The tool needs to run the preprocessor (but does not actually produce
compiled outputs), and meanwhile ignores lots of flags it doesn't think
it needs. In the case of -D_FORTIFY_SOURCE=... this is only valid if -O
is there too, but otherwise spits out confusing warnings.
The warnings are spurious and can be safely ignored, but in this case
let's go the extra mile and fix g-ir-scanner's upstream bug by removing
the fortify flag first.
Fixes#9161
When sending them to the introspection scanner, we must always filter
all compiler and linker flags, because g-ir-scanner does not accept any
random argument but only a specific subset.
Fixes: #8876
g-ir-scanner does not convert relative -L paths to runtime paths which
are added to -Wl,-rpath and LD_LIBRARY_PATH / DYLD_LIBRARY_PATH
/ PATH. This means that the local library will either not be found at
runtime (while building introspection data), or the system-wide
library will be picked instead.
See: giscanner/ccompiler.py:get_internal_link_flags() in
gobject-introspection for more details.
This commit introduces a new type of `HoldableObject`: The
`SecondLevelHolder`. The primary purpose of this class is
to handle cases where two (or more) `HoldableObject`s are
stored at the same time (with one default object). The
best (and currently only) example here is the `BothLibraries`
class.
We need to pass any generated sources down the CustomTarget
inititalizers so that they will generate a dependency correctly,
otherwise we get race conditions.
install_scripts used to replace @BUILD_ROOT@ and @SOURCE_ROOT@ but it
was not documented and got removed in Meson 0.58.0. gnome.gtkdoc() was
relying on that behaviour, but it has always been broken in the case the
source or build directory contains spaces.
Fix this by changing get_include_args() to substitue paths directly
which will then get escaped correctly.
Add a unit test that builds GObject documentation which is where this
issue has been spotted.
Fixes: #8744
Cross-compiling and generating gobject-introspection isn't trivial, but
with wrapper scripts that call qemu-user it's perfectly doable[1].
Currently looking up the gobject-introspection pkgconfig is done as a
native dependency, which means in cross-compilation environments this
is not the right paths (wrong library path, for example).
Solve this by generalisiing _get_native_dep() to _get_dep(native) and
asking for the host gobject-introspection instead.

Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.
Fixes: #2550.
Re-implement it in backend using the same code path as for
custom_target(). This for example handle setting PATH on Windows when
command is an executable.
Various GNOME projects have scripts that does similar task, better do it
directly in meson. This ensures it's done correctly regarding usage of
subprojects and pkg-config. See for example this gtk bug:
https://gitlab.gnome.org/GNOME/gtk/-/issues/3626.
Fixes: #8268
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
Fixes: #8187
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.

`volatile` was previously mistakenly used in GLib to indicate that a
variable was accessed atomically or otherwise multi-threaded. It’s not
meant for that, and up to date compilers (like gcc-11) will rightly warn
about it.
Drop the `volatile` qualifiers.
Based on a patch by Jeff Law.

It's an easy mistake to do this:
gir1 = gnome.generate_gir(...)
gir2 = gnome.generate_gir(...
includes: ['GObject-2.0', gir1])
This fails with an error:
ERROR: Gir includes must be str, GirTarget, or list of them.
The issue is that the 'gir1[0]' should be passed instead of 'gir1'.
To make the problem slightly clearly, tweak the error message to be:
ERROR: Gir includes must be str, GirTarget, or list of them. Got TypelibTarget.
When glib is a subproject we should use glib-compile-resources it
overrides using find_program() in the case it is not installed on the
build machine. With old glib version we have to run
glib-compile-resources at configure time to generate the list of
dependencies, but not when glib is recent enough.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
This gives the version that the feature was deprecated in, and doesn't
print the warning if the project supports versions of meson in which the
project wasn't deprecated.
This revert a part of #7020 because it was using gir_inc_dirs
before it is set. Properly fix typelib_includes instead that was working
only when g-i is a pkgconfig dependency.
This makes the typing annotations basically impossible to get right, but
if we only have one key then it's easy. Fortunately python provides
comprehensions, so we don't even need the ability to pass multiple keys,
we can just [extract_as_list(kwargs, c) for c in ('a', 'b', 'c')] and
get the same result.
These are basically doing what mlog.log(..., once=True) does, so lets
just use that. The once argument to mlog is newer, so these probably
should have been changed already.
listify shouldn't be unholdering, it's a function to turn scalar values
into lists, or flatten lists. Having a separate function is clearer,
easier to understand, and can be run recursively if necessary.
