5 # This file is meant to be included into a target to provide a rule
6 # to invoke protoc in a consistent manner. For Java-targets, see
7 # protoc_java.gypi.
8 #
9 # To use this, create a gyp target with the following form:
10 # {
11 # 'target_name': 'my_proto_lib',
12 # 'type': 'static_library',
13 # 'sources': [
14 # 'foo.proto',
15 # 'bar.proto',
16 # ],
17 # 'variables': {
18 # # Optional, see below: 'proto_in_dir': '.'
19 # 'proto_out_dir': 'dir/for/my_proto_lib'
20 # },
21 # 'includes': ['path/to/this/gypi/file'],
22 # }
23 # If necessary, you may add normal .cc files to the sources list or other gyp
24 # dependencies. The proto headers are guaranteed to be generated before any
25 # source files, even within this target, are compiled.
26 #
27 # The 'proto_in_dir' variable must be the relative path to the
28 # directory containing the .proto files. If left out, it defaults to '.'.
29 #
30 # The 'proto_out_dir' variable specifies the path suffix that output
31 # files are generated under. Targets that gyp-depend on my_proto_lib
32 # will be able to include the resulting proto headers with an include
33 # like:
34 # #include "dir/for/my_proto_lib/foo.pb.h"
35 #
36 # If you need to add an EXPORT macro to a protobuf's c++ header, set the
37 # 'cc_generator_options' variable with the value: 'dllexport_decl=FOO_EXPORT:'
38 # e.g. 'dllexport_decl=BASE_EXPORT:'
39 #
40 # It is likely you also need to #include a file for the above EXPORT macro to
41 # work. You can do so with the 'cc_include' variable.
42 # e.g. 'base/base_export.h'
43 #
44 # Implementation notes:
45 # A proto_out_dir of foo/bar produces
46 # <(SHARED_INTERMEDIATE_DIR)/protoc_out/foo/bar/{file1,file2}.pb.{cc,h}
47 # <(SHARED_INTERMEDIATE_DIR)/pyproto/foo/bar/{file1,file2}_pb2.py
