Building for Windows

Build Prerequisites

Install mingw32

For Ubuntu 14.04:

sudo apt-get install mingw-w64

For older Ubuntu:

sudo apt-get install gcc-mingw32

Build Process

Cross-compile cjdns with the following command:

SYSTEM=win32 CROSS_COMPILE=i686-w64-mingw32- ./cross-do

Run-time Dependencies

On your Windows machine, you need the TAP driver installed to allow cjdns to create its virtual network interface. You can get it from the OpenVPN project at their main download page, under "Tap-windows", or use this direct link to version 9.9.2_3.

Check name of your new virtual connection it must contain only english letters or numbers


Once the TAP driver is installed, copy the cjdroute.exe file over to your windows machine.

Generate a configuration file with:

cjdroute --genconf > cjdroute.conf

You probably want to uncomment the "logTo":"stdout" line so that you can see any error messages in your terminal.

Then, execute cjdns from an elevated command prompt:

cjdroute --nobg < cjdroute.conf

The --nobg option is required; otherwise cjdns just quits.

The first time you start it, a Windows firewall dialog will probably pop up. Make sure to allow cjdns to accept connections from the Internet.

Next Steps

Congratulations! You are now running cjdns on Windows! Go find some peers!
