Functional behaviour is not identical, because the cache not set
when an exception is thrown. I hope this doesn't matter in practice.
|
|
|
|
The helper is general, although in this patch it is only used for
warnings. No functional change intended.
|

The main library must come before extra libraries, because they are
likely to be dependencies of the main library that get promoted from
private to public. This was causing static link issues with glib-2.0.pc.

If the Python binary that we find doesn't return valid JSON when asked to run a
small script, show the command being ran and stdout/stderr in meson-log.txt.
Fixes: #5914

When g-ir-scanner is overriden, we can't call it at configure time
but we know what options are avalaible (as it started using meson
after checked options where added) so do not try to call it to retrieve
the version as it will fail.

GLib does not currently use override_find_program() for this tool
because it is compiled and would not work in cross build. But this
prepares Meson for when/if GLib will rewrite it in Python.
See https://gitlab.gnome.org/GNOME/glib/issues/1859.

'if_true' sources should be built with their dependencies, as
illustrated by test case change.
Ideally, I think we would want only the files with the dependencies to
be built with the flags, but that would probably change the way
sourceset are used.

The feature check facilities need to have access to subproject.
|
|
This will allow using gtk-doc as a subproject instead of having to
install it on the system. It also has the side effect of failing at
configuration time with a proper message if gtkdoc is not installed,
instead of failing at build time with a python backtrace.
|
|
At configure time, kconfig can read from configure_file().
"test cases/kconfig/4 load_config builddir/meson.build" was already
showing a workaround, now it actually can take configure_file input
directly.
|
|
This simplifies and cleans things up.

* gtkdoc: Add 'check' kwarg
This runs gtkdoc-check in meson tests.
Also reorganize the gtkdoc test because we cannot reliably build
multiple doc into the same directory. Not all files generated by gtk-doc
are prefixed with the target name.

This mirrors the modules keyword argument that some dependencies (such
as qt and llvm) take. This allows an easier method to determine if
modules are installed.
|
|
In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.

determine_rpath_dirs() can return paths to external dependencies not
in the build dir and passing them first as a link path leads to
g-ir-scanner for example linking against the already installed library
instead of the just built one.
This was reported in g-i: https://gitlab.gnome.org/GNOME/gobject-introspection/issues/272
and comes up quite often when a library adds some new symbols which aren't present in the
system library, which then makes linking fail.
The first place where the order is changed is _scan_gir_targets(), which looks like an unintentional
change in the refactoring in 8377ea45aa61efbe8e1a75b74
The second place in _get_link_args() has always been that way and only the rpath order is changed,
but it looks to me as if the same rules should apply here too.

In QEMU a single set of source files is built against many different
configurations in order to generate many executable. Each executable
includes a different but overlapping subset of the source files; some
of the files are compiled separately for each output, others are
compiled just once.
Using Makefiles, this is achieved with a complicated mechanism involving
a combination of non-recursive and recursive make; Meson can do better,
but because there are hundreds of such conditional rules, it's important
to keep meson.build files brief and easy to follow. Therefore, this
commit adds a new module to satisfy this use case while preserving
Meson's declarative nature.
Configurations are mapped to a configuration_data object, and a new
"source set" object is used to store all the rules, and then retrieve
the desired set of sources together with their dependencies.
The test case shows how extract_objects can be used to satisfy both
cases, i.e. when the object files are shared across targets and when
they have to be separate. In the real-world case, a project would use
two source set objects for the two cases and then do
"executable(..., sources: ... , objects: ...)". The next commit
adds such an example.

We are emitting a static string, so use that shortcut function to
intern it, which will save one allocation.

coredata: add pkg_config_path to depedency cache key
|
|
It doesn't make much sense to have this and not also have
cross-compilers (so any use of this is already pretty suspect as
probably wrong when cross-compiling).
This information is accessible anyhow via environment.coredata.
|
|
|
|
Using a set breaks certain flags like `--param'.

I ran the numbers once before (it's in the meson history) but it's
*much* faster to *not* use len for testing if a container is empty or
not.

Instead of printing a message about how python was skipped, print the
normal 'Program foo found:' message, with a "disabled by feature"
message added.
|
|
This will help developers not introduce bugs (say putting 3 instead of
"python3"), and will be useful for the next patch.

Currently find_installation is silent, which is pretty annoying. Let's
log it.
