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 ​old Windows GUI, whereas 2.3 and later include the ​new Windows GUI. These instruction cover building the new GUI, although instruction for the old one are probably very similar.

Installing prequisites

MinGW

If you're building the OpenVPN-GUI on Windows, you need to install ​MinGW first, as both OpenSSL and OpenVPN-GUI are built with it.

OpenSSL

Build and install OpenSSL using the MinGW instruction given 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.
