NuGet Gallery: http://www.nuget.org/packages/FSharp.Core and http://www.nuget.org/packages/FSharp.Compiler.Tools.
The FSharp.Core NuGet package includes all of the FSharp.Core redistributables from Visual F#. In addition, they include assemblies for MonoAndroid and MonoTouch built from this repository.
The FSharp.Compiler.Tools package includes the F# compiler
fsc.exe, F# Interactive
fsi.exe, build support,
a copy of FSharp.Core used to run the tools, and related DLLs.
A feed of nuget packages from builds is available from AppVeyor using the NuGet feed: https://ci.appveyor.com/nuget/fsgit-fsharp
If using Paket, add the source at the top of
source https://www.nuget.org/api/v2 source https://ci.appveyor.com/nuget/fsgit-fsharp
Add the dependency on
FSharp.Core and run
paket update. See the AppVeyor build history for a list of available versions. Here are some options for specifying the dependency:
nuget FSharp.Core nuget FSharp.Core prerelease nuget FSharp.Core 18.104.22.168 nuget FSharp.Core 22.214.171.124-b208
If using NuGet Package Manager, add the source to the list of available package sources.
Requires mono 3.0 or higher.
OS X requires automake 2.69. To install from homebrew:
brew install automake
How to Build
Linux and other Unix systems:
./autogen.sh --prefix=/usr make sudo make install
By default that makes optimized binaries. To make debug, use
Use a prefix to your version of Mono:
./autogen.sh --prefix=/Library/Frameworks/Mono.framework/Versions/Current/ make sudo make install
By default that makes optimized binaries. To make debug, use
Windows, using msbuild
If you have only VS2012 or VS2013 installed, and not VS2010, you'll need to install the F# 2.0 Runtime (http://www.microsoft.com/en-us/download/details.aspx?id=13450).
This build the proto compiler, then the library, then the final compiler.
You can also build these independently using:
msbuild src\fsharp-proto-build.proj ngen install ..\lib\proto\fsc-proto.exe msbuild src\fsharp-library-build.proj /p:Configuration=Release msbuild src\fsharp-compiler-build.proj /p:Configuration=Release
You can also build FSharp.Core.dll for other profiles:
msbuild src\fsharp-library-build.proj /p:TargetFramework=net20 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=portable47 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=portable7 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=portable78 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=portable259 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=sl5 /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=monodroid /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=monotouch /p:Configuration=Release msbuild src\fsharp-library-build.proj /p:TargetFramework=net40-xna40-xbox360 /p:Configuration=Release
You can also build the FSharp.Core and FSharp.Compiler.Silverlight.dll for Silverlight 5.0:
msbuild src\fsharp-library-build.proj /p:TargetFramework=sl5-compiler /p:Configuration=Release
/p:Configuration=Debug for debug binaries.
/p:FSharpCoreBackVersion=3.0 to build a back version of FSharp.Core.dll with a
version number suitable for use when building libaries that have usable with both F# 3.0 and F# 3.1 libraries.
msbuild src\fsharp-library-build.proj /p:TargetFramework=net20 /p:Configuration=Release /p:FSharpCoreBackVersion=3.0 msbuild src\fsharp-library-build.proj /p:TargetFramework=net40 /p:Configuration=Release /p:FSharpCoreBackVersion=3.0 msbuild src\fsharp-library-build.proj /p:TargetFramework=portable47 /p:Configuration=Release /p:FSharpCoreBackVersion=3.0
Windows, using xbuild (e.g. if no .NET is installed and only Mono 3.0 is installed):
xbuild src\fsharp-proto-build.proj xbuild src\fsharp-library-build.proj xbuild src\fsharp-compiler-build.proj
Building using xbuild does not yet lay down a Mono-ready distribution (see src/fsharp/targets.make), so should only be used for private development rather than preparing distributions.
Build Note: Strong Names
The FSharp.Core.dll produced is only delay-signed (Mono does not require strong names). If a strong-name signed FSharp.Core.dll is needed then use the one in
How to Install
Built main compiler binaries go to lib/release/4.0
Additionally, versions of FSharp.Core for .NET 2.0, MonoAndroid, MonoTouch (Mono profile 2.1) go to lib/release/2.0 lib/release/2.1 lib/release/2.1monotouch
make install sends the binaries to the
prefix location, e.g.
/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/2.0/FSharp.Core.dll /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/2.1/FSharp.Core.dll /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.0/fsc.exe /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.0/FSharp.Compiler.dll ... /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/fsc.exe /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/FSharp.Compiler.dll ... /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/gac/.../FSharp.Compiler.dll /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/gac/.../FSharp.Compiler.dll ...
plus some files for xbuild support
/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/Microsoft\ F#/v4.0/* /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/Microsoft\ SDKs/F#/3.0/Framework/*
(these names are the canonical names for Microsoft.FSharp.Targets used by project files coming from Visual Studio)
/usr/bin/fsharpc (F# compiler) /usr/bin/fsharpi (F# Interactive)

Continuous Integration Build
A continuous integration build is set up with Travis. See above.
Editing the Compiler with Visual Studio, Xamarin Studio or MonoDevelop
all-vs2013.sln, and edit in modes Debug or Release. The compiler takes a good while to compile and that
can be a bit invasive to the work flow, so it's normally better to do the actual compilation from
the command line, see above.
Historically it is difficult to edit the compiler with Xamarin Studio or MonoDevelop because of bugs in loading the hand-edited project files and targets used in the F# compiler build. These are generally in the process of being fixed, your mileage will vary.
How to Test and Validate
Linux and OSX
Only a subset of the tests are currently enabled.
After building and installing, run
cd tests/fsharp/core ./run-all.sh
See the TESTGUIDE.md for instructions for how to test on Windows. Use that repository to develop and test on Windows.
F# compiler sources as initially dropped are available from fsharppowerpack.codeplex.com.
On 4 April 2014, Microsoft Open Tech published the F# compiler sources at http://visualfsharp.codeplex.com and began accepting contributions to the F# compiler/library and tools. This repository is a modified version of that.
This repository uses bootstrapping libraries, tools and F# compiler. The
lib/bootstrap/X.0 directories contain mono-built libraries, compiler and tools that can be used to bootstrap a build. You can also supply your own via the
vagrant up vagrant ssh cd /vagrant sudo apt-get install dos2unix autoconf ./autogen.sh --prefix=/usr make sudo make install
