Unlike Linux and OS X, when a library is loaded, all the symbols aren't
loaded into a single namespace. You must fetch the symbol by iterating over
all loaded modules.
So, we shouldn't use /FORCE:UNRESOLVED since that is not what modules do
on Windows. Instead, we now do exactly what GModule does on Windows.
Also use `void` for functions that take no arguments.
Using 'mesonbuild' as the module can cause it to use the
system-installed module and can also break if we rename the directory,
so avoid that by always using relative imports.
This is already how it should've been, but:
a) The test for this was wrong since Dependency is a base class for all
dependencies and isinstance on an InternalDependency will also be true
b) Internal dependencies can't ever be used here anyway because compiler
checks are always run at configure time and internal dependencies are
only built after that.
Also did a bit of cleanup.
interpreter.py: There’s a catch all except clause at the line 1928, it didn’t give the user any information whatsoever about the exception it caught. Now it at least print it to the log as a warning.
When generating the .gir file we need g-ir-scanner to link the
introspector binary against the right dependencies, for that
we used to use the --library option but this has a special meaning
and the libs passed in there end up being the ones in the .gir file
itself, which is not what we want.
A new --extra-library option is beeing added in goject-introspection
(https://bugzilla.gnome.org/show_bug.cgi?id=774625) to handle our use case
(ie. not using libtool which allows g-ir-scanner to know about those)
and we should make use of it.
Closes#981
Otherwise trying to introspect tests might lead to:

Sometimes we want to restrict the acceptable versions to a list of
versions, or a smallest-version + largest-version, or both. For
instance, GStreamer's opencv plugin is only compatible with
3.1.0 >= opencv >= 2.3.0
We want compiler check arguments (-O0, -fpermissive, etc) to override
all other arguments, and we want extra_args passed in by the build file
to always override everything.
To do this properly, we must split include arguments out, append them
first, append all other arguments as usual, and then append the rest.
As part of this, we also add the compiler check flags to the
cc.compiles() and cc.links() helper functions since they also most
likely need them.
Also includes a unit test for all this.
Many frameworks, such as glib, provide translation functions and
functions that take format strings. As such every application using
these must duplicate the gettext arguments to function properly.
This reduces that duplication and improves correctness so they are
not left out.
Fixes#1123
I hit an issue when building gtk-doc documentation. The issue is
my fault, but the error output from Meson makes it look like an
internal error:
[0/1] 'Running external command libtracker-sparql-doc.'
