1 You may get this error in a modern GNU system. 2 Check out the preprocessed source (-ncspp option), and search 3 for `int8_t'. If you see a line like 4 5 typedef int int8_t __attribute__ ((__mode__ (QI))); 6 7 You've got it. This is serious braindamage from glibc (again). 8 Please edit the file /usr/include/sys/types.h. It sais: 9 10 #if !__GNU_PREREQ (2,7) 11 ... good typedefs 12 #else 13 ... braindamaged typedefs 14 #endif 15 16 Change the if to 17 18 #if !__GNU_PREREQ (2,7) || defined __NCC__ 19 20 That's perfectly safe.
