Don't use a nested scope for BUILDCONFIG. The change bac5bd0 ("Do not use the root scope for BUILDCONFIG.gn.") introducted a nested scope into BUILDCONFIG.gn processing. But this means that the build config file can't modify the default scope which is its whole purpose. This removes the nested scope and modifies the directory during execution of the build config file which was the goal of the above change.

Alternatively, you can build GN from source:
git clone https://gn.googlesource.com/gn cd gn python build/gen.py ninja -C out # To run tests: out/gn_unittests
On Windows, it is expected that
lib.exe can be found in
PATH, so you'll want to run from a Visual Studio command prompt, or similar.
On Linux and Mac, the default compiler is
clang++, a recent version is expected to be found in
PATH. This can be overridden by setting
There is a simple example in examples/simple_build directory that is a good place to get started with the minimal configuration.
For a maximal configuration see the Chromium setup:

If you find a bug, you can see if it is known or report it in the bug database.
GN uses Gerrit for code review. The short version of how to patch is:
Register at https://gn-review.googlesource.com. ... edit code ... ninja -C out && out/gn_unittests
Then, to upload a change for review:
git commit git cl upload --gerrit
When revising a change, use:
git commit --amend git cl upload --gerrit
which will add the new changes to the existing code review, rather than creating a new one.
