We now need glib-2.76.0 or later, which removes our needs for the workarounds
that we need to build the media backends against GLib-2.74.x or earlier, so
clean up things a bit.
We are now using APIs that were introduced in 2.75.x, so let's use glib-2.76.0
here for our glib subproject.
Update the build and gobject-introspection items accordingly
Instead of injecting `-fvisibility=hidden` depending on a compiler check
ourselves, let Meson do it for us.
This also avoids us having to filter `-fvisibility=hidden` when reusing
the common compiler flags.
Fix the circular dependency by moving the generated
headers to gdk/version/, and build that directory
first.
Misc other fixes, such as putting the custom targets
as sources, not depedencies, and using the correct
major version in the generator script.
Let's poach the same script used by GLib to avoid having to add all the
version macros by hand every time we increment the GTK version.
This is a work in progress:
- need to rename the GLIB_STATIC_COMPILATION check
- circular dependency: libgtkcss depends on gdkversionmacros.h, but libgdk
depends on libgtkcss
Error out if introspection is requested,
but g-ir-scanner isn't found.
And if introspection isn't explicitly disabled
but is required for building the docs, build it.
The current definitions of the g_io_module_*() symbols do not build on
Visual Studio when building against GLib earlier than 2.75.0 due to the
way how these symbols are decorated in the GLib headers, as Visual Studio
does not allow symbols that were previously marked with 'extern' (or so)
to be marked with anything that is symantically different later.
As a result, if we are using Visual Studio and glib-2.74.x or earlier,
override _GLIB_EXTERN as appropriate in the modules/media sources before
including the GIO headers. This sadly, means that we need a
configure-time check as it would have been too late if we checked the
GLib version using G_VERSION_CHECK macro, as the GIO headers would have
been included already.
There are similar items in the print backends, but we will not attempt
to update these files as they are not meant to be built for Windows.
Put all the function checks in one place.
Remove functions we don't actually use,
and add ones that we have #ifdefs for in
in the code. Also add enough includes to
make these checks actually work.
Fixes: #5070
This issues a warning when an enum value is compared to a value that is
out of range for the enum.
We do this a lot, either when using -1 for undefined values or when
comparing array sizes to enum values like so:
enum {
ONE,
TWO,
THREE
} some_enum_value;
const char *names= { "one", "two", "three" };
g_assert (some_enum_value < G_N_ELEMENTS (names));
The way the check is written, if the build is native, then the
introspection option has no effect.
Particularly yocto project does want to disable introspection in
native builds and enable it in cross builds (both via the option),
and without this patch the former is not possible.

Dummy dependencies are not required to execute a subproject
automatically for providing a program, nor do you need to explicitly
call subproject() to do that.
A `[provide]` section in the wrap file is enough.
Subprojects that use meson.override_dependency() do not require the
caller to provide the dependency variable name inside the subproject.
We also don't want to provide the *subproject* name, because the
subproject name can be `pango-1.50.12` instead of `pango` when using
wrap-file to download the tarball instead of using wrap-git. This
causes the pango subproject to be executed twice when using gtk as
a subproject inside gstreamer (which uses pango-1.50.12 as
a wrap-file).
All the dependencies we use can be switched in this way, but the
remaining ones need to be changed to use meson.override_dependency()
first.
The is_msvc_like change is wrong; it used a false correlation between
"compiler being used" and "dependency method" by saying that on
Windows, when building with MSVC, you will only use CMake to find png,
jpeg, tiff.
You can use pkgconfig to find these deps on Windows with MSVC -- when
the deps have been built with Autotools or Meson (with MSVC). You can
also find these deps using CMake on other platforms like macOS or
Linux.
The solution is simple: just search for both names on all platforms,
and just search for the pkgconfig name first.
This reverts commit acd9c12667.
This commit breaks the build with GLib main on all platforms,
and defining _GLIB_EXTERN arguably invades the GLib namespace.
A different fix for msvc will have to be found.
This is an experiment to see if I can keep up with
doing post-release version bumps, so git snapshots
will always have a different version from released
tarballs.
This commit also marks the beginning of the 4.10
development cycle, as 4.8 has been branched.
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.
