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

Thu Aug 9 17:18:03 CEST 2012

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:

+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 ?
