Using check_statement() with an empty statement just to check for the
header is quite a hack. Fix check_headers() (so it takes a "use"
parameter), and use it for the checks instead.
We need to manually define the flag since we are using a separate identifier
for each of the Lua checks. This was done before 9b45b48 by the composed check
with a define_key (see waftools/checks/generic.py).
The pkg-config check was the only one to not redefine a define key because Waf
already does that automatically when we call the generated function with the
same identifier as the generator function. Now if they are called with two
different arguments we will get two different definitions.
Fixes#1218
This wraps waf's find_program in our own check boilerplate code so that it
can be used in the declarative dependencies section of the wscript.
Can be used like this:
}, {
'name': 'sed',
'desc': 'sed program',
'func': check_program('sed', 'SED'),
}, {
First argument is the program name, and the second is the waf variable name
where the program path will be stored. In this example we will be able to
refer to sed with ${{SED}} when creating waf Tasks in wscript_build.
/cc @giselher: I think you need this for wayland-scanner.
This prevents waf from running test programs after compilation. A better
approach would be to only remove this option if the check actually errors,
but we are using this only for Lua anyway.
waf apparently only appends a pkgconfig flag if it doesn't already exist in
the lib storage. Since our configure often checks for multiple libraries in
one call we want to keep the flags as is. This is especially important to
always keep stuff like -lm in the right place.
This commit adds a new build system based on waf. configure and Makefile
are deprecated effective immediately and someday in the future they will be
removed (they are still available by running ./old-configure).
You can find how the choice for waf came to be in `DOCS/waf-buildsystem.rst`.
TL;DR: we couldn't get the same level of abstraction and customization with
other build systems we tried (CMake and autotools).
For guidance on how to build the software now, take a look at README.md
and the cross compilation guide.
