When we create a dependency as part of another dependency (say Threads),
we want to pass down most of the methods (like required). Currently
however, there is the possibility that we can pass down invalid keyword
arguments, such as 'method'. This new method is meant to work around
that my simplifying and centralizing how we pass these dependencies
down.
Some things, like `method[...](...)` or `x: ... = ...` python 3.5
doesn't support, so I made a comment instead with the intention that it
can someday be made into a real annotation.
Instad of having special casing of threads in the backends and
everywehre else, do what we did for openmp, create a real
dependency. Then make use of the fact that dependencies can now have
sub dependencies to add threads.
I'll be using this later, but it seems useful to allow dependencies to
that have special handlers to declare that they depend on other
dependencies. This should allow us to stop treating threads special
internally and just make it a normal dependency.
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
Currently InternalDependency.get_partial_dependency shadows the the
input variables names, and then passes those new copies to the final
object returned. It also passes them to the arguments of of
get_partial_dependency for each subdependency, which is wrong. The
code is supposed to proxy the original argumetn values to that instead
of the shadowing values.
To avoid that this patch renames the new values.
It was a mistake in retrospect to not make this deprecated in the
first place, so let's do that. When cross files were new we needed
this as a way to specify a llvm-config binary, since it could be
passed via PATH overrides.
Whenever a non-executable Python script is found by find_program, currently
Haiku and Windows replace a python3 from the shebang line with the one that
was used by Meson. Extend this behavior to POSIX systems so that it is
easy to test a program with multiple Python versions.
Currently this is particularly important for generators, because
they don't allow files in the arguments and thus you cannot do
something like
g = generator(pymod.find_installation(), ...,
arguments: [files('myscript.py'), ...])
With this patch, instead, you can just do
g = generator(find_program('myscript.py'), ...)
This patch creates an enum for selecting libtype as static, shared,
prefer-static, or prefer-shared. This also renames 'static-shared'
with 'prefer_static' and 'shared-static' with 'prefer_shared'. This is
just a refactor with no behavioral changes or user facing changes.
Currently we specialcase OpenMP like we do threads, with a special
`need_openmp` method. This seems like a great idea, but doesn't work
out in practice, as well as it complicates the opemp
implementation. If GCC is built without opemp support for example, we
still add -fopenmp to the the command line, which results in
compilation errors.
This patch discards that and treats it like a normal dependency,
removes the need_openmp() method, and sets the compile_args attributes
from the compiler.
Fixes#5115
Fix 'not founded' message for packages with another name for
specific configurations instead of just 'library'.

Instead of only doing a naive filesystem search, also run the linker
so that it can tell us whether the -F path specified actually contains
the framework we're looking for.
Unfortunately, `extraframework` searching is still not 100% correct in
the case when since we want to search in either /Library/Frameworks or
in /System/Library/Frameworks but not in both. The -Z flag disables
searching in those prefixes and would in theory allow this, but then
you cannot force the linker to look in those by manually adding -F
args, so that doesn't work.
Also add a test for it. In the process, also remove an overly-zealous
try..except statement that was catching *all* exceptions, not just
expected ones, which was masking programming errors.
.get_command() will return None when it's not found, so there's no
point trying to print that. Print self.name instead, which is what
we tried to search for.
First, I noticed there was a dangling use of now-removed cross_info in
the CMake lookup. No tests had caught this, but it means that CMake deps
were totally broken. [It also meant that CMake could not be specified
from a native file.]
In a previous of mine PR which removed cross_info, I overhauled finding
pkg-config a bit so that the native and cross paths were shared. I
noticed that the CMake code greatly resembled the pkg-config code, so I
set about fixing it to match.
I then realized I could refactor things further, separating caching,
finding alternatives, and validating them, while also making the
validations less duplicated. So I ended up changing pkg config lookup a
lot too (and CMake again, to keep matching).
Overall, I think I have the proper ideom for tool lookup now, repated in
two places. I think it would make sense next to share this logic between
these two, compilers, static linkers, and any other tool similarly
specifiable. Either the `BinaryTable` class in environment.py, or a new
class for `Compiler` and friends to subclass, would be good candidates
for this.
In recent change, dependency('foo') does not return a not-found
PkgConfigDependency any more, but a NotFoundDependency object. This
creates a regression in gst-build that does
dependency('foo').get_partial_dependency() causing Meson to raise an
exception.
The returned not-found object can be from any type because we were
returning the first of the failed attempts. It also can happen that we
don't have any dependency object in which case we should just return
NotFoundDependency() object as well instead of raising an exception.
That exception was happening before, but dependency_impl() was
calling find_external_dependency() in a try block so it was hidden.
When req_version is None (e.g. pcap-config case) it gets printed in the
logs.
Take this opportunity to reformat the message to look more like
ExternalProgram messages.
