By default, meson will try to look for shared libraries first before
static ones. In the meson.build itself, one can use the static keyword
to control if a static library will be tried first but there's no simple
way for an end user performing a build to switch back and forth at will.
Let's cover this usecase by adding an option that allows a user to
specify if they want dependency lookups to try static or shared
libraries first. The writer of the meson.build can manually specify the
static keyword where appropriate which will override the value of this
option.
Extract to a separate function the code that resolves dependencies
for compiler methods. We will reuse it for add_project_dependencies().

JNI is a more apt name because it currently only supports the JNI. I
also believe that CMake uses the terminology JNI here as well.
JNI is currently the only way to interact with the JVM through native
code, but there is a project called "Project Panama" which aims to be
another way for native code to interact with the JVM.
On some platforms, this is provided by the base system, which
nevertheless refrains from providing the .pc files that go along with
it. As a result, it's impossible to sensibly find these dependencies.
I'm looking at you, FreeBSD...

This is also a problem on macOS, but that's unfixable (and I believe
they provide some truly ancient and out-of-support version anyway) and
you probably want to use the homebrew OpenSSL. Still, meson can now
detect these old versions and even set their version number.
Checking how to aquire the *gettext family of symbols portably is
annoyingly complex, and may come from the libc, or standalone.
builtin dependency:
This detects if libintl is unneeded, because the *gettext family of
symbols is available in the libc.
system dependency:
This detects if libintl is installed as separate software, linkable via
-lintl; unfortunately, GNU gettext does not ship pkg-config files for
it.

mesonbuild.dependencies.__init__ exposes configtool, pkgconfig, cmake
and more in __init__.py, so there's no reason we should be tying
SystemDependency to the internal organization implementation of the
subpackage!
In the 2nd previous commit it took quite some effort to figure out that
the python module "does not exist" because of import errors while
refactoring something completely different.
Currently the Qt Dependencies still use the old "combined" method for
dependencies with multiple ways to be found. This is problematic as it
means that `get_variable()` and friends don't work, as the dependency
can't implement any of those methods. The correct solution is to make
use of multiple Dependency instances, and a factory to tie them
together. This does that.
To handle QMake, I've leveraged the existing config-tool mechanism,
which allows us to save a good deal of code, and use well tested code
instead of rolling more of our own code.
The one thing this doesn't do, but we probably should, is expose the
macOS ExtraFrameworks directly, instead of forcing them to be found
through QMake. That is a problem for another series, and someone who
cares more about macOS than I do.
Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
This is a useful thing to document. I wasn't really sure where to put
it, but since it's developer oriented I figured in the code itself was
probably more useful and more likely to be seen than in the markdown
that generates the website.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
This makes use of proper ConfigTool and PkgConfig dependencies rather
than one big ExternalDependency that internally creates other
dependencies and then copies their attributes.
Basically this breaks down into three cases. An open source version with
compliant PkgConfig, valid CMake, and a Intel implementation that has
completely broken PkgConfig. For the first two cases we can use standard
classes, for the last we can make a subclass of PkgConfigDependency that
handles the special logic.
This doesn't change any of the logic, but it does re-organize it to be
clearer, and make use of the dependency factory API, which makes other
things (like Dependency.get_variable) work.
This is untested with Intel MKL.
This comes pre-installed, but currently we don't have a way to detect it
without relying on pkg-config or cmake. This is only valid with the
apple clang-based compilers, as they do some special magic to get
headers.
fixes#6096.
Didn't use CMake because Curses is a real corner-case for CMake that
would require Curses-specific enhancements to Meson's CMake interface.
Scalapack uses a library stack that can be challenging to manage.
Not least of all since many Scalapacks ship with broken / incomplete
pkg-config files and CMake FindScalapack.cmake
This resolves those issues for typical Scalapack setups including:
* Linux: Intel MKL or OpenMPI + Netlib
* MacOS: Intel MKL or OpenMPI + Netlib
* Windows: Intel MKL (OpenMPI not available on Windows)
This addresses various real-world problems with HDF5 pkg-config, including
* hdf*.pc with package versions as part of the filename
* malformed hdf*.pc missing the commonly-used HDF5 HL module
---
Additionally, this refactors more complicated dependencies such as
HDF5 and OpenMPI. This may help us deduplicate internal dependency
code in the future.
HDF5 selftest: improve platform-agnostic test
ci: init demo github action for HDF5 framework
ci Actions: hold off on MSYS2 for now [skip ci]
hdf5: ensure C libraries always included
ci: mac hdf5--use clang+gfortran
