Process transitive dependecies for externs When generating Rust externs, we need to handle both direct and transitive dependencies i.e. dependencies coming from public deps. Bug: crbug.com/gn/105 Change-Id: I6bc89358f8c42f1cf1fc0e3527516c13b5a9f842 Reviewed-on: https://gn-review.googlesource.com/c/gn/+/5820 Commit-Queue: Petr Hosek <phosek@google.com> Reviewed-by: Brett Wilson <brettw@chromium.org>
GN is a meta-build system that generates build files for Ninja. There is documentation in docs/ and a presentation on it.
You can download the latest version of GN binary for Linux, macOS and Windows.
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 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.
For a maximal configuration see the Chromium setup:
and the Fuchsia 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.
