gyp (1)

gyp [options] [build_file...]

Uses the specified build files to generate build scripts or project files in the current platform\(cqs native format. If no build file is specified, all files in the current directory with a .gyp suffix are used.

-D<variable>=<value>

Provide a default value for the given variable. This supplements settings from the GYP_DEFINES environment variable, which should be a space-separated list of <variable>=<value> pairs.

-f<format>[(,<format>)...], --format=<format>[(,<format>)...]

Generate output in the formats listed. Valid formats include make (GNU makefile), xcode (Xcode project file), msvs (Visual Studio project file), scons (SCons rule set), and gypd (gyp input, for debugging).

Defaults to the value of the GYP_GENERATORS environment variable, which should be a comma-separated list of formats, or the platform\(cqs native format if unset (xcode for Mac OS X, msvs for Windows, including Cygwin, make for other Unix).

-I<path>, --include=<path>

Implicitly include the contents of the <path> file in all loaded .gyp files.

--depth=<path>

For Chromium, the gyp "depth" variable should always be a relative path to Chromium\(cqs top-level src directory. This option allows one to specify a path the DEPTH variable should be set relative to.

Defaults to the first directory named src found as an ancestor of one of the build files passed on the command line.

-d<debug mode>, --debug=<debug mode>

Turn on debugging output. Valid debugging modes include "general" to list options used, "variables" to trace variable expansion, and "includes" to trace build file include directives.

-S<suffix>, --suffix=<suffix>

Insert the specified string in the names of generated files before the standard extension. For example, with the make backend and a suffix of ".foo", gyp will write the main makefile to Makefile.foo and target-specific snippets to target.foo.mk.

-G<flag>=<value>

Set a "generator flag", which is an option specific to the particular output format. All generator flags have names beginning with the name of the output format. This supplements the GYP_GENERATOR_FLAGS environment variable, which should be a space-separated list of <flag>=<value> pairs.

--generator-output=<dir>

Write the generated build files under the <dir> directory and adjust paths accordingly. This allows building in a separate directory from the source files.

This overrides the GYP_GENERATOR_OUTPUT environment variable.

--ignore-environment

Do not read options from environment variables.

--check

Take extra time to verify the syntax of each build_file.

--parallel

Use multiprocessing for speed (experimental).

--toplevel-dir=<dir>

Directory to use as the root of the source tree.

--build=<configs>

Configuration for build after project generation.

--no-circular-check

Disable the check for circular relationships between .gyp files. These relationships should not exist, but they\(cqve only been observed to be harmful with the Xcode output format. Chromium\(cqs .gyp files currently have some circular relationships on non-Mac platforms, so this option allows the strict behavior to be used on Macs and the lenient behavior to be used elsewhere.

This option is likely to be removed once all circular relationships in Chromium are eliminated.

GYP_DEFINES, GYP_GENERATORS, GYP_GENERATOR_FLAGS, GYP_GENERATOR_OUTPUT

See the -D, --format, -G, and --generator-output options.

~/.gyp/include.gypi

Implicitly included before anything else in every .gyp file.
