This removes one line of stderr output per GObject Introspection file
processed, e.g.
g-ir-scanner: link: gcc -o Fwupd-2.0 Fwupd-2.0.o -L. -Wl,-rpath...
This error message was quite confusing when triggered by
use of an absolute path to the include dir of an external dependency
(numpy in my case). Changing that to a relative dir also isn't
a solution, because Meson will *not* do the "busywork to make paths
work" that the error message says it will.
Transpilers need to run on the build machine in order to generate their
output, which can then be taken by a cross-compiler to create the final
output.
For the same reasons commit 7aa28456d ("Add dependency type for
Valgrind") removed linking with valgrind, pkgconfig shouldn't generate
"Requirements" for it, in general.

MachineChoice is a mesonlib object, not a compilers object, so it makes
no sense to import it from the latter simply because the latter imports
it too. This results in brittle module dependencies and everything
breaking when a refactor removes it from the latter.
... also it is a typing-only import so while we are fixing it to import
from the right place, we can also put it in a type-checking block.
This is undefined behaviour, and seems to have caused test failures
when backporting Meson to an older toolchain in the Steam Runtime.

We want to talk about the kwargs to the custom_target() function, but
tried to link to custom_tgt instead, which is not a function. It is an
object, but this was the wrong reference method for a type.
We want the function anyway, so use that.
The end of the paragraph indicates that the options which support --foo
will be listed in the help text. The beginning of the paragraph seems to
suggest the same thing, except it doesn't distinguish between -Dfoo and
--foo style options.
The first mention is redundant and feels like the wrong part of the
paragraph to mention it anyway.
With the previous commit, we made this smartly detect when parentheses
are not needed. But the example was broken, because it doesn't follow
its own documented rules to use `[[#` syntax. Add the missing hash
character.
If we link to
```meson
[[#function]]('posarg')
```
then the ideal linkification would operate on "function" in the
formatted text:
```
function('posarg')
```
Instead, it operated on "function()" in the formatted text:
```
function()('posarg')
```
Fix this by detecting the next character after the reference, and
skipping the usual "automatically append the () for you" stage if it
already has that opening parenthesis.
The old implementation assumed a path is of Windows iff the second
character is a colon. However, that is not always true.
First, a colon can be included in a non-Windows path. For example, it is
totally fine to have a directory named ':' on Linux 5.17.0 tmpfs.
Second, a Windows path may start with \\ for UNC or extended length.
Use pathlib to handle all of these cases.
Regardless of which MachineChoice we base the platform on, we compare
its value to lowercased identifiers. So we need to lowercase the
targetplatform too... but we only did so sometimes.
This broke e.g. on "Win32", but only when *not* doing a cross build.
Fixes#10539
We have to handle this, because Windows needs to link to the implib of
the executable (???) in order to create a shared module. This is
explicitly checked for and handled in the backend, and creating a build
target with `link_with: some_exe` still works, even. But updating
declare_dependency to typed_kwargs neglected to take that into account,
so creating a convenience interface for those same arguments failed.
In PR 10263, we didn't account for that we may have initialize the Visual
Studio-like compiler two times, once for a C compiler and once for the
C++ compiler, so we end up with Meson breaking on Visual Studio 2013
or earlier, such as when building GLib.
Fix this by setting up the always_args member of
the VisualStudioLikeCompiler instance during __init__() as needed, so that
we avoid falling into modifying shared objects.
In commit 3dcc712583 we moved to
typed_pos_args. In the process, we deleted some code to specifically
raise an error if you use custom_target or generator outputs, instead
leaving it out of the typed pos args.
However, that support was specifically supposed to be there. It was only
an error in part of an if statement for handling old versions of
glib-compile-resources. The specific error it calls out is that we need
to manually parse the depfile at configure time, due to an external bug;
obviously this is impossible if the gresource is only created at build
time.
Reinstate the original error message check, and allow built outputs to
be used as compile_resources() inputs.
Fixes#10367
The check for if the project supports the -j flag was needlessly
complex. We support two types of project:
- waf, always supports -j
- make, if GNU, supports -j
We never checked waf, and the make check assumed that the entire
command, rather than just the last component, was "make". It also
neglects "gmake".
Since any possible build command *may* support -j, always run the
--version check. Detect either build command in the output.
The unit test was racy but surprisingly never failed on CI. The reason
is we need to ensure ninja build somelib.so before running `make` into
the external project.
