memcpy(utsname()->machine, "i486", 5); the 2 strings are x86_64\0 i486\0 copying 4 characters resulted in i48664\0. just need to copy that \0 and it'll be i486\04. the \0 terminates the string. _______________________________________________ Clfs-support mailing list Clfs-support@lists.cross-lfs.org http://lists.cross-lfs.org/cgi-bin/mailman/listinfo/clfs-support
