编译 QIHUA-X40I 报错如下：
./…/misc/create_inode.c:395:18: error: conflicting types for ‘copy_file_range’ static errcode_t copy_file_range(ext2_filsys fs, int fd, ext2_file_t e2_file, ^ In file included from ./…/misc/create_inode.c:19:0: /usr/include/unistd.h:1110:9: note: previous declaration of ‘copy_file_range’ was here ssize_t copy_file_range (int __infd, __off64_t *__pinoff, ^
解决办法： buildroot-2017.02.3/output/build/host-e2fsprogs-1.43.3/misc/create_inode.c 屏蔽掉 #include <unistd.h>
