Jan 1, 2026January 2026: Delivered critical enhancements to the HDF-EOS2 package in the spack-packages repository, significantly improving reliability, compatibility, and maintainability. Implemented archive URL fix, added Fortran support, resolved HDF4 linking issues, and introduced compiler flags for compatibility with newer compilers. Updated maintainers and migrated download method to a web raw interface, reducing downtime risk and API fragility. Built robust configuration handling by ensuring dependency library directories are passed to configure, setting CC via h4cc to stabilize HDF4 linking, and adding an explicit GCC 14+ conflict to prevent breakages. These changes broaden platform coverage, enhance user experience, and streamline ongoing maintenance.
