Comment activer le support RELRO?
Nous avons essayé de construire un système LFS sur 12.04 64 bits. Dans l'étape de configuration de glibc, je reçois l'erreur
configure: error: éditeur de liens avec -z relro support requis
Comment puis-je activer le support RELRO?

J'ai eu le même problème lors de mon installation (sur Debian), je l'ai résolu en installant gawk et en l'utilisant à la place de mawk. Cela fonctionnera peut-être aussi pour vous.
