"""
|
|
Waf tool for defining ardupilot's submodules, so that they are kept up to date.
|
|
Submodules can be considered dynamic sources, since they are updated during the
|
|
build. Furthermore, they can be used to generate other dynamic sources (mavlink
|
|
headers generation, for example). Thus, the correct use of this tool should
|
|
have three build groups: first one for updating the submodules, second for
|
|
generating any dynamic source from them, and the last one for the build. And
|
|
post_mode should be set to POST_LAZY. Example::
|
|
|
|
def build(bld):
|
|
bld.post_mode = waflib.Build.POST_LAZY
|
|
|
|
bld.add_group('git_submodules')
|
|
# gtest submodule
|
|
bld(
|
|
features='git_submodule'
|
|
git_submodule='gtest',
|
|
)
|
|
# mavlink submodule with syntactic sugar
|
|
bld.git_submodule('mavlink')
|
|
...
|
|
|
|
# now, for the dynamic sources
|
|
bld.add_group('dynamic_sources')
|
|
...
|
|
|
|
# now, below go the task generators for normal build process
|
|
bld.add_group('build')
|
|
...
