OpenVPN 2.4.4 setup for a Steam Link

Tested on ubuntu server 16.04 with generic dev tools (TODO: document setup from fresh install)

General Setup

Within a work folder:

• Download the Steam Link SDK
• $ source steamlink-sdk/setenv.sh
• $ export PREFIX=<work folder>/deps
• $ export CROSS=armv7a-cros-linux-gnueabi

Set up LZO

• $ wget http://www.oberhumer.com/opensource/lzo/download/lzo-2.09.tar.gz
• $ tar xzf lzo-2.09.tar.gz && cd lzo-2.09
• $ ./configure $STEAMLINK_CONFIGURE_OPTS --enable-static --prefix=$PREFIX
• $ make && make install

At this point you should have some files in <work folder>/deps.

Set up OpenSSL

• $ wget https://www.openssl.org/source/openssl-1.0.2j.tar.gz
• $ tar xzf openssl-1.0.2j.tar.gz && cd openssl-1.0.2j
• $ ./Configure gcc no-ssl2 no-shared -static --prefix=$PREFIX --cross-compile-prefix=$CROSS-
• $ make && make install

Set up OpenVPN

• $ wget https://swupdate.openvpn.org/community/releases/openvpn-2.4.4.tar.gz
• $ tar xzf openvpn-2.4.4.tar.gz && cd openvpn-2.4.4
• $ sed -i -e 's/\/dev\/net\/tun/\/dev\/tun/g' src/openvpn/tun.c (this is bad, but I wasn't able to get the --dev-node to work properly when the utility is built normally.
• $ ./configure --target=$CROSS --host=$CROSS --prefix=$PREFIX --disable-server --enable-static --disable-shared --disable-debug --disable-plugins OPENSSL_SSL_CFLAGS="-I$PREFIX/include" OPENSSL_SSL_LIBS="-L$PREFIX/lib -lssl" OPENSSL_CRYPTO_CFLAGS="-I$PREFIX/include" OPENSSL_CRYPTO_LIBS="-L$PREFIX/lib -lcrypto" LZO_CFLAGS="-I$PREFIX/include" LZO_LIBS="-L$PREFIX/lib -llzo2" IFCONFIG=/bin/ifconfig ROUTE=/bin/route
• $ make LIBS="-all-static" && make install

At this point a working openvpn binary for your steam link should exist at deps/sbin/openvpn.
