There's a bug in the old RedHat release: Bug 1476120 - glibc headers don't include linux/falloc.h, and therefore doesn't include fallocate() flags [1] How about adding "#include <linux/falloc.h>" ahead of fcntl.h? I'm quite lazy to update my host and using CentOS 7.2.1511, then it failed to compile due to this bug. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1476120 Thanks, Yongseok
