初次下载(支持断点续传)：

fetch --no-history chromium

编译后，拉取全部history

git fetch --unshallow 

git fetch --shallow-since=15/11/2012

Build options

https://www.chromium.org/developers/gn-build-configuration/

is_debug = false

Component build

The component build links many parts of Chrome into separate shared libraries to avoid the long link step at the end. It is the default when compiling debug non-iOS builds and most developers use this mode for everyday builds and debugging. Startup is slower and some linker optimizations won't work, so don't do benchmarks in this mode. Some people like to turn it on for release builds to get both faster links and reasonable runtime performance.

is_component_build = true

Faster builds with no or minimal symbols

The symbol_level setting varies from 0 (no symbols or minimal symbols) to 2 (full symbols).

symbol_level = 0

Disable Native Client

Most developers don't normally need to test Native Client capabilities and can speed up the build by disabling it.

enable_nacl = false

Remove WebCore symbols

WebCore has lots of templates that account for a large portion of the debugging symbols. If you're not debugging WebCore, you can set the blink symbol level to 0 or 1:

blink_symbol_level=0

Remove v8 symbols

v8 is often the second-largest source of debugging symbols. If you're not debugging v8, you can set the v8 symbol level to 0 or 1:

v8_symbol_level=0

Windows

There is a gn gen argument (--ide) for producing Visual Studio project and solution files:

$ gn gen out\mybuild --ide=vs
