Error when an installed static library links to internal custom target When an installed static library A links to an internal static library B built using a custom_target(), raise an error instead of a warning. This is because to be usable, A needs to contain B which would require to extract the archive to get its objects files. This used to work, but was printing a warning and was installing a broken static library, because we used to overlink in many cases, and that got fixed in Meson 1.2.0. It now fails at link time with symbols from the custom target not being defined. It's better to turn the warning into a hard error at configure time. While at it, noticed this situation can happen for any internal custom or rust target we link to, recursively. get_internal_static_libraries_recurse() could be called on CustomTarget objects which do not implement it, and even if we did not call that method, it would still fail when trying to call extract_all_objects() on it. Fixes: #12006
Meson is available on PyPi, so it can be installed with pip3 install meson. The exact command to type to install with pip can vary between systems, be sure to use the Python 3 version of pip.
If you wish you can install it locally with the standard Python command:
python3 -m pip install meson
For builds using Ninja, Ninja can be downloaded directly from Ninja GitHub release page or via PyPi
python3 -m pip install ninja
More on Installing Meson build can be found at the getting meson page.
Meson can be run as a Python zip app. To generate the executable run the following command:
./packaging/create_zipapp.py --outfile meson.pyz --interpreter '/usr/bin/env python3' <source checkout>
Meson requires that you have a source directory and a build directory and that these two are different. In your source root must exist a file called meson.build. To generate the build system run this command:
meson setup <source directory> <build directory>
Depending on how you obtained Meson the command might also be called meson.py instead of plain meson. In the rest of this document we are going to use the latter form.
You can omit either of the two directories, and Meson will substitute the current directory and autodetect what you mean. This allows you to do things like this:
cd <source root> meson setup builddir
To compile, cd into your build directory and type ninja. To run unit tests, type ninja test.
More on running Meson build system commands can be found at the running meson page or by typing meson --help.
We love code contributions. See the contribution page on the website for details.
The channel to use is #mesonbuild either via Matrix (web interface) or OFTC IRC.
More information about the Meson build system can be found at the project's home page.
