Libgit2Sharp is a managed wrapper around libgit2, and as such requires compilation of libgit2 for your platform.

LibGit2Sharp makes this easy by distributing, and leveraging as a dependency, the LibGit2Sharp.NativeBinaries NuGet package.

This package contains the compiled versions of the libgit2 native library for the following platforms:

  • Windows (x86/amd64)
  • Mac OS X (x86/amd64)
  • Linux (amd64)

Note: Due to the large number of distributions, the Linux support is currently experimental. Would you encounter any issue with it, please open an issue.

How to build your own native binaries

If you need to build your own native binaries for some reason, you can do so easily with the scripts in this repository:

  1. Clone the LibGit2Sharp.NativeBinaries repository. Do so recursively to ensure that the libgit2 submodule is initialized automatically:

    git clone --recursive

    (If you have already cloned this repository (which seems quite likely since you are reading this file!) then you can simply run git submodule init followed by git submodule update.)

  2. Update the included libgit2 sources and configuration files to the version of libgit2 you want to build. For example, to build commit 1a2b3c4:

    UpdateLibgit2ToSha.ps1 1a2b3c4

    Or you can specify references. To build the remote's master branch:

    UpdateLibgit2ToSha.ps1 master

  3. Build the libgit2 binaries. For Windows, this requires a Visual Studio installation, and will compile both x86 and amd64 variants. (See "Notes on Visual Studio", below). Run the build PowerShell script, specifying the version number of Visual Studio as the first argument. For example, to build with Visual Studio 2013 (aka "Visual Studio 12.0"):

    build.libgit2.ps1 12

    For Linux, this will build only the architecture that you're running (x86 or amd64). For Mac OS X, this will build a fat library that includes both x86 and amd64. Run the shell script:

  4. Create the NuGet package from the built binaries. You will need to specify the version number of the resultant NuGet package that you want to generate. Note that you may wish to provide a suffix to disambiguate your custom package from the official, published NuGet packages. For example, if you are building a product called fooproduct then that may be a helpful suffix.

    To build a NuGet package at version 1.2.3-foo:

    buildpackage.ps1 1.2.3-foo

    And the result will be a NuGet package in the current directory:


    Note that the -foo suffix technically makes this a "prerelease" package, according to NuGet, which may be further help in avoiding any mixups with the official packages, but may also require you to opt-in to prerelease packages in your NuGet package manager.

Specifying custom DLL names

If you want to redistribute a LibGit2Sharp that uses a custom libgit2, you may want to change the name of the libgit2 shared library file to disambiguate it from other installations. This may be useful if you are running as a plugin inside a larger process and wish to avoid conflicting with other plugins who may wish to use LibGit2Sharp and want to ensure that your version of libgit2 is loaded into memory and available to you.

For example, if your plugin names if fooplugin, you may wish to distribute a DLL named git2-fooplugin.dll. You can specify the custom DLL name as the second argument to the update and build scripts:

UpdateLibgit2ToSha.ps1 1a2b3c4 git2-fooplugin 14 git2-fooplugin

Then build the NuGet package as described above, making sure to provide a helpful suffix to ensure that your NuGet package will not be confused with the official packages.

Notes on Visual Studio

Visual Studio is required to build the native binaries, however you do not need to install a paid version of Visual Studio. libgit2 can be compiled using Visual Studio Community, which is free for building open source applications.

You need to specify the actual version number (not the marketing name) of Visual Studio. (For example, "Visual Studio 2013" is the name of the product, but its actual version number is "12.0".) A handy guide:

Marketing Name Version Number
Visual Studio 2010 10
Visual Studio 2012 11
Visual Studio 2013 12
Visual Studio 2015 14
Visual Studio 2017 15
You can’t perform that action at this time.
