The previous diagnosis (that the wrapper that injects the -target
option to clang caused the issues) doesn't seem right; the issue
was that LLD's MinGW frontend (which is invoked when ld.lld is given
a COFF argument to the -m option) didn't handle the --version argument
before LLD 9.0.0.
PR #6363 made it so our interpretation of env vars no longer clashed
with Autoconf's: if both Meson and Autoconf would read and env var, both
would do the same things with the value they read.
However, there were still cases that autoconf would read an env var when
meson wouldn't:
- Autoconf would use `CC` in cross builds too
- Autoconf would use `CC_FOR_BUILD` in native builds too.
There's no reason Meson can't also do this--if native cross files
overwrite rather than replace env vars, cross files can also overwrite
rather than replace env vars.
Because variables like `CC` are so ubiquitous, and because ignoring them
in cross builds just makes those builds liable to break (and things more
complicated in general), we bring Meson's behavior in line with
Autoconf's.
This makes use of proper ConfigTool and PkgConfig dependencies rather
than one big ExternalDependency that internally creates other
dependencies and then copies their attributes.
Basically this breaks down into three cases. An open source version with
compliant PkgConfig, valid CMake, and a Intel implementation that has
completely broken PkgConfig. For the first two cases we can use standard
classes, for the last we can make a subclass of PkgConfigDependency that
handles the special logic.
This doesn't change any of the logic, but it does re-organize it to be
clearer, and make use of the dependency factory API, which makes other
things (like Dependency.get_variable) work.
This is untested with Intel MKL.
This make relative pathes shorter an too give a chance to
de-duplicate -isystem flags just like -I flags.
Fix common test case 203 for OSX build host too
If no exe_wrapper is set in the meson cross file the exe_wrapper
object will be an instance of EmptyExternalProgram.
So, found is True and prorgram is an empty list.
This will cause meson to tun the compiler sanity check because
it checks only for self.is_cross and self.exe_wrapper being
not None.
I ran into that situation while cross compiling for ia32 on a
x64_64 host. The host had no ia32 userspace installed, so the
self test failed.
As workaround I currently set exe_wrapper to 'true'.

getattr() requires a default (return if missing) value or it raises an
AttributeError. In a few cases I changed hasattr to getattr and didn't
set a default value, so those cases could except. This corrects that.
Clang supports the GCC -Og flag, but --optimization=g is not setting that. This is because Clang is referencing the clike_optimization_args, which does not define a flag for 'g'.
To address this, we'll mimic the GNU options instead of the C-like ones.
Fixes#6619
This should have worked before, but the inheritance order was backwards,
so we got the DCompiler before the GnuCompiler, and the base Compiler
methods overrode the Gnu methods.
Some compilers that act as linker drivers (dmd and ldc) need to split
arguments that GCC combines with , (ie, -Wl,-foo,bar -> -L=-foo -L=bar).
As such we need to detect that the previous argument contained -soname,
and not wrap that in a --start-group/--end-group
This modifies the shared library test to demonstrate the problem, with a
test case.
Fixes#6359
It may not be obvious to users that these two ways to set build-types
override each other and specifying both is redundant, and conflicts
are resolved based on whichever is specified later.

With the current logic passing `--debug` will actually be parsed as
`-Ddebug=false`, which is absolutely not what is expected.
There is no case in which the presence of a boolean option in `--foo`
form will mean 'I want feature foo disabled', regardless of the
*default* value of that option.
Also includes a test.
Closes https://github.com/mesonbuild/meson/issues/4686
The previous code was assuming that options do not depend on each
other, and that you can set defaults using `dict.setdefault()`. This
is not true for `buildtype` + `optimization`/`debug`, so we add
defaults + overrides in the right order and use the options parsing
code later to compute the values.
Includes a test.
Closes https://github.com/mesonbuild/meson/issues/6752
This ensures that options are always parsed in the order in which they
were specified on the command-line, even with Python 3.5, and
non-CPython implementations compatible with CPython 3.5 and 3.6.

This is the argument to name the implib when using the Visual Studio
Linker. This is needed by LDC and DMD when using link.exe or
lld-link.exe on windows, and is really a linker argument not a compiler
argument.
[why]
Sometimes one want to set the 'Conflicts:' field in .pc files.
This is possible by using the 'conflicts' keyword argument in the
pkgconfig module. The feature is not documented on mesonbuild.org,
though.
But a warning is issued:
WARNING: Passed invalid keyword argument "conflicts".
WARNING: This will become a hard error in the future.
History:
It has been added along with kwarg 'url' with commit
309041918 pkgconfig: Add missing 'URL' and 'Conflicts' entries
Later the kwargs check has been introduced with
80d665e8d Converted some modules.
but both 'url' and 'conflicts' were missing.
With commit
2acf737b pkgconfig: Document url keyword
the 'url' kwarg has been added to the checks, but not 'conflicts'.
[how]
Add 'conflicts' to the allowed kwargs.
