|
# This file is meant to be included into a target to provide a rule
|
|
# to invoke protoc in a consistent manner.
|
|
#
|
|
# To use this, create a gyp target with the following form:
|
|
# {
|
|
# 'target_name': 'my_proto_lib',
|
|
# 'type': 'static_library',
|
|
# 'sources': [
|
|
# 'foo.proto',
|
|
# 'bar.proto',
|
|
# ],
|
|
# 'variables': {
|
|
# # Optional, see below: 'proto_in_dir': '.'
|
|
# 'proto_out_dir': 'dir/for/my_proto_lib'
|
|
# },
|
|
# 'includes': ['path/to/this/gypi/file'],
|
|
# }
|
|
# If necessary, you may add normal .cc files to the sources list or other gyp
|
|
# dependencies. The proto headers are guaranteed to be generated before any
|
|
# source files, even within this target, are compiled.
|
|
#
|
|
# The 'proto_in_dir' variable must be the relative path to the
|
|
# directory containing the .proto files. If left out, it defaults to '.'.
|
|
#
|
|
# The 'proto_out_dir' variable specifies the path suffix that output
|
|
# files are generated under. Targets that gyp-depend on my_proto_lib
|
|
# will be able to include the resulting proto headers with an include
|
|
# like:
|
|
# #include "dir/for/my_proto_lib/foo.pb.h"
|
|
#
|
|
# If you need to add an EXPORT macro to a protobuf's c++ header, set the
|
|
# 'cc_generator_options' variable with the value: 'dllexport_decl=FOO_EXPORT:'
|
|
# e.g. 'dllexport_decl=BASE_EXPORT:'
|
|
#
|
|
# It is likely you also need to #include a file for the above EXPORT macro to
|
|
# work. You can do so with the 'cc_include' variable.
|
|
# e.g. 'base/base_export.h'
|
|
#
|
|
# Implementation notes:
|
|
# A proto_out_dir of foo/bar produces
|
|
# <(SHARED_INTERMEDIATE_DIR)/protoc_out/foo/bar/{file1,file2}.pb.{cc,h}
|
|
# <(SHARED_INTERMEDIATE_DIR)/pyproto/foo/bar/{file1,file2}_pb2.py
