This project provides a work-in-progress standalone version of the toolchains and configs used by the Chromium project.

The toolchains have been tested on the following platforms:

• Windows (MSVC 2013/2015/Clang 3.8)
• FreeBSD (GCC 5 / Clang 3.7)
• Linux (GCC 5 / Clang 3.7)

• is_debug (default: true): Enable/disable debugging options.
• is_clang (default: false): Favor Clang over the platform default (GCC/MSVC).
• use_lld (default: false): Use the new LLD linker. This requires is_clang to be true.

• visual_studio_version (default: 2013): The MSVC version to use.
• visual_studio_path (default: auto-detected): The path of your MSVC installation. Autodetected based on visual_studio_version.
• windows_sdk_path (default: auto-detected): Path of your Windows SDK installation.
• win_clang_prefix (default: ""): If is_clang is true, this is required to point to the directory containing the clang-cl executable.

• gcc_cc (default: gcc): Path of the GCC C compiler executable. Does not have to be absolute.
• gcc_cxx (default: g++): Path of the GCC C++ compiler executable. Does not have to be absolute.
• gcc_version (default: auto-detected): Version of the GCC compiler. Format: major * 10000 + minor * 100 + patchlevel
• clang_cc (default: gcc): Path of the Clang C compiler executable. Does not have to be absolute.
• clang_cxx (default: g++): Path of the Clang C++ compiler executable. Does not have to be absolute.
• clang_version (default: auto-detected): Version of the Clang compiler. Format: major * 10000 + minor * 100 + patchlevel

TODO: Mac builds are currently unsupported.

Fork this repo and add it as a submodule/DEPS-entry to your project. This way you can modify every part of the //build directory while still being able to easily merge upstream changes (e.g. support for new GN features that you don't want to implement yourself.)
