Wen Zhecheng contributed to the sched-ext/scx repository by addressing a build system issue that was hindering successful compilation for users and contributors. He identified and corrected a missing hyphen in a Meson build command within the README.md, which previously caused the build system to misidentify the paths for the libbpf library and header files. By updating the Markdown documentation and refining the build system configuration, Wen ensured that both continuous integration and local development environments could reliably detect dependencies and complete builds. This targeted fix improved onboarding for new developers and enhanced the overall reliability of the build process.
