everything else.

Suggest seting flake8 as a pre-commit hook
Those tools use our arguments to build a file and execute it to
introspect it at runtime. However, they do not know that you can pass
the full path to the library to use, and ignore the arguments.
The long-term fix for this is to have them output a .c file that Meson
will build for them, which they can then run, but that will require
upstream changes:
https://gitlab.gnome.org/GNOME/gtk-doc/merge_requests/1
Closes https://github.com/mesonbuild/meson/issues/3774
When an older version of the library being built is installed in the
same prefix as external dependencies, we have to be careful to construct
the linker or compiler command line. If a -L flag from external
dependencoes comes before a -L flag pointing to builddir, it is possible
for the linker to load older libraries from the installation prefix
instead of the newly built ones, which is likely to cause undefined
reference error.
Since the order of dependencies is not significant, we cannot expect
internal dependencies to appear before external dependencies when
recursively iterating the list of dependencies. To make it harder to
make mistakes, linker flags come from internal and external
dependencies are now stored in different order sets. Code using
_get_dependencies_flags are expected to follow the order when
constructing linker command line:
1. Internal linker flags
2. LDFLAGS set by users
3. External linker flags
It is similar to what automake and libtool do for autotools projects.
In GLib when running "ninja gio-doc" without doing a full build first,
it won't build libraries and the generated gio-scan.c gets linked
against system libgio instead.
This fix 2 bugs: gtkdoc() was not passing 'depends' variable down to
_get_dependencies_flags(), and many places had 'if depends' which is
False when 'depends' is an empty list and not only when it's None. There
is no reason for that argument to be optional, we always want to collect
dependencies.
We were setting it to a file list that would always be wrong, and
always out of date since it would never exist.
However, the output list is not predictable. It usually has a 1-1
relationship with the input XML files, but it may not.
This must be fixed later with API for users to provide the output
names.
See: https://github.com/mesonbuild/meson/pull/3539
If we pass a source files() object, we will look for it in the build
directory, which is wrong. If we pass a build files() object (from
configure_file()), we will find it in the build directory, and then
try to copy it on top of itself in gtkdochelper.py getting a
SameFileError.
Add a test for it, and also properly iterate custom target outputs
when adding to content files.
The fix has landed upstream, and will be in the next glib stable
release. I have verified that it fixes the problem described in #3488
and that the 'frameworks/7 gnome' test passes now.
The new --body and --header args are broken because they do not allow
the use of --output-directory to set the correct `#include "foo.h"`
line in `foo.c`. The changes in the gdbus test case show this.
Disabled till this can be fixed in glib.
Closes https://github.com/mesonbuild/meson/issues/3488
* gnome: If pkg-config is not found, assume glib is 2.0
Checking the pkg-config file to confirm tool versions is a hack, and
should eventually be replaced with checking the actual versions of the
tools.
* gnome: Actually assume glib version is 2.54 if not found
It is actually not possible to build most projects with the GNOME
module if your glib is older, particularly genmarshal and
gdbus-codegen generate unusable output without newer arguments that
were added for Meson.
The `install` parameter that is present in the `permittedKwargs`
annotation is wrong. The correct parameter name, which is also
consistent with the rest of functions in the `gnome` module, is
`install_dir`.
The `ct` variable used in the ModuleReturnValue is created only for
versions earlier than 2.55.2. However, in newer versions that
variable does not exist.
The development version of `glib` (2.55.2) has acquired support for
generating gdbus header and source code files separately. This
allows dependencies to be more fine grained on those targets
depending only on the header.
* Never install the glib-mkenums generated C source
When using gnome.mkenums_simple() we end up installing the generated
C source file alongside the C header file, if `install_header` is set
to True. This is caused by mkenums_simple() acting as a wrapper for
mkenums() without template files; mkenums() won't be able to know if
we're generating the header or the source, and will use the presence
of `install_header` as the deciding factor as to whether the generated
file should be installed.
When generating the C source file, we should always unset the
`install_header` option to False, just like mkenums() expects.
Closes#3373
* Verify that mkenums_simple() does not install C sources
When asked to installed the generated C header file.
The reason for this change is the same as the previous commit. Although
g-ir-scanner can pick arguments from CFLAGS, CPPFLAGS, LDFLAGS
environment variables by itself, it is still better for build systems
to put them on the command line instead of relying on users to setup
the same environment.
Since g-ir-scanner doesn't provide a way to set arbitrary linker flags
on the command line, arguments in LDFLAGS that are not started with -L
are not passed.
