Revert PR12972 as a regression. Revert "interpreter: when overriding a dependency make its name match" This reverts commit b1340e9bb1f243e4de8f2d89415a45ade476a3dc. Revert "dependency: define equality and hash operators for Dependency" This reverts commit 6d713e40f81512eadb0cc4654408d90cb22ba774. This caused some projects to fail to build, such as libplacebo and libepoxy. Taking libplacebo as the example, the produced build.ninja does not include libvulkan.so as a linker input for src/libplacebo.so.338. We are probably getting dependency hashing wrong somewhere. Unsure where exactly and unsure how to create a test case. We are also deep into rc2. Revert it for now and try to re-land these changes for 1.6. Bug: https://bugs.gentoo.org/935443 Fixes: #13352
Latest Meson version supporting previous Python versions:
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.
