Since `build_always` also adds a target to the set of default targets,
this option is marked deprecated in favour of the new option
`build_always_stale`.
`build_always_stale` *only* marks the target to be always considered out
of date, but does *not* add it to the set of default targets.
The old behaviour can still be achieved by combining
`build_always_stale` with `build_by_default`.
fixes#1942
This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.
We say 'different dependencies support different values for this', but
nowhere document what values are supported, so the only way to find these
out is to read the source, or guess. Make a start at doing that.
Refine #3277
According to what I read on the internet, on OSX, both MH_BUNDLE (module)
and MH_DYLIB (shared library) can be dynamically loaded using dlopen(), but
it is not possible to link against MH_BUNDLE as if they were shared
libraries.
Metion this as an issue in the documentation.
Emitting a warning, and then going on to fail during the build with
mysterious errors in symbolextractor isn't very helpful, so make attempting
this an error on OSX.
Add a test for that.

Since f3ff8fe6 (0.39.0), this has a common implementation with the same
substitution in generators, but I think they existed earlier.
@BASENAME@ is used internally by the custom target generated by
windows.compile_resources()
* docs/reference-manual: link to references tables
Currently the reference manual entries for *machine.cpu_family() and
*machine.system() have incomplete (and wrong) information. Rather than
continue to duplicate this information just link to the reference
tables.
* docs/Reference-manual: fix link target
The IDs in hotdoc are always lowered, so this pointed to the right page,
but didn't go to the heading.
* docs/Reference-manual: link compiler.get_id directly to tables
Currently it goes round about to an entry that doesn't add much
information and points to the reference table. Instead just point to the
reference table.
Mention that the dependency name will also be searched for as a framework on
OSX.
Note that additional dependency-specific keywords may be used by custom
dependency lookup.
To maintain backward compatibility we cannot add recursive objects by
default. Print a warning when there are recursive objects to be pulled
and the argument is not set. After a while we'll do pull recursive
objects by default.
This adds a new method, partial_dependency to all dependencies. These
sub dependencies are copies of the original dependency, but with one or
more of the attributes replaced with an empty list. This allows creating
a sub dependency that has only cflags or drops link_arguments, for
example.
The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
Sometimes it is needed to run the current compiler with specific options
not to compile a file but rather to obtain additional info. For example,
GCC has several -print-* options to query it about the paths to
different libraries and development files. One use case is to get the
location of development files for GCC plugins, which is not easily
obtainable by other means:
gcc -print-file-name=plugin
For this purpose, it would be convenient if the compiler object returned
by meson.get_compiler(lang) could be used in run_command() directly.
This commit implements it.

The documentation doesn't require it and the interpreter code works around the
possibility of it being None. The ninja backend code however fails with
File "/home/whot/code/meson/mesonbuild/backend/ninjabackend.py", line 796, in generate_data_install
dstabs = os.path.join(subdir or None, plain_f)
File "/usr/lib64/python3.6/posixpath.py", line 78, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
If install_dir is missing, default to datadir/projectname
After PR #2662, running test case common/125 shared module/ on Cygwin gets
me:
$ ninja -C _build
ninja: Entering directory `_build'
[7/7] Linking target prog.exe.
/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: warning: --export-dynamic is not supported for PE+ targets, did you mean --export-all-symbols?
Also, fix doc for correct version of first apperance.
Future work: Notwithstanding the hint that ld gives, these options are not
equivalent, and it's not clear we should be using it here:
--export-all-symbols is the default behaviour, and if the exports are
restricted by explicit annotations or a .def file, this option might be
overriding that...
