Parfois des erreurs se produisent lorsqu'on compile à la suite d'une passe précédente, il est recommandé de créer un nouveau dossier et de supprimer la précédente glibc compilé mais aussi de remplacer intégralement le contenu du dossier /usr/include par# le contenu du dossier issu de l'extraction des en-têtes du noyau.
