描述

I need to run code that writes files in compiler.run(). Turns out the current working directory is the same as for the meson (or ninja) invocation. If I don't manually clean up the generated files in the code being run, they're left behind.

I'd like to be able to pass the workdir to compiler.run() not unlike test() workdir, and/or have the code executed in a temporary directory that's automatically discarded afterwards. Having to do this yourself in a C or C++ code snippet is tedious at best.

研究方向
Investigate the implementation of compiler.run() in Meson, likely in mesonbuild/compilers/compilers.py. The goal is to add a workdir parameter or automatic temporary directory cleanup. Review the existing test() workdir mechanism for reference. Ensure backward compatibility.
