[webkit-dev] ninja build available for chromium/mac, empty builds up to 20x as fast

[Nico Weber]

Hi,

we recently made the webkit/chromium/mac port buildable with ninja, a
new build system focused on build speed
(http://martine.github.com/ninja/). I don't have any numbers for
webkit standalone builds, but in a chromium checkout ninja is 20x as
fast as make on empty builds (1s instead of 20s), and 120x as fast as
xcodebuild.

Giving it a try is easy:

  Tools/Scrips/update-webkit --chromium --ninja
  Tools/Scripts/build-webkit --chromium

The output will appear in out/Release (or out/Debug if you do a debug build).

Nico

ps: If anybody is doing standalone webkit/chromium/linux builds: It's
very easy to make that work with ninja, too.
