Building CEF3 with Ninja on OS X

[nathansobo]

I'm trying to get CEF3 building on OS X with Ninja because it's much faster for incremental compiles.

I set GYP_DEFINES=ninja and ran the gclient hooks to generate a ninja build in src/out/Debug and src/out/Release. I am able to build the libcef target, but when I try to build cefclient, I get the following warning and error:

ninja: WARNING: multiple rules generate cef_unittests.app/Contents/Frameworks/Chromium Embedded Framework.framework/Resources/locale.pak. build will not be correct; continuing anyway
ninja: ERROR: 'obj/cef/cefclient.gen/repack/zh_TW.lproj/locale.pak', needed by 'cefclient.app/Contents/Frameworks/Chromium Embedded Framework.framework/Resources/locale.pak', missing and no known rule to make it

I saw a changelog with a patch to CEF 1 to get it building with ninja on OS X (haven't tried that). Has anyone managed to get CEF3 building with ninja?

Thanks.

This is a known problem. It may be necessary to change CEF's GYP files so that they play nice with Ninja, or perhaps to fix the Ninja GYP generator.

I've managed to use Ninja for a build on OS X.

Above problem can be worked around by manually building the cef_locales target and then in the src/out/Debug/obj/cef directory, copy or link cef_locales.gen to cefclient.gen. You'll only need to do this when the localized strings changed.

Another problem is that the current cef.gyp wasn't fixing the Framework link correctly. After line 461, in "xcode_settings" section of the "libcef" target, add something like "'DYLIB_INSTALL_NAME_BASE':'@executable_path',".

Please note that I'm using the trunk of cef3.
