Hacking on the GN binary itself

Building GN itself

GN is part of the Chromium tree, in //tools/gn/. If you have a Chromium checkout, you already have the source and you can do ninja -C out/Debug gn to build it.

To build gn using gn, run (in the root src directory):

gn gen out/Default
ninja -C out/Default gn

Change out/Default as necessary to put the build directory where you want.

Running GN's unit tests

ninja -C out/Default gn_unittests && out/Default/gn_unittests
