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.
Currently default_options uses "" for the kwarks id, however this
is incorect and it must be "/". Additionally, this error won't be
ignored in the future with "--skip" (this is why the tests were
passing and this wasn't detected earlier).
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 8377ea45aa
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.
Apparently we have no tests for this because this is broken pretty
badly. This extends the basic test to actually check for the correct
free-form argument and thus test this.
This test currently assumes that the fortran compiler is gfotran, and
if we're not using g++ it skips. This patch changes it to skip if the
fotran compiler and the c++ compiler aren't the same family. This still
may skip in some cases it shouldn't (clang and gfort probably work fine
on windows), but it does enable ifort + ICL. Which is hte point.
