title: Release 1.0.0 short-description: Release notes for 1.0.0 ...
Meson 1.0.0 was released on 23 December 2022
prefix
kwargs accepts arraysThe prefix
kwarg that most compiler check functions support now accepts an array in addition to a string. The elements of the array will be concatenated separated by a newline.
This makes it more readable to write checks that need multiple headers to be included:
cc.check_header('GL/wglew.h', prefix : ['#include <windows.h>', '#include <GL/glew.h>'])
instead of
cc.check_header('GL/wglew.h', prefix : '#include <windows.h>\n#include <GL/glew.h>'])
-Wnon-virtual-dtor
is no longer implied by meson setup -Dwarning_level=1
.
When cross compiling, the developer environment now sets all environment variables for the HOST machine. It now also sets QEMU_LD_PREFIX
to the sys_root
value from cross file if property is defined. That means that cross compiled executables can often be run transparently on the build machine, for example when cross compiling for aarch64 linux from x86_64 linux.
A new argument --workdir
has been added, by default it is set to build directory. For example, meson devenv -C builddir --workdir .
can be used to remain in the current dir (often source dir) instead.
--dump
now prints shell commands like FOO="/prepend/path:$FOO:/append/path"
, using the literal $FOO
instead of current value of FOO
from environment. This makes easier to evaluate those expressions in a different environment.
java.generate_native_headers
, rename to java.native_headers
The functions operate in the exact same way. The new name matches more with Meson function name styling.
The bindgen
method of the rust
module now accepts a dependencies argument. Any include paths in these dependencies will be passed to the underlying call to clang
, and the call to bindgen
will correctly depend on any generated sources.
Most other cases of include_directories accept strings as well as IncludeDirectory
objects, so lets do that here too for consistency.
Mesa is using the rust module in production, so it's time to mark it as stable.
in
operator for stringsin
and not in
operators now works on strings, in addition to arrays and dictionaries.
fs = import('fs') if 'something' in fs.read('somefile') # True endif
warning-level=everything
optionThe new everything
value for the built-in warning_level
enables roughly all applicable compiler warnings. For clang and MSVC, this simply enables -Weverything
or /Wall
, respectively. For GCC, meson enables warnings approximately equivalent to -Weverything
from clang.
