gi-docgen is supposed to be ran natively on the build machine, without
native: true dependency() searches for gi-docgen on the host system.
When it doesn't find it, it falls back to a subproject even if gi-docgen
is available on the build machine.
also make gtk_doc require introspection
Sysprof has a new -Dagent=true build option which allows installing a
/usr/bin/sysprof-agent program (simimlar to sysprof-cli). It provides a
P2P D-Bus API to the process which can control subprocesses. It's used by
IDE tooling to have more control across container boundaries.
However, we do not need it for GTK CI.
The GdkToplevelSize struct already has the concept of "bounds", which
means the largest size a window should reasonably have. It's practically
the equivalent of the monitor the window is intended to be mapped on,
with the "struts" (e.g. panels) cut out. It's used by GTK to use this
information to calculate a default window size that is "lagom" (swedish;
not too large, not too small).
Meson knows all private dependencies itself when passing the library as
first positional argument, no need to specify them manually. Also
simplify backend specific files by simply requiring gtk4, just like
unix-print already did.
This should fix generated gtk4-uninstalled.pc, see Meson bug report:
https://github.com/mesonbuild/meson/issues/10415
Ensure that resolution of the subproject occurs via the dependency
interface, not the "poke at subprojects manually" interface, and make
that actually work via --wrap-mode=forcefallback.
There's no need to mark it as not-required and then manually invoke
subproject(), since fallback should work correctly and it is always
needed.
However, if fallback was performed (or forced) it would error out since
get_variable() was instructed to only use pkg-config while the relevant
variable was exported by the subproject as an internal fallback
dependency.
One may be using IJG libjpeg or libjpeg-turbo to build GTK, and their
build files may or may not generate pkg-config files for us. To make
things easier, we can make use of CMake's built-in support for finding
IJG libjpeg or libjpeg-turbo.
The CMake build files for libtiff may or may not generate pkg-config
files for us, so we can use Meson's CMake support to help us find
libtiff, as CMake has built-in support for finding libtiff.
Add a variable in meson.build that covers Visual Studio-like compilers,
so that we can use it to help us find depedencies using CMake rather
than via pkg-config, where applicable.
Change the existing use case for finding libpng accordingly.
From the GCC manpage:
> Wimplicit-fallthrough=5 doesn't recognize any comments as

So, check for the =5 version after checking for the simple version. This
way we get -Wfallhrough with clang and -Wfallthrough -Wfallthrough=5
with GCC, which works.
This makes the hotspot of DND surfaces work when using the Vulkan and
OpenGL renderers.
This bumps the CI image used to the newly built image. This is needed to
install a new enough libwayland-client.so needed for wl_surface.offset.
This is done by adding wayland as a meson subproject, building it
on-demand if the version in the system is not new enough. As
libwayland-client.so is pulled in implicitly when linking to gtk4, the
compile step needs LD_LIBRARY_PATH set to make ld find the right library
to link to.
Without building the demos, nothing gets installed into $prefix/share/icons/hicolor. Which makes running
`gtk4-update-icon-cache` on the machine causes an error. This is easily reproducible on a Windows machine with MSVC where
there is nothing pre-installed on hicolor icon theme and that makes building gtk without the demos fails with "No such file or directory".
I forgot to remove the '-Werror=' part from all the extra warnings, so
the warning/error flags we generated were '-Werror=-Werror=warning-flag'
or 'W-Werror=warning-flag' - but because our compiler flag checking
infrastructure works so nicely, it just ignored these obviously wrong
flags.
Fixes commit 362e91c40b
Do kep them for debug and debugoptimized builds though.
Keeping -Werror flags in release builds causes issues with forward
compatibility, when new compiler releases or different toolchains
suddenly cause those warnings to be emitted during compilation.
While we certainly want those issues to be investigated and fixed, they
should not prevent anyone from building GTK until they are.
Resolves#4388
On Visual Studio-style builds, it is likely that we do not have pkg-config
files for libpng, so improve the search for libpng by using CMake's built-in
mechanisms for looking for libpng. This, however, means that we need to use
'png' rather than 'libpng' for the package name to search for.
Add support for the tiff format, which is flexible
enough to handle all our memory texture formats
without loss.
As a consequence, we are now linking against libtiff.
Using libpng instead of the lowest-common-denominator
gdk-pixbuf loader. This will allow us to load >8bit data,
and apply gamma and color correction in the future.
For now, this still just provides RGBA8 data.
As a consequence, we are now linking against libpng.
Basically, I was building some packages on Guix. I figured out that
wayland-protocols was listed among propagated-inputs for gtk+ package
(gtk-3-24). propagated-inputs holds a list of runtime dependencies,
that should be available to any other package that depends on gtk+.
While discussing we clarified that wayland-protocols is not runtime
dependency. So I moved it to native-inputs of gtk+ package, which
means that, this dependency will be available only to gtk+ package and
only at build time. Once moved, building of other applications that
depening on gtk+ started to fail.
Investigation showed that, all .pc (pkg-config) files prepared by gtk+
package, was including:
Requires.private: ... wayland-protocols ...
Since it becomes requirement, other applications was failing with
missing dependency wayland-protocols of dependency gtk+, for instance:
-- Checking for module 'gtk+-3.0'
-- Package 'wayland-protocols', required by 'gdk-3.0', not found
While actually wayland-protocols is not even a build time dependency
of application that depends on gtk+. Advertisement of such
requirement, is a bit misleading, because one does not need it at
runtime, especially applications based on gtk.
