When changing meson option cpp_eh, it was passed to cl with AdditionalOptions and resulted in unsuppressable warning "cl : command line warning D9025: overriding '/EHs' with '/EHa'"
- vcpkg libraries are not found when given cmake_toolchain_file and vcpkg_target_triplet as cmake_args when looking for the dependency if the first call to cmake has different arguments. The libraries are found if the first call has same arguments or if the CMakeCache.txt is deleted in call_with_fake_build.
This is needed in the case where a custom_target directly depends on a
shared library, and somehow loads it.
(Specifically this can be the case with gtkdoc, when it invokes
gtkdoc-scangobj, which will build and run it's own code to load a shared
library, to introspect it)
Handle command arguments which contain multiple substitutions correctly
in Backend.eval_custom_target_command()
In particular, gnome.gtkdoc() makes arguments of the form '--cflags
-I@SOURCE_ROOT@ -I@BUILD_ROOT' (where these arguments are then passed
down to a compiler invocation)
Normally, these are subsequently made right by
NinjaBackend.replace_paths(), but if Backend.as_meson_exe_cmdline()
decides that the command needs to be pickled, that doesn't happen.
(Although having two places where this substitution might happen smells
really bad)
Since we parse buildoptions.json to pass options, we end up passing
-Dbuildtype and also -Doptimization and -Ddebug which triggers the
warning:
WARNING: Recommend using either -Dbuildtype or -Doptimization + -Ddebug [...]
Filter out buildtype. It is redundant.
Otherwise we can end up finding dependencies from the build machine for
the host machine, which is incorrect. This alters cmake, pkg-config, and
all config-tool based dependencies.
Fixes: #7276
it really doesn't make sense to put this in the ExternalDependency
class. It doesn't rely on any of the state of that class, and it's
generically useful inside meson.
Causes spammy warnings from the linker:
ld: warning: -headerpad_max_install_names is ignored when used with -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES)
so: when building compile args, meson is deduplicating flags. When a
compiler argument is appended, a later appearance of a dedup'ed is going
to remove a earlier one. If the argument is prepended, the element
*before* the new one is going to be removed. And that is where the
problem reported in https://github.com/mesonbuild/meson/pull/7119 is
coming in. In the revision linked there, the order of replacement in the
prepend case was revesered.
With this patch, we restore this behaviour again.
When meson is currently being run with a python that seems to have been
installed from the Windows Store, replace the general WindowsApps
directory in search paths with dirname(sys.executable), and also handle
failures with pathlib.resolve on WindowsApps exe files.
Use the IDE's OpenMP flag instead of adding /openmp to additional
arguments. The IDE appears to override /openmp in additional arguments
with the IDE setting, which defaults to false, leading to binaries built
without OpenMP.
The linker that comes with MSVC does not understand the /openmp flag.
This results in a string of
LINK : warning LNK4044: unrecognized option '/openmp'; ignored
warnings, one for each static_library linked with an executable.
Avoid this by only setting the linker openmp flag when the compiler is
not MSVC.
