linux/ext2_fs.h有什么问题? [英] What's wrong with linux/ext2_fs.h?

问题描述

cat main.c

cat main.c

#include <stdio.h>
#include <stdlib.h>
#include <linux/ext2_fs.h>

int main(int argc, char** argv) {

    return (EXIT_SUCCESS);
}

这是我的输出...

gcc main.c在main.c:3包含的文件中:

gcc main.c In file included from main.c:3:

/usr/include/linux/ext2_fs.h:在函数"ext2_mask_flags"中:

如果我删除 #include< linux/ext2_fs.h> ，程序将成功编译...

If I remove #include <linux/ext2_fs.h> the program compiles successfully...
