Salut,

J' essaye de faire de la compilation croisé pour les processeurs arm (je suis sur x86)

Etant sur une gentoo j' ai suivit ce howto:
==>http://dev.gentoo.org/~vapier/CROSS-COMPILE-HOWTO<==
Là où ça se corse c'est pour la glibc. La compilation s' arrête avec:

Code :

C'est un bug dans gcc ... Je te conseille de télécharger directement une toolchain complète précompilée ça t'évitera des ennuis
