Currently meson only considers what compiler/linker were used by a
Target's immediate sources or objects, not the sources of libraries it's
linked with by the link_with and link_while keywords. This means that if
given 3 libraries: libA which is C++, libB which is C, and libC which is
also C, and libC links with libB which links with libA then linking libC
will be attempted with the C linker, and will fail.
This patch corrects that by adding the compilers used by sub libraries
to the collection of compilers considered by meson when picking a
linker.
This adds a new process_compilers_late method to the BuildTarget class,
which is evaluated after process_kwargs is called. This is needed
because some D options need to be evaluated after compilers are
selected, while for C-like languages we need to check the link* targets
for language requirements, and link* targets are passed by kwargs.
This implementation is recursive, since each Target adds it's parent's
dependencies.
Add new 'docbook' argument which generates Docbook documentation for
each D-Bus interface. The docbook argument will be used as prefix
in `PREFIX`-NAME.xml pattern, and NAME will be replaced by the D-Bus
interfaces.
Adding it to the end of PATH means that if an installed instance of a DLL
exists, that would be used instead of the built instance.
Compare with run_exe(), which already gets this right.
Of course D compilers have different flags to set some important
D-specific settings. This adds a simple method to change these flags in
a compiler-agnostic way in Meson.
This replaces the previous `unittest_args` method with a more generic
variant.
Otherwise we might end up with wrapper holders in the Build object and
pickling will then fail, defeating the purpose of the holder objects.
Closes https://github.com/mesonbuild/meson/issues/2211
Custom target include dirs must be overridable by target-specific
include dirs otherwise in case of header name collisions, the user has
no way to override this behaviour.
If we don't do that, the traversal of the sources list to generate the
sources file for g-ir-scanner is going to explode with a Python
backtrace like this one:
File "/usr/lib/python3.5/site-packages/mesonbuild/modules/gnome.py", line 463, in generate_gir
gir_filelist.write(os.path.join(srcdir, s) + '\n')
File "/usr/lib/python3.5/posixpath.py", line 89, in join
genericpath._check_arg_types('join', a, *p)
File "/usr/lib/python3.5/genericpath.py", line 143, in _check_arg_types
(funcname, s.__class__.__name__)) from None
if the sources list contains a list.
An example trace:
[snip]
> File "/usr/lib/python3.6/concurrent/futures/thread.py", line 55, in run
> result = self.fn(*self.args, **self.kwargs)
> File "/home/trhd/Projects/meson/mesonbuild/mtest.py", line 221, in run_single_test
> child_env.update(self.options.global_env.get_env(child_env))
> AttributeError: 'dict' object has no attribute 'get_env'
On Windows, one will face the issue of the 8192-character limit for each
command line, so this will cause an issue when one is building items
like GTK+ with introspection, because the g-ir-scanner command line will
likely get too long, which will clearly break the build. This will
affect all Windows builds.
Make use of the --filelist option that is already in g-ir-scanner, and
generate such a file list from the sources that are fed to
generate_gir(), named as
$(builddir)/$(target_id)/<NameSpace>_<NameSpaceVersion>_gir_filelist
and using it during the build.
* add support for cups dependencies
libcups has its own cups-config tool rather than using pkg-config.
This adds support for cups-config, based on pcap-config and
sdl2-config implementations.
This change also includes the unit test case and documentation for
cups dependency object implementation, and libcups2 dep to CI image.
