= Introduction =

OpenVPN Windows releases include a Windows GUI, which is not part of the core project. OpenVPN versions 2.2.x and earlier include the [http://openvpn.se old Windows GUI], whereas 2.3 and later include the [http://sourceforge.net/projects/openvpn-gui/ new Windows GUI]. These instruction cover building the new GUI, although instruction for the old one are probably very similar.

= Building the OpenVPN installer bundle =

Currently the easiest way to build OpenVPN-GUI is to build the entire OpenVPN Windows installer bundle and extract the produced OpenVPN-GUI binary. Thorough instructions are available [https://community.openvpn.net/openvpn/wiki/BuildingUsingGenericBuildsystem here].

= Building OpenVPN-GUI =

'''NOTE:''' These instructions are probably outdated. Please fix them or use the process described above.

== Installing prequisites ==

=== MinGW ===

If you're building the OpenVPN-GUI on Windows, you need to install [http://www.mingw.org/ MinGW] first, as both OpenSSL and OpenVPN-GUI are built with it.

=== OpenSSL ===

Build and install OpenSSL using the MinGW instruction given [BuildingOnWindows#BuildingOpenSSL here].

== Building OpenVPN-GUI ==

Launch a MinGW command prompt and descend to the OpenVPN-GUI source directory. From there, issue the following commands:

{{{
$ autoreconf -v
$ ./configure --with-crypto-includes=/c/openssl/include --with-crypto-lib=/c/openssl/lib
$ make
}}}

This assumes you installed the OpenSSL files to that location. This will create a ''openvpn-gui.exe'' file into the build directory. You can simply launch this executable and it should work, provided that OpenVPN is installed.
