Building ======== If you want to build the tun/tap drivers, make sure you have Apple's Developer Tools installed. Then from the top of the tun/tap source tree issue # make This will build the driver kexts and place them as tap.kext and tun.kext in the top tun/tap directory. You can install these two kexts directly in /Library/Extensions. As root, you can simply say # make install_kext Otherwise OS X will refuse to load the extensions. After that, they can be loaded using kextload: # kextload /Library/Extensions/tap.kext/ kextload: /Library/Extensions/tap.kext/ loaded successfully # kextload /Library/Extensions/tun.kext/ kextload: /Library/Extensions/tun.kext/ loaded successfully If you want to have the extensions loaded at boot time, use the startup items provided in the directory startup_items. This can be done using the Makefile (as root): # make install_scripts I have also included the files used to build the installer packages in the directory pkg. They can be made by # make pkg This is all I have to say at the moment, feel free to mail me any bug reports, problems and suggestions you have at .
