Revert "Divide sources between targets and add include paths to them"

This reverts commit 382f5ef962f649b083344a31ecd6fe955fd1e146.

Reason for revert: causes some source files to be missing from the
generated Xcode project. This makes developing on Chrome on iOS
difficult (as files are not found by indexing, nor search in files,
it is not possible to put breakpoint in them, ...).

Original change's description:
> Divide sources between targets and add include paths to them
> Autocomplete in Xcode not works if we have all sources in one target,
> at least in big projects.
> So we add a few types of targets: static and dynamic libraries, with
>  them, generated project better represent the internal structure of
> the project. Also, we do not add all sources to one target, we spread
> them between targets, where they should be.
> Also, we add include paths to targets.

GN is a meta-build system that generates build files for Ninja.

Getting a binary

You can download the latest version of GN binary for Linux, macOS and Windows.

Alternatively, you can build GN from source:

git clone
cd gn
python build/
ninja -C out
# To run tests:

On Windows, it is expected that cl.exe, link.exe, and 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 CC, CXX, and AR.


There is a simple example in examples/simple_build directory that is a good place to get started with the minimal configuration.

To build and run the simple example with the default gcc compiler:

cd examples/simple_build
../../out/gn gen -C out
ninja -C out

For a maximal configuration see the Chromium setup:

and the Fuchsia setup:

Reporting bugs

If you find a bug, you can see if it is known or report it in the bug database.

Sending patches

GN uses Gerrit for code review. The short version of how to patch is:

Register at

... edit code ...
ninja -C out && out/gn_unittests

Then, to upload a change for review:

git commit
git push origin HEAD:refs/for/master

The first time you do this you'll get an error from the server about a missing change-ID. Follow the directions in the error message to install the change-ID hook and run git commit --amend to apply the hook to the current commit.

When revising a change, use:

git commit --amend
git push origin HEAD:refs/for/master

which will add the new changes to the existing code review, rather than creating a new one.
