FeatureCheck always immediately sets extra_message to '' if it isn't
explicitly passed, so there is really no point in using None as a
sentinel that is never used.
Names used in init functions are sometimes pointlessly different from
the class instance attributes they are immediately assigned to. They
would make more sense if defined properly.
Originally name should have been set to required=True, but since then
the requirement to name CustomTargets (which compile_resources is a
wrapper around) has been dropped. As such we just need to allow the
default value of None through.
Fixes: #9698
Make it possible to specify a wrapper for executing binaries
in cross-compiling scenarios.
(usually, some kind of target hardware emulator, such as qemu)
They passed the arguments in the wrong order, so the version parsed as the
message and the message parsed as a version.
While we are at it, pass the location node in too.
We allow this for the command (the first parameter), but not later
parameters, which is just odd. This also allows us to give better error
messages for the case of overridden programs.
This also cleans up a couple of internal callers of the internal impl
version that don't set the `check` argument, and therefore trigger a
warning about not setting the check argument.
The interpreter tries to catch any exception and add the latest node
information to it, but currently we only used that to print better
formatted error messages on MesonException.
Since we should theoretically have that property for most/all
exceptions, let's percolate that upward, and message the user that an
unexpected traceback was encountered, that it should be reported as a
bug, and the helpful information of "how far into parsing this
meson.build did we get before erroring out, anyway?"
If the compiler check is updated as a string in meson.build, we force
rebuild, which is a good thing since the outcome of that check changes
the configuration context and can enable or disable parts of the build.
If the compiler check came from a files() object then we didn't add a
regen rule on those files.
Fixes#1656
For libraries installed to libdir, it's not expected to have rpath
hooked up. But for non-default libdirs, the path might not get searched
by default. `ldconfig -m <libdir>` is convenient here, as it will
programmatically add a new directory to search for shared libraries, so
the resulting installed programs work out of the box.
Include the dragonfly BSD platform name, which doesn't match the 'bsd'
catch-all pattern.
has_function(prefix: '...') is useless to check the difference between
builtins and external library functions. It has code to detect
"builtins" that misfires and reports that iconv_open is defined as a
builtin on mingw, but only if you include the header.
Instead compile an open-coded test file that this iconv dependency
implementation fully controls, that doesn't get up to imaginative edge
cases like trying to find `__builtin_iconv_open`.
Fixes commit db1fa702f3, which merely
moved the brokenness over one step to the right (by breaking mingw
instead of freebsd)

They don't utilize a soname cache, so running ldconfig without arguments
is basically pointless -- and at least some of them are buggy: running
ldconfig with the verbose flag switches on "delete all directories from
the hints file, and recreate it using 0 command-line positional
arguments", which would soft-brick the system.
Fixes#9592
This header is required anyway. And the compile test for linking to libc
with the iconv_open symbol, can succeed when we try to use the literal
symbol name without includes, but fail later during project build,
because actually including iconv.h might redefine the function to match
a forked symbol. This happens when GNU iconv is installed as a
standalone library on systems that have a less fully-featured iconv
implementation.
So, by including the header in has_function, we ensure that we test
against the default resolved header. In the event that the symbol which
is #define'd by the header is 'libiconv_open', linking will fail against
libc even when a builtin iconv does exist, and we will fall back to the
iconv dependency that provides -liconv (and which is needed to properly
use the default header).
Fixes compiling against the iconv dependency on e.g. FreeBSD when the
libiconv port is installed.
Emit a detailed deprecation warning that explains what to do instead.
Also add a unittest.
```
DEPRECATION: target prog links against shared module mymod, which is incorrect.
This will be an error in the future, so please use shared_library() for mymod instead.
If shared_module() was used for mymod because it has references to undefined symbols,
use shared_libary() with `override_options: ['b_lundef=false']` instead.
```

This previously worked because we were accidentally doing this via
mutation. However, doing this via mutation is not a good way to do it,
we should be explicit.
Fixes#9542
This ensures that there is no warnings when running meson on
test cases/common/22 object extraction.

Make the handling of bindgen inputs consistent with the inputs and outputs of
source_strings_to_files.
However, for the first source argument reject anything that cannot
possibly be an header file. This also fixes a mypy failure from the next
patch, since ExtractedObjects does not have a zero-argument get_outputs
method.

As evidenced by the warning message immediately below this, I meant to
write "5.15" here. As is, this will enable depfile support on too-old
versions of moc.
