Compiling Mono on Windows

There are two ways of building Mono on Windows, both do require a Cygwin setup which provides some tools required by Mono at build time. First, download Cygwin from Use the 32 bit installer (setup-x86.exe).

Run the following command in cmd.exe to install the required packages:

setup-x86.exe --root "C:\cygwin" --quiet-mode --packages autoconf,automake,bison,gcc-core,gcc-g++,mingw64-i686-runtime,mingw64-i686-binutils,mingw64-i686-gcc-core,mingw64-i686-gcc-g++,mingw64-i686-pthreads,w32api-headers,libtool,make,python,gettext-devel,gettext,intltool,libiconv,pkg-config,git,curl,libxslt

At this point, you can either do a Visual Studio build or you can continue reading the instructions for a Cygwin build.

The following steps assume you’re running in an instance of the Cygwin terminal. Pick an installation directory where you want your new copy of Mono to be installed. Lets call that location PREFIX. Your Mono installation and its dependencies will be installed there.

Building Mono from a Release Package

Mono releases are distributed as .tar.bz2 packages from the Mono web site. Once you have your dependencies installed all you need to do is run the following command where VERSION is the package version number and PREFIX is your installation prefix:

tar xvf mono-$VERSION.tar.bz2
cd mono-$VERSION
./configure --prefix=$PREFIX --host=i686-w64-mingw32
make install

By the end of this process, you will have Mono installed on your PREFIX directory.

Building Mono From a Git Source Code Checkout

To build Mono from a Git Source Code checkout, you will want to have the official Mono installed on the system and in your PATH, as the build requires a working C# compiler to run.

On Windows, you should set the following Git setting to avoid issues with line endings: git config --global core.autocrlf input

Once you do this, run the following commands, remember to replace PREFIX with your installation prefix that you selected:

git clone
cd mono
./ --prefix=$PREFIX --host=i686-w64-mingw32
make install
