[xcode] Fix running XCTests and XCUITests with New Build System A hack was used to allow Xcode to associate source files with the test module and correctly find the list of tests without builing the app first. This hack breaks when using the New Build System as Xcode tries to build those files and complains about missing output files. As it prevents from running the tests, disable the hack when using the New Build System. Bug: chromium:1103230 Change-Id: I70e3b359af4f27a2a3af8bd2a339187e1b9d916c Reviewed-on: https://gn-review.googlesource.com/c/gn/+/9300 Reviewed-by: Brett Wilson <brettw@chromium.org> Commit-Queue: Sylvain Defresne <sdefresne@chromium.org>
GN is a meta-build system that generates build files for Ninja.
Related resources:
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.
To build and run the simple example with the default gcc compiler:
cd examples/simple_build ../../out/gn gen -C out ninja -C out ./out/hello
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 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.
