Dear developers,
I am excited to announce that SageMath now supports the Meson build system! This modern alternative to Autotools brings several key advantages: - *Faster Builds* – Meson significantly reduces configuration and compilation time due to better parallelism (some benchmark claim up to 20% reduction of compilation time; in my experience it was closer to 10%) - *Better Incremental Builds* – Only necessary files are recompiled, speeding up development. In particular, Meson will automatically recompile Cython files when they change - without the need to run `sage -b` or similar commands. The workflow is thus the same as for Python files: a) make the necessary changes b) save the file c) run the tests (which then automatically use the freshly recompiled version) - *Easier Installation* – Meson works smoothly with the standard Python packaging systems, so that the installation of Sagemath using Meson is a simple `pip install .`; no more bootstrap + configure + make. - *Cross-Platform * –One of the biggest advantages of Meson is that it natively supports Windows (in addition to Linux and MacOS, of course). This opens up a direct road to natively use Sage on Windows; in fact, https://github.com/sagemath/sage/pull/38872 is the first step towards this goal. - *Easier Dependency Management* – External dependencies / system packages are detected more reliably (caveat: some of the extra feature checks are not yet reimplemented in Meson). *Quick Start* To build SageMath with Meson, install the required dependencies (either using your system package manager or conda), then use: `pip install --no-build-isolation --editable .` Start Sage with `./sage` and run tests using `./sage -t`, as usually.
