 # Common Build Tasks
 
 The Chromium build system is a complicated beast of a system, and it is not very
 well documented beyond the basics of getting the source and building the
 Chromium product. This page has more advanced information about the build
 system.
 
 If you're new to Chromium development, read the
 [getting started guides](https://www.chromium.org/developers/how-tos/get-the-code).

 ### Mac: DCHECKs in Release Mode
 
 DCHECKs are only designed to be run in debug builds. But building in release
 mode on Mac is significantly faster. You can have your cake and eat it too by
 building release mode with DCHECKs enabled using the following define:
 
     $ GYP_DEFINES="dcheck_always_on=1" gclient runhooks
 
 ### Linux

 ## Configuring the Build
 
 ### Environment Variables
 
 There are various environment variables that can be passed to the metabuild
 system GYP when generating project files. This is a summary of them:

     $ GYP_DEFINES="branding=Chrome buildtype=Official" gclient runhooks
 
 Then building the `chrome` target will produce the official build. This tip can
 be used in conjunction with changing the output directory, since changing these
 defines will rebuild the world.
 
 Also note that some GYP\_DEFINES flags are incompatible with the official build.
 If you get an error when you try to build, try removing all your flags and start
 with just the above ones.
