|
||||
# New features |
||||
|
||||
## Bash completion scripts sourced in `meson devenv` |
||||
|
||||
If bash-completion scripts are being installed and the shell is bash, they will |
||||
be automatically sourced. |
||||
|
||||
## Setup GDB auto-load for `meson devenv` |
||||
|
||||
When GDB helper scripts (*-gdb.py, *-gdb.gdb, and *-gdb.csm) are installed with |
||||
a library name that matches one being built, Meson adds the needed auto-load |
||||
commands into `<builddir>/.gdbinit` file. When running gdb from top build |
||||
directory, that file is loaded by gdb automatically. |
||||
|
||||
## Print modified environment variables with `meson devenv --dump` |
||||
|
||||
With `--dump` option, all envorinment variables that have been modified are |
||||
printed instead of starting an interactive shell. It can be used by shell |
||||
scripts that wish to setup their environment themself. |
||||
|
||||
## New `method` and `separator` kwargs on `environment()` and `meson.add_devenv()` |
||||
|
||||
It simplifies this common pattern: |
||||
```meson |
||||
env = environment() |
||||
env.prepend('FOO', ['a', 'b'], separator: ',') |
||||
meson.add_devenv(env) |
||||
``` |
||||
|
||||
becomes one line: |
||||
```meson |
||||
meson.add_devenv({'FOO': ['a', 'b']}, method: 'prepend', separator: ',') |
||||
``` |
||||
|
||||
or two lines: |
||||
```meson |
||||
env = environment({'FOO': ['a', 'b']}, method: 'prepend', separator: ',') |
||||
meson.add_devenv(env) |
||||
``` |
||||
|
||||
## New custom dependency for libdl |
||||
|
||||
``` |
||||
dependency('dl') |
||||
``` |
||||
|
||||
will now check for the functionality of libdl.so, but first check if it is |
||||
provided in the libc (for example in libc on OpenBSD or in musl libc on linux). |
||||
|
||||
## pkgconfig.generate will now include variables for builtin directories when referenced |
||||
|
||||
When using the `variables:` family of kwargs to `pkgconfig.generate` to refer |
||||
to installed paths, traditionally only `prefix`, `includedir`, and `libdir` |
||||
were available by default, and generating a correct (relocatable) pkg-config |
||||
file required manually constructing variables for e.g. `datadir`. |
||||
|
||||
Meson now checks each variable to see if it begins with a reference to a |
||||
standard directory, and if so, adds it to the list of directories for which a |
||||
builtin variable is created. |
||||
|
||||
For example, before it was necessary to do this: |
||||
```meson |
||||
pkgconfig.generate( |
||||
name: 'bash-completion', |
||||
description: 'programmable completion for the bash shell', |
||||
dataonly: true, |
||||
variables: { |
||||
'prefix': get_option('prefix'), |
||||
'datadir': join_paths('${prefix}', get_option('datadir')), |
||||
'sysconfdir': join_paths('${prefix}', get_option('sysconfdir')), |
||||
|
||||
'compatdir': '${sysconfdir}/bash_completion.d', |
||||
'completionsdir': '${datadir}/bash-completion/completions', |
||||
'helpersdir': '${datadir}/bash-completion/helpers', |
||||
}, |
||||
install_dir: join_paths(get_option('datadir'), 'pkgconfig'), |
||||
) |
||||
``` |
||||
|
||||
Now the first three variables are not needed. |
||||
|
||||
## New keyword argument `verbose` for tests and benchmarks |
||||
|
||||
The new keyword argument `verbose` can be used to mark tests and benchmarks |
||||
that must always be logged verbosely on the console. This is particularly |
||||
useful for long-running tests, or when a single Meson test() is wrapping |
||||
an external test harness. |
||||
|
||||
## CMake support for versions <3.17.0 is deprecated |
||||
|
||||
Support for CMake versions below 3.17.0 is now deprecated for *both* CMake |
||||
dependencies and subprojects. |
||||
|
||||
## Removal of the RPM module |
||||
|
||||
Due to lack of interest, lack of maintainership, and lack of a clear purpose, |
||||
the RPM module has been removed. |
||||
|
||||
Users interested in one-shot tools to generate an RPM spec file template for |
||||
distro packaging, are encouraged develop an external tool that reads the |
||||
introspection data. |
||||
|
||||
For more details, see https://github.com/mesonbuild/meson/issues/9764 |
||||
|
||||
## CMake server API support is removed |
||||
|
||||
Support for the |
||||
[deprecated (since CMake 3.15)](https://cmake.org/cmake/help/latest/release/3.15.html#deprecated-and-removed-features) |
||||
and now |
||||
[removed (since CMake 3.20)](https://cmake.org/cmake/help/latest/release/3.20.html#deprecated-and-removed-features) |
||||
CMake server API is dropped from Meson. |
||||
|
||||
The new CMake minimum version for CMake subprojects is now CMake 3.14. |
||||
|
||||
## Rust proc-macro crates |
||||
|
||||
Rust has these handy things called proc-macro crates, which are a bit like a |
||||
compiler plugin. We can now support them, simply build a [[shared_library]] with |
||||
the `rust_crate_type` set to `proc-macro`. |
||||
|
||||
```meson |
||||
proc = shared_library( |
||||
'proc', |
||||
'proc.rs', |
||||
rust_crate_type : 'proc-macro', |
||||
install : false, |
||||
) |
||||
|
||||
user = executable('user, 'user.rs', link_with : proc) |
||||
``` |
||||
|
||||
## found programs now have a version method |
||||
|
||||
The return value of [[find_program]] can now check the exact version of the |
||||
found program, independent of the minimum version requirement. This can be used |
||||
e.g. to perform different actions depending on the exact version detected. |
||||
|
||||
## Minimum required Python version updated to 3.7 |
||||
|
||||
Meson now requires at least Python version 3.7 to run as Python 3.6 reached EOL |
||||
on December 2021. In practice this should only affect people developing on |
||||
Ubuntu Bionic, who will need to manually install python3.8 from the official |
||||
repositories. |
||||
|
||||
|
||||
## Added support for XML translations using itstool |
||||
|
||||
XML files can now be translated easier by using `itstool` via |
||||
`i18n.itstool_join()`. This ensures the XML is translated correctly |
||||
based on the defined ITS rules for the specific XML layout. |
||||
|
||||
## JNI System Dependency Modules |
||||
|
||||
The JNI system dependency now supports a `modules` keyword argument which is a |
||||
list containing any of the following: `jvm`, `awt`. |
||||
|
||||
```meson |
||||
jni_dep = dependency('jni', version: '>= 1.8.0', modules: ['jvm', 'awt']) |
||||
``` |
||||
|
||||
This will add appropriate linker arguments to your target. |
||||
|
||||
## New unstable wayland module |
||||
|
||||
This module can search for protocol xml files from the wayland-protocols |
||||
package, and generate .c and .h files using wayland-scanner. |
||||
|
||||
## Experimental command to convert environments to cross files |
||||
|
||||
Meson has a new command `env2mfile` that can be used to convert |
||||
"environment variable based" cross and native compilation environments |
||||
to Meson machine files. This is especially convenient for e.g. distro |
||||
packagers so they can easily generate unambiguous configuration files |
||||
for packge building. |
||||
|
||||
As an example here's how you would generate a cross file that takes |
||||
its settings from the `CC`, `CXX`, `CFLAGS` etc environment variables. |
||||
|
||||
meson env2mfile --cross --system=baremetal --cpu=armv7 --cpu-family=arm -o armcross.txt |
||||
|
||||
The command also has support for generating Debian build files using |
||||
system introspection: |
||||
|
||||
meson env2mfile --cross --debarch armhf -o debarmhf_cross.txt |
||||
|
||||
Note how you don't need to specify any system details, the command |
||||
gets them transparently via `dpkg-architecture`. |
||||
|
||||
Creating a native file is done in the same way: |
||||
|
||||
meson env2mfile --native -o current_system.txt |
||||
|
||||
This system will detect if the `_FOR_BUILD` environment variables are |
||||
enabled and then uses them as needed. |
||||
|
||||
With this you should be able to convert any envvar-based cross build |
||||
setup to cross and native files and then use those. This means, among |
||||
other things, that you can then run your compilations from any shell, |
||||
not just the special one that has all the environment variables set. |
||||
|
||||
As this functionality is still a bit in flux, the specific behaviour |
||||
and command line arguments to use are subject to change. Because of |
||||
this the main documentation has not yet been updated. |
||||
|
||||
Please try this for your use cases and report to us if it is working. |
||||
Patches to make the autodetection work on other distros and platforms |
||||
are also welcome. |
||||
|
||||
## Added optional '--allow-dirty' flag for the 'dist' command |
||||
|
||||
An optional `--allow-dirty` flag has been added to the `dist` command. |
||||
|
||||
Previously, if uncommitted changes were present, Meson would warn about |
||||
this but continue with the dist process. It now errors out instead. The |
||||
error can be suppressed by using the `--allow-dirty` option. |
||||
|
||||
## ldconfig is no longer run on install |
||||
|
||||
Due to various issues of fragility and concern that it doesn't predictably do |
||||
the right thing, meson no longer runs ldconfig during `meson install`, and |
||||
users who need it run should run it themselves, instead. |
||||
|
||||
## Added support for Texas Instruments MSP430 and ARM compilers |
||||
|
||||
Meson now supports the TI [MSP430](https://www.ti.com/tool/MSP-CGT) and |
||||
[ARM](https://www.ti.com/tool/ARM-CGT) toolchains. The compiler and linker are |
||||
identified as `ti` and `ti-ar`, respectively. To maintain backwards |
||||
compatibility with existing build definitions, the [C2000 |
||||
toolchain](https://www.ti.com/tool/C2000-CGT) is still identified as `c2000` and |
||||
`ar2000`. |
||||
|
||||
## cmake.configure_package_config_file can now take a dict |
||||
|
||||
The `configuration` kwarg of the `configure_package_config_file()` function |
||||
from the `cmake` module can now take a dict object, just like the regular |
||||
`configure_file()` function. |
||||
|
||||
## Deprecated `java.generate_native_header()` in favor of the new `java.generate_native_headers()` |
||||
|
||||
`java.generate_native_header()` was only useful for the most basic of |
||||
situations. It didn't take into account that in order to generate native |
||||
headers, you had to have all the referenced Java files. It also didn't take |
||||
into account inner classes. Do not use this function from `0.62.0` onward. |
||||
|
||||
`java.generate_native_headers()` has been added as a replacement which should account for the previous function's shortcomings. |
||||
|
||||
```java |
||||
// Outer.java |
||||
|
||||
package com.mesonbuild; |
||||
|
||||
public class Outer { |
||||
private static native void outer(); |
||||
|
||||
public static class Inner { |
||||
private static native void inner(); |
||||
} |
||||
} |
||||
``` |
||||
|
||||
With the above file, an invocation would look like the following: |
||||
|
||||
```meson |
||||
java = import('java') |
||||
|
||||
native_headers = java.generate_native_headers( |
||||
'Outer.java', |
||||
package: 'com.mesonbuild', |
||||
classes: ['Outer', 'Outer.Inner'] |
||||
) |
||||
``` |
||||
|
||||
## New option to choose python installation environment |
||||
|
||||
It is now possible to specify `-Dpython.install_env` and choose how python modules are installed. |
||||
|
||||
- `venv`: assume that a virtualenv is active and install to that |
||||
- `system`: install to the global site-packages of the selected interpreter |
||||
(the one that the venv module calls --system-site-packages) |
||||
- `prefix`: preserve existing behavior |
||||
- `auto`: autodetect whether to use venv or system |
||||
|
||||
## JDK System Dependency Renamed from `jdk` to `jni` |
||||
|
||||
The JDK system dependency is useful for creating native Java modules using the |
||||
JNI. Since the purpose is to find the JNI, it has been decided that a better |
||||
name is in fact "jni". Use of `dependency('jdk')` should be replaced with |
||||
`dependency('jni')`. |
||||
|
||||
## i18n.merge_file no longer arbitrarily leaves your project half-built |
||||
|
||||
The i18n module partially accounts for builds with NLS disabled, by disabling |
||||
gettext compiled translation catalogs if it cannot build them. Due to |
||||
implementation details, this also disabled important data files created via |
||||
merge_file, leading to important desktop files etc. not being installed. |
||||
|
||||
This overreaction has been fixed. It is no longer possible to have NLS-disabled |
||||
builds which break the project by not installing important files which have |
||||
nothing to do with NLS (other than including some). |
||||
|
||||
If you were depending on not having the Gettext tools installed and |
||||
successfully mis-building your project, you may need to make your project |
||||
actually work with NLS disabled, for example by providing some version of your |
||||
files which is still installed even when merge_file cannot be run. |
||||
|
||||
## All directory options now support paths outside of prefix |
||||
|
||||
Previously, Meson only allowed most directory options to be relative to prefix. |
||||
This restriction has been now lifted, bringing us in line with Autotools and |
||||
CMake. It is also useful for platforms like Nix, which install projects into |
||||
multiple independent prefixes. |
||||
|
||||
As a consequence, `get_option` might return absolute paths for any |
||||
directory option, if a directory outside of prefix is passed. This |
||||
is technically a backwards incompatible change but its effect |
||||
should be minimal, thanks to widespread use of `join_paths`/ |
||||
`/` operator and pkg-config generator module. |
||||
|
||||
## `meson install --strip` |
||||
|
||||
It is now possible to strip targets using `meson install --strip` even if |
||||
`-Dstrip=true` option was not set during configuration. This allows doing |
||||
stripped and not stripped installations without reconfiguring the build. |
||||
|
||||
## Support for ARM Ltd. Clang toolchain |
||||
|
||||
Support for the `armltdclang` compiler has been added. This differs from the |
||||
existing `armclang` toolchain in that it is a fork of Clang by ARM Ltd. and |
||||
supports native compilation. The Keil `armclang` toolchain only supports |
||||
cross-compilation to embedded devices. |
||||
|
||||
## structured_sources() |
||||
|
||||
A new function, `structured_sources()` has been added. This function allows |
||||
languages like Rust which depend on the filesystem layout at compile time to mix |
||||
generated and static sources. |
||||
|
||||
```meson |
||||
executable( |
||||
'main', |
||||
structured_sources( |
||||
'main.rs, |
||||
{'mod' : generated_mod_rs}, |
||||
) |
||||
) |
||||
``` |
||||
|
||||
Meson will then at build time copy the files into the build directory (if |
||||
necessary), so that the desired file structure is laid out, and compile that. In |
||||
this case: |
||||
|
||||
``` |
||||
root/ |
||||
main.rs |
||||
mod/ |
||||
mod.rs |
||||
``` |
||||
|
||||
## New custom dependency for OpenSSL |
||||
|
||||
Detecting an OpenSSL installation in a cross-platform manner can be |
||||
complicated. Officially, pkg-config is supported by upstream. Unofficially, |
||||
cmake includes a FindOpenSSL using a different name and which requires |
||||
specifying modules. |
||||
|
||||
Meson will now allow the pkg-config name to work in all cases using the following lookup order: |
||||
- prefer pkg-config if at all possible |
||||
- attempt to probe the system for the standard library naming, and retrieve the version from the headers |
||||
- if all else fails, check if cmake can find it |
||||
|
||||
## D features in `declare_dependency` |
||||
|
||||
`declare_dependency`accepts parameters for D specific features. |
||||
Accepted new parameters are `d_module_features` and `d_import_dirs`. |
||||
|
||||
This can be useful to propagate conditional compilation versions. E.g.: |
||||
|
||||
```meson |
||||
my_lua_dep = declare_dependency( |
||||
# ... |
||||
d_module_features: ['LUA_53'], |
||||
d_import_dirs: include_directories('my_lua_folder'), |
||||
) |
||||
``` |
||||
|
||||
## arch_independent kwarg in cmake.write_basic_package_version_file |
||||
|
||||
The `write_basic_package_version_file()` function from the `cmake` module |
||||
now supports an `arch_independent` kwarg, so that architecture checks in |
||||
the generated Package Version file are skipped, reproducing the behaviour of |
||||
CMake's [ARCH_INDEPENDENT](https://cmake.org/cmake/help/latest/module/CMakePackageConfigHelpers.html#command:write_basic_package_version_file) |
||||
option. |
||||
|
||||
## `dataonly` Pkgconfig Default Install Path |
||||
|
||||
The default install path for `dataonly` pkgconfig files has changed from |
||||
`${libdir}/pkgconfig` to `${datadir}/pkgconfig`. |
||||
|
||||
## JAR default install dir |
||||
|
||||
The previous default for `jar()` was `libdir`. With this release, it has been |
||||
changed to `datadir/java`. Please open an issue if this is not a sane default |
||||
for your system. |

## Bash completion scripts sourced in `meson devenv` |
||||
|
||||
If bash-completion scripts are being installed and the shell is bash, they will |
||||
be automatically sourced. |
||||
|
||||
## Setup GDB auto-load for `meson devenv` |
||||
|
||||
When GDB helper scripts (*-gdb.py, *-gdb.gdb, and *-gdb.csm) are installed with |
||||
a library name that matches one being built, Meson adds the needed auto-load |
||||
commands into `<builddir>/.gdbinit` file. When running gdb from top build |
||||
directory, that file is loaded by gdb automatically. |
||||
|
||||
## Print modified environment variables with `meson devenv --dump` |
||||
|
||||
With `--dump` option, all envorinment variables that have been modified are |
||||
printed instead of starting an interactive shell. It can be used by shell |
||||
scripts that wish to setup their environment themself. |
||||
|
||||
## New `method` and `separator` kwargs on `environment()` and `meson.add_devenv()` |

## Added optional '--allow-dirty' flag for the 'dist' command |

|

An optional `--allow-dirty` flag has been added to the `dist` command. |

Previously, if uncommitted changes were present, Meson would warn about |

this but continue with the dist process. It now errors out instead. The |

error can be suppressed by using the `--allow-dirty` option. |

## Experimental command to convert environments to cross files |
||||
|
||||
Meson has a new command `env2mfile` that can be used to convert |
||||
"environment variable based" cross and native compilation environments |
||||
to Meson machine files. This is especially convenient for e.g. distro |
||||
packagers so they can easily generate unambiguous configuration files |
||||
for packge building. |
||||
|
||||
As an example here's how you would generate a cross file that takes |
||||
its settings from the `CC`, `CXX`, `CFLAGS` etc environment variables. |
||||
|
||||
meson env2mfile --cross --system=baremetal --cpu=armv7 --cpu-family=arm -o armcross.txt |
||||
|
||||
The command also has support for generating Debian build files using |
||||
system introspection: |
||||
|
||||
meson env2mfile --cross --debarch armhf -o debarmhf_cross.txt |
||||
|
||||
Note how you don't need to specify any system details, the command |
||||
gets them transparently via `dpkg-architecture`. |
||||
|
||||
Creating a native file is done in the same way: |
||||
|
||||
meson env2mfile --native -o current_system.txt |
||||
|
||||
This system will detect if the `_FOR_BUILD` environment variables are |
||||
enabled and then uses them as needed. |
||||
|
||||
With this you should be able to convert any envvar-based cross build |
||||
setup to cross and native files and then use those. This means, among |
||||
other things, that you can then run your compilations from any shell, |
||||
not just the special one that has all the environment variables set. |
||||
|
||||
As this functionality is still a bit in flux, the specific behaviour |
||||
and command line arguments to use are subject to change. Because of |
||||
this the main documentation has not yet been updated. |
||||
|
||||
Please try this for your use cases and report to us if it is working. |
||||
Patches to make the autodetection work on other distros and platforms |
||||
are also welcome. |

## Deprecated `java.generate_native_header()` in favor of the new `java.generate_native_headers()` |
||||
|
||||
`java.generate_native_header()` was only useful for the most basic of |
||||
situations. It didn't take into account that in order to generate native |
||||
headers, you had to have all the referenced Java files. It also didn't take |
||||
into account inner classes. Do not use this function from `0.62.0` onward. |
||||
|
||||
`java.generate_native_headers()` has been added as a replacement which should account for the previous function's shortcomings. |

```java |

package com.mesonbuild; |

public class Outer { |

private static native void outer(); |

public static class Inner { |
||||
private static native void inner(); |
||||
} |
||||
} |
||||
``` |
||||

## i18n.merge_file no longer arbitrarily leaves your project half-built |
||||
|
||||
The i18n module partially accounts for builds with NLS disabled, by disabling |
||||
gettext compiled translation catalogs if it cannot build them. Due to |
||||
implementation details, this also disabled important data files created via |
||||
merge_file, leading to important desktop files etc. not being installed. |
||||
|
||||
This overreaction has been fixed. It is no longer possible to have NLS-disabled |
||||
builds which break the project by not installing important files which have |
||||
nothing to do with NLS (other than including some). |
||||
|
||||
If you were depending on not having the Gettext tools installed and |
||||
successfully mis-building your project, you may need to make your project |
||||
actually work with NLS disabled, for example by providing some version of your |
||||
files which is still installed even when merge_file cannot be run. |

- prefer pkg-config if at all possible |

- attempt to probe the system for the standard library naming, and retrieve the version from the headers |
||||
- if all else fails, check if cmake can find it |

## pkgconfig.generate will now include variables for builtin directories when referenced |
||||
|
||||
When using the `variables:` family of kwargs to `pkgconfig.generate` to refer |
||||
to installed paths, traditionally only `prefix`, `includedir`, and `libdir` |
||||
were available by default, and generating a correct (relocatable) pkg-config |
||||
file required manually constructing variables for e.g. `datadir`. |
||||
|
||||
Meson now checks each variable to see if it begins with a reference to a |
||||
standard directory, and if so, adds it to the list of directories for which a |
||||
builtin variable is created. |
||||
|
||||
For example, before it was necessary to do this: |
||||
```meson |
||||
pkgconfig.generate( |
||||
name: 'bash-completion', |
||||
description: 'programmable completion for the bash shell', |
||||
dataonly: true, |
||||
variables: { |
||||
'prefix': get_option('prefix'), |
||||
'datadir': join_paths('${prefix}', get_option('datadir')), |
||||
'sysconfdir': join_paths('${prefix}', get_option('sysconfdir')), |

|

'compatdir': '${sysconfdir}/bash_completion.d', |

'completionsdir': '${datadir}/bash-completion/completions', |

'helpersdir': '${datadir}/bash-completion/helpers', |

||||
install_dir: join_paths(get_option('datadir'), 'pkgconfig'), |
