This code below fixes linking error when compiled with these * compilers * * Affected distributions (incomplete list): * - Ubuntu 6.10, 7.04 */ void __stack_chk_fail_local (void); void __stack_chk_fail_local (void) { } --------------------------------- --------------------------------- L'email della prossima generazione?
