"""This script wraps gyp and sets up build environments.
|
|
|
|
Build instructions:
|
|
|
|
1. Setup gyp: ./gyp_packager.py or use gclient runhooks
|
|
|
|
clang is enabled by default, which can be disabled by overriding
|
|
GYP_DEFINE environment variable, i.e.
|
|
"GYP_DEFINES='clang=0' gclient runhooks".
|
|
|
|
Ninja is the default build system. User can also change to make by
|
|
overriding GYP_GENERATORS to make, i.e.
|
|
"GYP_GENERATORS='make' gclient runhooks".
|
|
|
|
2. The first step generates the make files but does not start the
|
|
build process. Ninja is the default build system. Refer to Ninja
|
|
manual on how to do the build.
|
|
|
|
Common syntaxes: ninja -C out/{Debug/Release} [Module]
|
|
Module is optional. If not specified, build everything.
|
|
|
|
Step 1 is only required if there is any gyp file change. Otherwise, you
|
|
may just run ninja.
