This error message was quite confusing when triggered by
use of an absolute path to the include dir of an external dependency
(numpy in my case). Changing that to a relative dir also isn't
a solution, because Meson will *not* do the "busywork to make paths
work" that the error message says it will.
We have to handle this, because Windows needs to link to the implib of
the executable (???) in order to create a shared module. This is
explicitly checked for and handled in the backend, and creating a build
target with `link_with: some_exe` still works, even. But updating
declare_dependency to typed_kwargs neglected to take that into account,
so creating a convenience interface for those same arguments failed.
We can use this lots of places, and it's always the same kwarg. There
doesn't seem to be a point in naming it badly, then evolving it to the
standard name in the one place it is currently used. This made it not
shareable.
The check for whether or not a file is allowed to be accessed from a
subproject fails if the subproject is accessed via a symlink. Use the
absolute path of the subproject without resolving symlinks to fix the
check.
Extend unit test 106 to check for this in the future.
At several points in the code base, f-strings are not correctly expanded
due to missing 'f' string prefix. This fixes all the occurrences I could
find.
When a subproject is disabled on the initial configuration we should not
add it into self.coredata.initialized_subprojects because that will
prevent calling self.coredata.init_builtins() on a reconfigure if the
subproject gets enabled.
Fixes: #10225.
Fix "Tried to grab file outside current (sub)project" error when subproject exists within
a source tree but it is used through a symlink. Using subprojects as symlinks is very useful
feature when migrating an existing codebase to meson that all sources do not need to be
immediately moved to subprojects folder.
CT_OUTPUT_KW is the same OUTPUT_KW we use in lots of places. The most
distinctive thing about it is not that it's part of custom_target
(basically any other function that uses such a kwarg follows the same
rules due to using CustomTarget under the hood), but the fact that it
takes multiple outputs.
We validate a few things here, such as the non-presence of '@INPUT' in
an output name. These got moved out of the CustomTarget constructor in
commit 11f9638035 and into KwargInfo, but
only for kwargs that took multiple values. This caused configure_file()
and unstable_rust.bindgen() to stop checking for this.
Add a shared single-output KW and use it in both places. This now
dispatches to _output_validator.
configure_file now validates subdirectories in output names the same way
we do elsewhere, directly in the typed_kwargs and by specifying the
erroring kwarg.
Or any other reserved names. We check in add_target that the primary
name of any build target isn't on the forbidden list, but custom_target
allows names that are distinct from the output filenames, so we need to
check those too.
We would eventually still error out all the way at the end, with:
```
ERROR: Multiple producers for Ninja target "all". Please rename your targets.
```
But, if we can check that early and provide the underlying reason
(reserved name) alongside actually useful debugging info (a line
number), then why not?
Refactor the check into a small helper function in the process.
We don't want to allow targets that conflict with:
- our aliased meson-* targets for phony commands
- any meson-*/ directories we create for internal purposes
We do want to allow targets such as:
- our own meson-*.X manpages
There are a couple routes we could take.
Using a better restriction, such as `meson-internal__*`, is trivially
done for our aliased targets, but changing directory names is...
awkward. We probably cannot do this, and doing the former but not the
latter is not very useful.
We could also carefully allow patterns we know we won't use, such as
file extensions, but which the manpages need, which works for our
directories and for many aliased targets, but run_target() is
user-specified and can be anything.
Use a hybrid approach to cover both use cases. We will now allow target
names that fulfill *all* the following criteria:
- it begins with "meson-"
- it doesn't continue with "internal__"
- it has a file extension
The `install_headers` function now has an optional argument
`preserve_path` that allows installing multi-directory
headerfile structures that live alongside sourcecode with a
single command.
For example, the headerfile structure
headers = [
'one.h',
'two.h',
'alpha/one.h',
'alpha/two.h',
'alpha/three.h'
'beta/one.h'
]
can now be passed to `install_headers(headers, subdir: 'mylib', preserve_path: true)`
and the resulting directory tree will look like
{prefix}
└── include
└── mylib
├── alpha
│ ├── one.h
│ ├── two.h
│ └── three.h
├── beta
│ └── one.h
├── one.h
└── two.h
Fixes#3371
We have two checks for the type accepted here. One is the basic
typed_kwargs type-checking, which declares it accepts:
str | include_directories
The other is the custom validator which further narrows it to strings
with certain option-like properties (needs to be an = assignment).
The former is obviously wrong, which doesn't really matter all that much
but still isn't very nice...
Introduced in commit f34013fb08.
override_options makes no sense for custom_target as we don't use it for
anything. Also, this was added in commit c3c30d4b06
despite not being allowed in permittedKwargsc3c30d4b0.
For inexplicable reasons, we had a known_kwargs for custom_target that
looped over kwargs and issued a warning, not an error, for unknown
kwargs. It was impossible to ever hit that check to begin with, though,
ever since commit e08d735105 which added
permittedKwargs and obsoleted those manual checks with real errors.
So at one point override_options was specially permitted to be used
without emitting a warning, and then for about half a decade it was an
error, and then based on some dead code it was allowed again for a bit.
But through all this it doesn't do anything and isn't documented.
We accept boolean false to indicate "do not install this one particular
output", but the type checking simply checked if it is a bool. We do
this correctly for configure_file, so copy the same validator from
there.
This fixes bogus messages "skipped: feature foo disabled" when
auto_features=disabled. It was reporting the name of the latest
get_option() call instead of the name of the current feature option.
This is especially visible in GStreamer summary where it should show a
different option name for every subproject but instead shows "tools"
everywhere:
```
Subprojects
gst-devtools : NO Feature 'tools' disabled
gst-editing-services : NO Feature 'tools' disabled
...
```
Change message
Header <foo.h> has symbol "BAR"
to
Header "foo.h" has symbol "BAR"
with the first part also now in bold. This is more consistent with
other messages like
Has header "foo.h"
and
Checking whether type "foo" has member "bar"
We were poking directly at the node, so if it was a FunctionNode then
this broke. Instead, just do a reverse lookup in the overrides table to
get the original find_program name.
In commit 6acfe48f32, the kwarg was added
to environment() in addition to the env object methods. As part of the
associated refactor, a shared KwargInfo was used, and evolved to be new
since 0.62.0 in the two cases where it is in fact new.
However, it *also* set the base KwargInfo for the exact same newness,
which is wrong as it was present ever since the initial introduction in
0.34.0
As usual for anything that predates 0.37.0 we simply don't tag
FeatureNew. Revert this back to the same KwargInfo definition from
before the refactoring commit.
Fixes#10402
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.
Some projects treat meson.project_source_root() as the root of the
dependency files, because the project itself merely wraps a bunch of
datafiles. Our validation to make sure this doesn't point to another
subproject, made use of pathlib.Path's generator for all component
paths, which... did not include the path itself. So go ahead and
explicitly check that too. Add a test case to verify it while we are at
it.

This function can be used to add fundamental dependencies such as glib
to all build products in one fell swoop. This can be useful whenever,
due to a project's coding conventions, it is not really possible to
compile any source file without including the dependency.

This handles various edge cases:
- checks for sandbox violations just like all other functions
- warn for direntry issues
- check for generated files referred to via strings instead of the
returned object
(All valid use cases for wanting to sneak around the checks, are made to
work via commit bba588d8b03a9125bf5c4faaad31b70d39242b68.)
This allows tracking which subproject it came from at the time of
definition, rather than the time of use. As a result, it is no longer
possible for one subproject which knows that another subproject installs
some data files, to expose those data files via its own
declare_dependency.
There are somewhat common, reasonable and legitimate use cases for a
dependency to provide data files installed to /usr which are used as
command inputs. When getting a dependency from a subproject, however,
the attempt to directly construct an input file from a subproject
results in a sandbox violation. This means not all dependencies can be
wrapped as a subproject.
One example is wayland-protocols XML files which get scanned and used to
produce C source files.
Teach Meson to recognize when a string path is the result of fetching a
dep.get_variable(), and special case this to be exempt from subproject
violations.
A requirement of this is that the file must be installed by
install_data() or install_subdir() because otherwise it is not actually
representative of what a pkg-config dependency would provide.
dep.get_variable() only supports string values for pkg-config and
config-tool, because those interfaces use text communication, and
internal variables (from declare_dependency) operate the same way.
CMake had an oddity, where get_variable doesn't document that it allows
list values but apparently it miiiiiight work? Actually getting that
kind of result would be dangerously inconsistent though. Also, CMake
does not support lists so it's a lie. Strings that are *treated* as
lists with `;` splitting don't count...
We could do two things here:
- raise an error
- treat it as a string and return a string
It's not clear what the use case of get_variable() on a maybe-list is,
and should probably be a hard error. But that's controversial, so
instead we just return the original `;`-delimited string. It is probably
the wrong thing, but users are welcome to cope with that somehow on
their own.
This moves generally useful logic from GNOME module's
_get_native_binary() into find_program() implementation. We could decide
later to expose it as public API.
Adds a new debug() function that can be used in the meson.build to
log messages to the meson-log.txt that will not be printed to stdout
when configuring the project.
These are only used for type checking, so don't bother importing them at
runtime.
Generally add future annotations at the same time, to make sure that
existing uses of these imports don't need to be quoted.
