Worked on enhancing build stability for the compiler-explorer repository by addressing compatibility issues with newer versions of the Qt framework. Focused on C++ development, the work involved identifying and resolving a recurring linking failure that affected users relying on Qt versions later than 6.4.2. The solution introduced pcre2 as a required dependency, ensuring successful builds and reducing user-facing errors. This targeted bug fix improved the reliability of compiler-explorer across diverse Qt toolchains and laid the foundation for future updates. The approach aligned with best practices in dependency management and demonstrated a methodical focus on robust, maintainable C++ and Qt integration.
