This fails to compile on systems without MS_MOVE, like openSUSE 11.4. $ grep -r MS_MOVE /usr/include/
At that point glibc did not provide MS_MOVE.

So what should be done?
so sys/mount.h is present and does provide the symbol. And yet, compiler does not see it. Anything suspicious on sys/mount.h that would make the compiler not see it (e.g. #ifdef). Meanwhile, does this help? diff --git i/src/util/virfile.c w/src/util/virfile.c index bf8099e34..a900bd405 100644 --- i/src/util/virfile.c +++ w/src/util/virfile.c @@ -34,6 +34,9 @@ #include <sys/wait.h> #if defined(HAVE_SYS_MOUNT_H) # include <sys/mount.h> +# if defined(__linux__) +# include <linux/fs.h> +# endif #endif #include <unistd.h> #include <dirent.h> Michal
