Currently, if we run "meson configure -Doption=value", meson will
do a reconfigure when running "ninja build" afterwards, even if
the new value is the same one that was already configured previously.
To avoid this unnecessary reconfigure, let's use replace_if_different()
instead of unconditionally replacing the conf file in coredata's save()
function.
custom_target allows selective installation if it outputs more than one
file. Mention this explicitly in install.
Additionally, fix the types for install_dir.

(b, name) will always have the canonical tool name, not just a
potentially weird bin path. We need to check stderr for qt4 tools other
than lrelease, but we keyed off of the tool bin path, so matches were by
no means guaranteed, and specifically, would fail if the tool is looked
up via bindir.
This really should always have checked the canonical name, which is
guaranteed to be correct.
Partial fix for #10443
This forces the use of the Apple archiver, since that archiver doesn't
add extern'd variables to the symbol table automatically, and instead
requires that ranlib be used. A native file is used to ensure that
Apple's ar is used even in the presence of llvm or gcc in the path with
their superior archivers.

Apple's AR is old, and doesn't add externed symbols to the symbol table,
instead relying on the user calling ranlib with -c. We need to do that
for the user
In commit 4ca9a16288 we added unreliable
support (it warns you if you try it) for gcc-compatible treatment of
uppercase-C files being C++ instead of C. In order to handle it
correctly, we needed to evaluate can-compile by special-casing "C" to
avoid lowercasing it for comparisons.
This didn't cover all cases where we check if "C" is a C++ language
file. We also straight-up check the language of a file (rather than
working backwards to see if a C++ compiler can compile it) when doing
module scanning, and this needs to special-case "C" as well.
We also had one case where we only checked lowercase fortran extensions,
but not lowercase C++ extensions. While we are at it, use lowercase for
C++ as well, except the "C" special case.
Fixes#10629
If this command fails, for example when CXX is something not generic
enough to be a valid universal compiler command (clang -std=c++11
perhaps), we end up with two problems:
- it's impossible to figure out what Meson ran to get that error
- the error report isn't clear on what is stdout and what is stderr, or
even that that is what the message is about.
```
meson.build:1:0: ERROR: Unable to get clang pre-processor defines:
error: invalid argument '-std=c++11' not allowed with 'C'
```
What's C doing there and why is Meson talking about it? Answer: that's
compiler stdout. Say so.
We do something similar when running get_compiler() method checks from
the DSL. This ensures that if errors happen, the log file we tell people
to check actually works.
Ninja backend will fail to find the vs dep dependency
prefix string in a mingw64 environment. This change
simply updates the regex to be able to capture mingw64's unique
file separation pattern.
When `self.wrap.filesdir` is a relative path, which happens when
`meson subprojects update` is run, the path to the patch must be
provided relative to the working directory in which `patch` or `git`
is run.
`self.wrap.filesdir` is absolute when `Resolve()` is invoked by the
Meson interpreter, which is why this wasn't detected by the tests.
It saves bandwidth and disk usage on downloaded subprojects, and people
very rarely need more than the single commit they’re using.
Add `depth=1` to the `[wrap-git]` examples in the rest of the
documentation, to make it more likely that people will copy-and-paste it
into their `.wrap` files.

Specifically, this is a combination of the following:
- Revert "visualstudio.py: Apply /utf-8 only on clang or VS2015+"
This reverts commit 6e7c3efa79.
- Revert "Visual Studio: Only use /utf-8 on VS2015 or later or clang-cl"
This reverts commit 8ed151bbd7.
The changes were broken and untested, although this is because of a lack
of general CI testing for all languages on Windows. At least, this broke
the use of ifort, and possibly more.
The changes are fundamentally a bit "exciting", as they step out of the
hierarchy of compiler definitions and apply arguments almost willy-nilly.
And apparently it's leaky all over the place. I don't understand all of
what is going on with it, but it plainly failed to achieve its desired
goal and needs to be rolled back ASAP.
This enables the fortran tests for Azure.
We only test on x64, because:
- ifort isn't arm64 compatible
- x86 may in theory exist, but Meson reports it cannot compile
executables
These checked that e.g. the cpp and fc ids are identical, which isn't
strictly what we want. Particularly, msvc doesn't even have a fortran
compiler, and what we really care about is whether we mix both gcc and
something else.
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.
