A simple tool to integrate protocol buffers into your build system.
|
||||
|
||||
Example for C++:
|
||||
|
||||
def configure(conf):
|
||||
conf.load('compiler_cxx cxx protoc')
|
||||
|
||||
def build(bld):
|
||||
bld(
|
||||
features = 'cxx cxxprogram'
|
||||
source = 'main.cpp file1.proto proto/file2.proto',
|
||||
includes = '. proto',
|
||||
target = 'executable')
|
||||
|
||||
Example for Python:
|
||||
|
||||
def configure(conf):
|
||||
conf.load('python protoc')
|
||||
|
||||
def build(bld):
|
||||
bld(
|
||||
features = 'py'
|
||||
source = 'main.py file1.proto proto/file2.proto',
|
||||
protoc_includes = 'proto')
|
||||
|
||||
Example for both Python and C++ at same time:
|
||||
|
||||
def configure(conf):
|
||||
conf.load('cxx python protoc')
|
||||
|
||||
def build(bld):
|
||||
bld(
|
||||
features = 'cxx py'
|
||||
source = 'file1.proto proto/file2.proto',
|
||||
protoc_includes = 'proto') # or includes
|
||||
|
||||
|
||||
Example for Java:
|
||||
|
||||
def options(opt):
|
||||
opt.load('java')
|
||||
|
||||
def configure(conf):
|
||||
conf.load('python java protoc')
|
||||
# Here you have to point to your protobuf-java JAR and have it in classpath
|
||||
conf.env.CLASSPATH_PROTOBUF = ['protobuf-java-2.5.0.jar']
|
||||
|
||||
def build(bld):
|
||||
bld(
|
||||
features = 'javac protoc',
|
||||
name = 'pbjava',
|
||||
srcdir = 'inc/ src', # directories used by javac
|
||||
source = ['inc/message_inc.proto', 'inc/message.proto'],
|
||||
# source is used by protoc for .proto files
|
||||
use = 'PROTOBUF',
|
||||
protoc_includes = ['inc']) # for protoc to search dependencies
|
||||
|
||||
|
||||
Protoc includes passed via protoc_includes are either relative to the taskgen
|
||||
or to the project and are searched in this order.
|
||||
|
||||
Include directories external to the waf project can also be passed to the
|
||||
extra by using protoc_extincludes
|
||||
|
||||
protoc_extincludes = ['/usr/include/pblib']
|
||||
|
||||
|
||||
Notes when using this tool:
|
||||
|
||||
- protoc command line parsing is tricky.
|
||||
|
||||
The generated files can be put in subfolders which depend on
|
||||
the order of the include paths.
|
||||
|
||||
Try to be simple when creating task generators
|
||||
containing protoc stuff.
