Building Pidgin-Encryption on WindowsBuilding this is a bit of a pain, especially if you haven't used Cygwin/MinGW before. If you'd prefer, check out the pre-built self-extracting installer.
Ooh, you're really gonna build it yourself! Cool...
Start with the Pidgin building instructions here.
Put the Pidgin-Encryption source release into pidgin/plugins.Build/install it:
make -f Makefile.mingw install
There you go. It will (hopefully) work exactly the same as the Linux version.
If you want to build the installer, you will need to include several DLLs from NSPR and NSS into the pidgin/win32-install-dir, before you run make -f Makefile.mingw installer in the root pidgin directory.
