Questions tagged [meson-build]

Meson is a build configuration system used to build C/C++, Java, Rust, Objective-C/C++, and Fortran projects. It uses a DSL to describe project targets. This tag is for questions about the meson build system and DSL syntax or usage.

Meson is a build configuration system used to build C/C++, Java, Rust, Objective-C/C++, and Fortran.

It is conceptually similar to MPC or CMake, and draws strengths from them as well as SCons, Autoconf.

Project targets are described using a non-Turing complete DSL. Despite being implemented in Python, no direct calls into Python are permitted, nor is any Python syntax directly supported. Strictly speaking, the Meson processor could be reimplemented in any language and would be able to handle the DSL without assistance from an embedded Python interpreter.

For more information about Meson, see their home page. To contribute, see their source code repository on github.com.

How do I speed up Meson build when many targets use the same C++ sources

I have a new meson project with 58 targets. Many of them use the same *.cc files, and meson builds each *.cc file once for each target, which is much slower than autotools. Also, the compile flags should be the same between targets, so in theory…
