CultureSpy worked out how to compile cjdns for Windows for Windows. So if you happen to use this broken ass OS and want to use cjdns....

Building cjdns On Windows For Windows

Install Cygwin from here

Extra packages to install, if they're not installed by default:

gcc-core
gcc-g++
libltdl7
mingw-binutils
mingw-gcc-core
mingw-pthreads
mingw-w32api
mingw64-i686-binutils
ming64-i686-gcc
ming64-i686-gcc-core
ming64-i686-gcc-g++
ming64-i686-headers
ming64-i686-pthreads
ming64-i686-runtime
ming64-i686-windows-default-manifest
ming64-i686-winpthreads
python
w32api-headers
w32api-runtime
windows-default-manifest
make

Install node.js

Get the cjdns source

Create C:\tmp

Start a cygwin session and update your environment for mingw compilation:

export CC=i686-w64-mingw32-gcc
export CXX=i686-w64-mingw32-g++

Make a small edit to the cjdns JS build system:

--- a/node_build/make.js
+++ b/node_build/make.js
@@ -43,7 +43,7 @@ Builder.configure({
     systemName:     SYSTEM,
     crossCompiling: process.env['CROSS'] !== undefined,
     gcc:            GCC,
-    tempDir:        '/tmp',
+    tempDir:        'C:\\tmp',
     optimizeLevel:  '-O2',
     logLevel:       process.env['Log_LEVEL'] || 'DEBUG'
 }, function (builder, waitFor) {

(that is, replace the line that says tempDir: '/tmp' with tempDir: 'C:\\tmp')

This works around an issue with the detection of the tmp directory.

Also, make sure libuv will build:

cp node_build/dependencies/libuv/Makefile.mingw node_build/dependencies/libuv/Makefile

Edit node_build/dependencies/libuv/Makefile so that it will use the mingw gcc instead of the cygwin gcc:

15c15
< CC = gcc
---
> #CC = gcc

(That is, comment out the line that sets the CC variable.)

Then run ./do to build

The system churns for a while, hopefully producing no errors. It will eventually tell you it's time to run cjdroute. It lies.

cp build_win32/admin_angel_cjdroute2_c.exe cjdroute.exe

Or put cjdroute.exe wherever you like.

And obviously secure your shit
