# WHAT IS THIS FILE?
|
|
# =============================================================================
|
|
#
|
|
# This is the master GN build configuration. This file is loaded after the
|
|
# build args (args.gn) for the build directory and after the toplevel ".gn"
|
|
# file (which points to this file as the build configuration).
|
|
#
|
|
# This file will be executed and the resulting context will be used to execute
|
|
# every other file in the build. So variables declared here (that don't start
|
|
# with an underscore) will be implicitly global.
|
|
|
|
# =============================================================================
|
|
# PLATFORM SELECTION
|
|
# =============================================================================
|
|
#
|
|
# There are two main things to set: "os" and "cpu". The "toolchain" is the name
|
|
# of the GN thing that encodes combinations of these things.
|
|
#
|
|
# Users typically only set the variables "target_os" and "target_cpu" in "gn
|
|
# args", the rest are set up by our build and internal to GN.
|
|
#
|
|
# There are three different types of each of these things: The "host"
|
|
# represents the computer doing the compile and never changes. The "target"
|
|
# represents the main thing we're trying to build. The "current" represents
|
|
# which configuration is currently being defined, which can be either the
|
|
# host, the target, or something completely different (like nacl). GN will
|
|
# run the same build file multiple times for the different required
|
|
# configuration in the same build.
|
|
#
|
|
# This gives the following variables:
|
|
# - host_os, host_cpu, host_toolchain
|
|
# - target_os, target_cpu, default_toolchain
|
|
# - current_os, current_cpu, current_toolchain.
|
|
#
|
|
# Note the default_toolchain isn't symmetrical (you would expect
|
|
# target_toolchain). This is because the "default" toolchain is a GN built-in
|
|
# concept, and "target" is something our build sets up that's symmetrical with
|
|
# its GYP counterpart. Potentially the built-in default_toolchain variable
|
|
# could be renamed in the future.
|
|
#
|
|
# When writing build files, to do something only for the host:
|
|
# if (current_toolchain == host_toolchain) { ...

#
|
|
# This block lists input arguments to the build, along with their default
|
|
# values.
|
|
#
|
|
# If a value is specified on the command line, it will overwrite the defaults
|
|
# given in a declare_args block, otherwise the default will be used.
|
|
#
|
|
# YOU SHOULD ALMOST NEVER NEED TO ADD FLAGS TO THIS FILE. GN allows any file in
|
|
# the build to declare build flags. If you need a flag for a single component,
|
|
# you can just declare it in the corresponding BUILD.gn file.
|
|
#
|
|
# - If your feature is a single target, say //components/foo, you can put
|
|
# a declare_args() block in //components/foo/BUILD.gn and use it there.
|
|
# Nobody else in the build needs to see the flag.
|
|
#
|
|
# - Defines based on build variables should be implemented via the generated
|
|
# build flag header system. See //build/buildflag_header.gni. You can put
|
|
# the buildflag_header target in the same file as the build flag itself. You
|
|
# should almost never set "defines" directly.
|
|
#
|
|
# - If your flag toggles a target on and off or toggles between different
|
|
# versions of similar things, write a "group" target that forwards to the
|
|
# right target (or no target) depending on the value of the build flag. This
|
|
# group can be in the same BUILD.gn file as the build flag, and targets can
|
|
# depend unconditionally on the group rather than duplicating flag checks
|
|
# across many targets.
|
|
#
|
|
# - If a semi-random set of build files REALLY needs to know about a define and
|
|
# the above pattern for isolating the build logic in a forwarding group
|
|
# doesn't work, you can put the argument in a .gni file. This should be put
|
|
# in the lowest level of the build that knows about this feature (which should
|
|
# almost always be outside of the //build directory!).
|
|
#
|
|
# Other flag advice:
|
|
#
|
|
# - Use boolean values when possible. If you need a default value that expands
|
|
# to some complex thing in the default case (like the location of the
|
|
# compiler which would be computed by a script), use a default value of -1 or
|
|
# the empty string. Outside of the declare_args block, conditionally expand
|
|
# the default value as necessary.
|
|
#
|
|
# - Use a name like "use_foo" or "is_foo" (whatever is more appropriate for
|
|
# your feature) rather than just "foo".
|
|
#
|
|
# - Write good comments directly above the declaration with no blank line.
|
|
# These comments will appear as documentation in "gn args --list".
|
|
#
|
|
# - Don't call exec_script inside declare_args. This will execute the script
|
|
# even if the value is overridden, which is wasteful. See first bullet.
