This is the --localstatedir that is found on other
buildsystems/programs + the package directory. We could provide a
--localstatedir instead to be similar to the others, but I thought it
would be too confusing for the help message.
In the end the build time is always almost the same, but it's a pain to
change one header and have it check the world. CI continues to use the
check so we can get any mistake before merging.
The original proposal was to add this functionality to the --upload option, but
it turns out that --upload seems something slightly different from what the
functionality added with patch does.
The issue motivating this patch is at
https://github.com/ArduPilot/ardupilot/issues/6283
Command for a local installation under BLD/install, where BLD is the build
variant. This will be useful for commands that depends on the install command.
That makes more sense, since that module is supposed to have basic Ardupilot
specific features. The root wscript should be a mere user of those features.
That way we avoid recompiling source files that don't depend on vehicles.
Change notes:
- UTILITY_SOURCE_EXTS: moved to ap_library
- Task generators indexes: ap_library handles that now and in a better way
- Use of AP_STLIB_FEATURES: it doesn't make sense anymore, since the stlib
taskgen has empty source list
- Flags and defines: passed down to ap_library through AP_LIBRARIES_OBJECTS_KW
- Set use='mavlink' in AP_LIBRARIES_OBJECTS_KW instead of calls to
bld.ap_stlib().
Otherwise, a call like `waf configure --board <foo> <command1>` will make
`<command1>` run on wrong variant if there was a different variant configured
previously, or an empty variant if the project is "distcleaned".
That makes it easier see what callbacks are or not being added and the order
they are executed. While at it, don't add build summary callback when in a
check command.
This allows to completely disable the tests. Even the gtest submodule is
not checked out allowing integration on build servers without needing to
download one more submodule.
This is different from the --notests flag. The latter only disables
executing the tests, but always use the submodule.
Waf's autoconfig feature works only for wscripts loaded by the recurse()
function. This patch extends that functionality to all loaded modules, which
includes Waf tools.
This is also needed while compiling libgtest because it's using our
cmath wrapper header. Otherwise it will end up entering the
"ifndef WAF_BUILD" part and fail to compile on gcc 5.3.1.
Setting the "help" keyword argument may not fit in one line sometimes. This
patch adds the following convention to calls to add_option() in order to
address that issue in a better way:
1) The "help" keyword must always be the last argument to be passed.
2) If the help string is a literal string or a literal string with some
operation (e.g. "%" operator) and setting the "help" keyword in the code
doesn't fit a line (considering the limit of characters in a line), then
the help string must be a triple-quoted string. That has the advantage of
not having to have several "+" operations for long help strings. In that
case, the help message must start on the next line and the closing
triple-quotes must be on a separate line together with the closing
parenthesis.
The requirement (1) makes it easier to make the style exception in (2)
acceptable.
The path for the "non-board" environment cache file was hard-coded, which was
causing the error below when the build was configured with the --out option
value different from the default path.
