# Building Math.NET Numerics

If you do not want to use the official binaries, or if you like to modify, debug or contribute, you can compile locally either using Visual Studio or manually with the build scripts.

## VisualStudio or Xamarin Studio

We clearly separate dependency management from the IDE, you should therefore run restore.cmd or restore.sh once after every git checkout in order to restore the dependencies exactly as defined. Otherwise Visual Studio and other IDEs may fail to compile or provide correct IntelliSense.

Tests can be run with the usual integrated NUnit test runners or ReSharper.

## MSBuild or XBuild

Instead of a compatible IDE you can also build the solutions directly with msbuild, or on Mono with xbuild. You may need to run restore.cmd or restore.sh before, once after every git checkout in order to restore the dependencies.

 1: 2: 3: 4: 5:  restore.cmd (or restore.sh) # restore dependencies (once) msbuild MathNet.Numerics.sln # only build for .Net 4 (main solution) msbuild MathNet.Numerics.Net35Only.sln # only build for .Net 3.5 msbuild MathNet.Numerics.All.sln # full build with .Net 4, 3.5 and PCL profiles xbuild MathNet.Numerics.sln # build with Mono, e.g. on Linux or Mac 

## FAKE

The fully automated build including unit tests, documentation and api reference, NuGet and Zip packages is using FAKE.

FAKE itself is not included in the repository but it will download and bootstrap itself automatically when build.cmd is run the first time. Note that this step is not required when using Visual Studio or msbuild directly.

  1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13: 14: 15: 16: 17: 18: 19: 20: 21: 22: 23:  build.cmd # normal build (.Net 4.0), run unit tests (.Net on Windows) ./build.sh # normal build (.Net 4.0), run unit tests (Mono on Linux/Mac, .Net on Windows) build.cmd Build # normal build (.Net 4.0) build.cmd Build incremental # normal build, incremental (.Net 4.0) build.cmd Build all # full build (.Net 4.0, 3.5, PCL) build.cmd Build net35 # compatibility build (.Net 3.5 build.cmd Build signed # normal build, signed/strong named (.Net 4.0) build.cmd Test # normal build (.Net 4.0), run unit tests build.cmd Test quick # normal build (.Net 4.0), run unit tests except long running ones build.cmd Test all # full build (.Net 4.0, 3.5, PCL), run all unit tests build.cmd Test net35 # compatibility build (.Net 3.5), run unit tests build.cmd Clean # cleanup build artifacts build.cmd Docs # generate documentation build.cmd Api # generate api reference build.cmd Zip # generate zip packages (.Net 4.0) build.cmd NuGet # generate NuGet packages (.Net 4.0) build.cmd NuGet all # generate normal NuGet packages (.Net 4.0, 3.5, PCL) build.cmd NuGet signed # generate signed/strong named NuGet packages (.Net 4.0) build.cmd All # build, test, docs, api reference (.Net 4.0) 

If the build or tests fail claiming that FSharp.Core was not be found, see fsharp.org or install the Visual F# 3.0 Tools directly.

## Dependencies

We manage NuGet and other dependencies with Paket. You do not normally have to do anything with Paket as it is integrated into our FAKE build tools, unless you want to actively manage the dependencies.

You can bootstrap or update Paket by calling tools/paket/paket.bootstrapper.exe. After bootstrapping, tools/paket/paket.exe restore will restore the packages to the exact version specified in the paket.lock file, tools/paket/paket.exe install will install or migrate packages after you have made changes to the paket.dependencies file, tools/paket/paket.exe outdated will show whether any packages are out of date and tools/paket/paket.exe update will update all packages within the defined constraints. Have a look at the Paket website for more commands and details.

## Documentation

This website and documentation is automatically generated from of a set of CommonMark structured files in doc/content/ using FSharp.Formatting. The final documentation can be built by calling build.sh Docs.

However, for editing and previewing the docs on your local machine it is more convenient to run build.sh DocsWatch in a separate console instead, which monitors the content files and incrementally regenerates the HTML output automatically. DocsWatch will also use local/relative URIs instead of absolute ones, so that the links and styles will work as expected locally. This can also be enabled in a full one-time build with build.sh DocsDev instead of just Docs.

## Creating a Release

While only maintainers can make official releases published on NuGet and referred to from the website, you can use the same tools to make your own releases for your own purposes.

Versioning is controlled by the release notes. Before building a new version, first add a new release header and change notes on top of the RELEASENOTES.md document in the root directory. The fake builds pick this up and propagate it to the assembly info files automatically.

The build can then be launched by calling:

 1: 2: 3:  build.sh All release # full release build build.sh NuGet release # if you only need NuGet packages build.sh Zip release # if you only need Zip packages 

The build script will print the current version as part of the the header banner, which is also included in the release notes document in the build artifacts. Example:

  1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13:  // __ __ _ _ _ _ ______ _______ // | \/ | | | | | | \ | | ____|__ __| // | \ / | __ _| |_| |__ | \| | |__ | | // | |\/| |/ _ | __| '_ \ | .  | __| | | // | | | | (_| | |_| | | |_| |\ | |____ | | // |_| |_|\__,_|\__|_| |_(_)_| \_|______| |_| // // Math.NET Numerics - https://numerics.mathdotnet.com // Copyright (c) Math.NET - Open Source MIT/X11 License // // Math.NET Numerics v3.5.0 // Math.NET Numerics MKL Provider v1.7.0 // Math.NET Numerics Data Extensions v3.1.0 

The artifacts are then ready in the out/packages directory.

## Extra Packages

In addition to the core package this repository also include extra packages like the MKL provider and the data extensions. Most build targets are available for these packages as well, with the following prefixes:

• Mkl for the MKL provider (MklWin or MklLinux if platform dependent)
• Data for the Data Extensions

Example: build.sh MklWinNuget release

## Official Release Process (Maintainers only)

• Update RELEASENOTES.md file with relevant changes, attributed by contributor (if external). Set date.

• Update CONTRIBUTORS.md file (via git shortlog -sn)

• Build Release:

 1:  build.sh All release 
• Commit and push release notes and (auto-updated) assembly info files with new "Release: v1.2.3" commit
• Publish Release:

 1: 2: 3: 4: 5:  build.sh PublishDocs build.sh PublishApi build.sh PublishTag build.sh PublishMirrors build.sh PublishNuGet 

In theory there is also a Publish target to do this in one step, unfortunately publishing to the NuGet gallery is quite unreliable.

• Create new GitHub release, attach Zip files (to be automated)
• Copy artifacts to release archive (to be automated)

• Consider a tweet via @MathDotNet

• Consider a post to the Google+ site

• Update Wikipedia release version and date for the Math.NET Numerics and Comparison of numerical analysis software articles.
