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.
That's a sneaky trick so my edit/compile/test cycle goes faster:
I usually use demos for testing so the tools don't have to be linked for
me to start testing.
It's only used during DND to allow use of the root window's cow window
as a DND target, because apparently gnome-shell used to think that was a
great idea to DND to the overview.
Somebody complain to gnome-shell devs about it not being a good idea if
they want it fixed.
Potentially using Wayland is a better idea though.

It's not 2011 anymore, and we shouldn't randomly build one of 10.000
different combinations of X11 backends (I counted the possibilities) but
exactly the one we expect people to use.
Instead, ensure that sassc is made madatory on git builds (because
it is, we don't ship CSS files anymore) and not even looked for in
release builds (because do ship CSS files there).
We hardcoded the typelib directory for only an arch (and a distro),
while we can just get it from gobject-introspection pkg config if tests
are enabled.
We can't use this flag for any code that may get run
outside the __builtin_cpu_supports() check, and meson
doesn't allow per-file cflags. So we have to split this
code off into its own static library.
When building for homebrew/linuxbrew on Ubuntu 16.04, memfd_create() is
not available and causes the build to fail.
This adds a proper check for the function.
The gtk_debug_cflags variable is an array, with each argument stored in
a separate string; if we add multiple arguments inside the same string
we break the escaping rules.
Fixes: #3864
It is also possible to enable F16C instructions on 32-bit Visual Studio builds,
so also check for the compiler's ability to build F16C code on Visual Studio
32-bit instead of just bailing out.
The __builtin_cpu...() intrisics are strictly for GCC/CLang-based compilers, so
don't use them in the checking code on Visual Studio. The test code will still
compile without this change, but will certainly fail if we want it to link.
Use an IFUNC resolver to determine whether we can use
intrinsics for FP16 conversion. This requires the functions
to be no longer inline.
Sadly, it turns out that __builtin_cpu_supports ("f16c")
doesn't compile on the systems where we want it to prevent
us from getting a SIGILL at runtime.
