This is the F# compiler, core library and core tools (open source edition). It uses the Apache 2.0 license.
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
On Linux and other Unix systems:
./autogen.sh make sudo make install
On MacOS (OSX)
Use a prefix to your version of Mono:
./autogen.sh --prefix=/Library/Frameworks/Mono.framework/Versions/Current/ make sudo make install
On Windows, using msbuild (e.g.. if .NET is installed)
cd src msbuild fsharp-proto-build.proj ngen install ..\lib\proto\4.0\fsc-proto.exe msbuild fsharp-library-build.proj msbuild fsharp-compiler-build.proj
You can also build the FSharp.Core for .NET 2.0, Mono 2.1, Silverlight 5.0, Portable Profile47 (net4+sl4+wp71+win8) and XNA 4.0 for Xbox 360 profiles:
msbuild fsharp-library-build.proj /p:TargetFramework=net20 msbuild fsharp-library-build.proj /p:TargetFramework=mono21 msbuild fsharp-library-build.proj /p:TargetFramework=portable-net4+sl4+wp71+win8 msbuild fsharp-library-build.proj /p:TargetFramework=sl5 msbuild fsharp-library-build.proj /p:TargetFramework=net40-xna40-xbox360
You can also build the FSharp.Core and FSharp.Compiler.Silverlight.dll for Silverlight 5.0:
msbuild fsharp-library-build.proj /p:TargetFramework=sl5-compiler msbuild fsharp-compiler-build.proj /p:TargetFramework=sl5-compiler
On Windows, using xbuild (e.g. if no .NET is installed and only Mono 3.0 is installed):
cd src xbuild fsharp-proto-build.proj xbuild fsharp-library-build.proj xbuild 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.
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
What you get
Once built the main compiler binaries go in lib/release/4.0
There are versions of FSharp.Core for .NET 2.0 and MonoAndroid (Mono profile 2.1) in lib/release/2.0 lib/release/2.1
On 'make install' the binaries etc. go in the prefix, 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
We have a CI build set up with the JetBrains/Teamcity server as part of the F# community projects there:
@forki controls access. Right now this builds both a Mono 'make' install and a Windows 'cd src; msbuild fsharp-build.proj' build. No binaries are saved from the build, it is just for sanity checking.
Editing the Compiler with Visual Studio or MonoDevelop
all-vs2012.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.
The F# support in MonoDevelop uses an in-process background compiler. On the Mac this causes pausing garbage collections to kick in which makes editing the compiler in MonoDevelop awkward.
Building F# Core Unit Tests for .NET 4.x (optional)
This uses the proto compiler to build the unit tests that check some parts of
FSharp.Compiler.dll. There is also another set of tests under
msbuild fsharp-library-unittests-build.proj /p:TargetFramework=net40
Note: You must have NUnit installed to build the unit tests.
Validation and Use
Here are some simple tests to validate what you have built by checking
fsi.exe (F# Interactive) starts up:
lib\debug\4.0\fsi.exe 1 + 1;; \#q;; lib\debug\4.0\fsi.exe /help lib\debug\4.0\fsc.exe /help echo printfn "hello world" > hello.fs lib\debug\4.0\fsc.exe hello.fs hello.exe
Running Compiler tests (on Windows)
There are language tests under
tests\fsharp\core. The test apparatus is primitive and unfortunately uses batch files. You can run these on Windows using:
cd ..\tests\fsharp\core ..\..\build-and-run-all-installed-ilx-configs.bat results.log
The results file will contain one entry for each test directory, plus any reported errors.
tests\fsharp\core tests\fsharp\core\queriesCustomQueryOps tests\fsharp\core\queriesLeafExpressionConvert tests\fsharp\core\queriesNullableOperators tests\fsharp\core\queriesOverIEnumerable ...
Some tests for LINQ queries require SQL Server be installed. A failing test will look like this:
ERRORLEVEL=1: in tests\fsharp\core\csfromfs\build.bat
You can then go to the relevant directory and run
F# compiler sources dropped by Microsoft are available from fsharppowerpack.codeplex.com.
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
