In ‘core-updates’ there’s a new ‘validate-runpath’ phase that checks all the ELF binaries produced and fails if one of them has a dependency (DT_NEEDED) that cannot be found in its RUNPATH. It uses (guix elf) and the new (guix build gremlin).
So now the “dangling .so references” bugs really need to be fixed. ;-) A few RUNPATH problems were fixed in ‘core-updates’, mostly related to cross-compilation where binaries never had a valid RUNPATH due to the lack of a cross ‘ld-wrapper’ to add ‘-rpath’ flags as we do natively. Feedback welcome! Ludo’.
