During June 2026, work centered on enhancing the build system for the spack/spack-packages repository by introducing explicit C and C++ compiler dependencies to the RecolaSm package. This feature-driven update improved compatibility across diverse user toolchains, ensuring more reliable builds for downstream users. The technical approach involved updating Python-based packaging metadata to declare these new dependencies, leveraging skills in build systems and package management. Collaboration was maintained through co-authored commits, preserving transparency in the development process. No major bug fixes were reported during this period, with efforts focused on expanding build capabilities and strengthening the reliability of package installation workflows.
