"extern int errno;" doesn't exist any more since ages (maybe even for libc5, I'd guess). Since errno must be thread-local, it used to be declared as: #define errno (*(__errno_location())) but from the messages I guess it's being declared as something like (I don't know the exact syntax): extern __thread int errno; So don't declare it,nor include <linux/errno.h>; include <errno.h> instead, which should contain the correct definition.
