- Update to version 0.50.0
New features:
* Added `cmake_module_path` and `cmake_args` to dependency
The CMake dependency backend can now make use of existing
`Find<name>.cmake` files by setting the `CMAKE_MODULE_PATH`
with the new `dependency()` property `cmake_module_path`.
The paths given to `cmake_module_path` should be relative
to the project source directory.
Furthermore the property `cmake_args` was added to give
CMake additional parameters.
* Added PGI compiler support
Nvidia / PGI C, C++ and Fortran
[no-cost](https://www.pgroup.com/products/community.htm)
compilers are now supported. They have been tested on Linux
so far.
* Fortran Coarray
Fortran 2008 / 2018 coarray support was added via
`dependency('coarray')`
* Libdir defaults to `lib` when cross compiling
Previously `libdir` defaulted to the value of the build
machine such as `lib/x86_64-linux-gnu`, which is almost
always incorrect when cross compiling. It now defaults to
plain `lib` when cross compiling. Native builds remain
unchanged and will point to the current system's library
dir.
* Native and Cross File Paths and Directories
A new `[paths]` section has been added to native and cross
files. This can be used to set paths such a prefix and
libdir in a persistent way.
* Add warning_level 0 option
Adds support for a warning level 0 which does not enable any
static analysis checks from the compiler
* A builtin target to run clang-format
If you have `clang-format` installed and there is a
`.clang-format` file in the root of your master project,
Meson will generate a run target called `clang-format` so you
can reformat all files with one command:
```meson
ninja clang-format
```
* Added a .path() method to object return by
python.find_installation()
`ExternalProgram` objects as well as the object returned by
the `python3` module provide this method, but the new python
module did not.
* Fix ninja console log from generators with multiple output
nodes
This resolves ticket #4760 where a generator w/ multiple
output nodes printed an empty string to the console
* `introspect --buildoptions` can now be used without
configured build directory
It is now possible to run `meson introspect --buildoptions
/path/to/meson.build` without a configured build directory.
Running `--buildoptions` without a build directory produces
the same output as running it with a freshly configured
build directory.
However, this behavior is not guaranteed if subprojects are
present. Due to internal limitations all subprojects are
processed even if they are never used in a real meson run.
Because of this options for the subprojects can differ.
* `include_directories` accepts a string
The `include_directories` keyword argument now accepts plain
strings rather than an include directory object. Meson will
transparently expand it so that a declaration like this:
```meson
executable(..., include_directories: 'foo')
```
Is equivalent to this:
```meson
foo_inc = include_directories('foo')
executable(..., include_directories: inc)
```
* Fortran submodule support
Initial support for Fortran ``submodule`` was added, where
the submodule is in the same or different file than the
parent ``module``.
The submodule hierarchy specified in the source Fortran code
`submodule` statements are used by Meson to resolve source
file dependencies.
For example:
```fortran
submodule (ancestor:parent) child
```
* Add subproject_dir to --projectinfo introspection output
This allows applications interfacing with Meson (such as
IDEs) to know about an overridden subproject directory.
* Find library with its headers
The `find_library()` method can now also verify if the
library's headers are found in a single call, using the
`has_header()` method internally.
```meson
+ Aborts if the 'z' library is found but not its header file
zlib = find_library('z', has_headers : 'zlib.h')
+ Returns not-found if the 'z' library is found but not its
header file zlib = find_library('z', has_headers :
'zlib.h', required : false)
```
Any keyword argument with the `header_` prefix passed to
`find_library()` will be passed to the `has_header()`
method with the prefix removed.
```meson
libfoo = find_library('foo',
has_headers : ['foo.h', 'bar.h'],
header_prefix : '#include <baz.h>',
header_include_directories : include_directories('.'))
```
* NetCDF
NetCDF support for C, C++ and Fortran is added via
pkg-config.
* added the Flang compiler
[Flang](https://github.com/flang-compiler/flang/releases)
Fortran compiler support was added. As with other Fortran
compilers, flang is specified using `FC=flang meson ..` or
similar.
* New `not_found_message` for dependency
You can now specify a `not_found_message` that will be
printed if the specified dependency was not found. The point
is to convert constructs
that look like this:
```meson
d = dependency('something', required: false)
if not d.found()
message('Will not be able to do something.')
endif
```
Into this:
```meson
d = dependency('something',
required: false,
not_found_message: 'Will not be able to do something.')
```
Or constructs like this:
```meson
d = dependency('something', required: false)
if not d.found()
error('Install something by doing XYZ.')
endif
```
into this:
```meson
d = dependency('something',
not_found_message: 'Install something by doing XYZ.')
```
Which works, because the default value of `required` is
`true`.
* Cuda support
Compiling Cuda source code is now supported, though only
with the
Ninja backend. This has been tested only on Linux for now.
Because NVidia's Cuda compiler does not produce `.d`
dependency files, dependency tracking does not work.
* `run_command` accepts `env` kwarg
You can pass
[`environment`](Reference-manual.html#environment-object)
object to
[`run_command`](Reference-manual.html#run-command), just
like to `test`:
```meson
env = environment()
env.set('FOO', 'bar')
run_command('command', 'arg1', 'arg2', env: env)
```
* `extract_objects` accepts `File` arguments
The `extract_objects` function now supports File objects to
tell it what to extract. Previously, file paths could only
be passed as strings.
* Changed the JSON format of the introspection
All paths used in the meson introspection JSON format are
now absolute. This affects the `filename` key in the targets
introspection and the output of
`--buildsystem-files`.
Furthermore, the `filename` and `install_filename` keys in
the targets introspection are now lists of strings with
identical length.
The `--target-files` option is now deprecated, since the
same information can be acquired from the `--tragets`
introspection API.
* Meson file rewriter
This release adds the functionality to perform some basic
modification on the `meson.build` files from the command
line. The currently supported operations are:
+ For build targets:
x Add/Remove source files
x Add/Remove targets
x- Modify a select set of kwargs
x Print some JSON information
+ For dependencies:
x Modify a select set of kwargs
+ For the project function:
x Modify a select set of kwargs
x Modify the default options list
For more information see the rewriter documentation.
* `introspect --scan-dependencies` can now be used to scan for
dependencies used in a project
It is now possible to run `meson introspect
--scan-dependencies
/path/to/meson.build` without a configured build directory
to scan for dependencies.
The output format is as follows:
```json
[
{
"name": "The name of the dependency",
"required": true,
"conditional": false,
"has_fallback": false
}
]
```
The `required` keyword specifies whether the dependency is
marked as required in the `meson.build` (all dependencies are
required by default). The `conditional` key indicates whether
the `dependency()` function was called inside a conditional
block. In a real meson run these dependencies might not be
used, thus they _may_ not be required, even if the
`required` key is set. The `has_fallback` key just indicates
whether a fallback was directly set in the `dependency()`
function.
* `introspect --targets` can now be used without configured
build directory
It is now possible to run `meson introspect --targets
/path/to/meson.build` without a configured build directory.
The generated output is similar to running the introspection
with a build directory. However, there are some key
differences:
+ The paths in `filename` now are _relative_ to the future
build directory
+ The `install_filename` key is completely missing
+ There is only one entry in `target_sources`:
x With the language set to `unknown`
x Empty lists for `compiler` and `parameters` and
`generated_sources`
x The `sources` list _should_ contain all sources of the
target
There is no guarantee that the sources list in
`target_sources` is correct.
There might be differences, due to internal limitations. It
is also not guaranteed that all targets will be listed in
the output. It might even be possible that targets are
listed, which won't exist when meson is run normally.
This can happen if a target is defined inside an if
statement.
Use this feature with care.
* Added option to introspect multiple parameters at once
Meson introspect can now print the results of multiple
introspection commands in a single call. The results are
then printed as a single JSON object.
The format for a single command was not changed to keep
backward compatibility.
Furthermore the option `-a,--all`, `-i,--indent` and
`-f,--force-object-output` were added to print all
introspection information in one go,
format the JSON output (the default is still compact JSON)
and force use the new output format, even if only one
introspection command was given.
A complete introspection dump is also stored in the
`meson-info` directory. This dump will be (re)generated each
time meson updates the configuration of the build directory.
Additionlly the format of `meson introspect target` was
changed:
+ New: the `sources` key. It stores the source files of a
target and their compiler parameters.
+ New: the `defined_in` key. It stores the meson file
where a target is defined
+ New: the `subproject` key. It stores the name of the
subproject where a target is defined.
+ Added new target types (`jar`, `shared module`).
* meson configure can now print the default options of an
unconfigured project
With this release, it is also possible to get a list of all
build options by invoking `meson configure` with the project
source directory or the path to the root `meson.build`. In
this case, meson will print the default values of all
options.
* HDF5
HDF5 support is added via pkg-config.
* Added the `meson-info.json` introspection file
Meson now generates a `meson-info.json` file in the
`meson-info` directory to provide introspection information
about the latest meson run. This file is updated when the
build configuration is changed and the build files are
(re)generated.
