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.

Modify install prefix from meson script

I need to modify install prefix option in meson build script... My idea is, when the user select some special option, the install prefix is getting from external tool (specifically, using ${CORSS}gcc -print-sysroot)
