[Mageia-dev] Conflict between glibc and kernel headers ?

[Guillaume Rousse]

I have the following error while trying to build wpa_supplicant:

In file included from /usr/include/linux/sysinfo.h:4:0,
                  from /usr/include/linux/kernel.h:4,
                  from /usr/src/madwifi/include/compat.h:69,
                  from ../src/drivers/driver_madwifi.c:37:
/usr/include/linux/types.h:31:25: erreur: conflicting types for ‘u_int64_t’

/usr/include/sys/types.h:203:1: note: previous declaration of 
‘u_int64_t’ was here
make: *** [../src/drivers/driver_madwifi.o] Erreur 1

If I'm understanding it correctly, there would be a mismatch between 
/usr/include/linux/types.h (from the kernel) and 
/usr/include/sys/types.h (from glibc). However, it's a bit difficult to 
figure how they differ/conflict, as both declaration heavily relies on 
preprocessing dark magic...

glibc version:
# define __u_intN_t(N, MODE) \
   typedef unsigned int u_int##N##_t __attribute__ ((__mode__ (MODE)))
__u_intN_t (64, __DI__);

kernel version:
typedef __u64 __bitwise __le64;

So ?
