How to compile statically linked OpenVPN client for ARMv5

How to compile statically linked OpenVPN client for ARMv5

You need to install ARMv5 gcc cross compiler: apt-get install gcc-arm-linux-gnueabi

You have to define a directory (via --prefix) where all of your binaries will be installed (copied). In the guide I use the following: /home/user/vpn_compile

OpenSSL

  1. Download the source: wget https://www.openssl.org/source/openssl-1.0.2j.tar.gz
