In file included from cp.c:1:0:
stat.h:8:3: error: unknown type name 'uint'
   uint ino;    // Inode number
   ^~~~
stat.h:10:3: error: unknown type name 'uint'
   uint size;   // Size of file in bytes
   ^~~~
<builtin>: recipe for target 'cp.o' failed
make: *** [cp.o] Error 1

这里的cp.c的文件为：

#include "stat.h"
#include "tyeps.h"
#include "user.h"
#include "fcntl.h"
char buf[512];
int
main(int argc, char *argv[])
{
    int fd0, fd1, n;
    if(argc <= 2){
        printf(1, "Need 2 arguments! \n");
        exit();
    }

    if((fd0 = open(argv[1], O_RDONLY)) < 0){
        printf(1, "cp: cannot open %s\n", argv[1] ) ;
        exit();
    }
    if((fd1 = open(argv[2], O_CREATE|O_RDWR)) < 0){
        printf(1, "cp: cannot open %s\n", argv[2]);
        exit();
    }
    while ( ( n = read ( fd0, buf, sizeof(buf))) > 0 ){
        write ( fd1, buf, n );
    }
    close(fd0);
    close(fd1);
    exit();
}

解决方法：我们只需要将头文件tyeps.h在stat.h之前引入即可。
修改为：

#include "tyeps.h"
#include "stat.h"
#include "user.h"
#include "fcntl.h"
char buf[512];
int
main(int argc, char *argv[])
{
    int fd0, fd1, n;
    if(argc <= 2){
        printf(1, "Need 2 arguments! \n");
        exit();
    }

    if((fd0 = open(argv[1], O_RDONLY)) < 0){
        printf(1, "cp: cannot open %s\n", argv[1] ) ;
        exit();
    }
    if((fd1 = open(argv[2], O_CREATE|O_RDWR)) < 0){
        printf(1, "cp: cannot open %s\n", argv[2]);
        exit();
    }
    while ( ( n = read ( fd0, buf, sizeof(buf))) > 0 ){
        write ( fd1, buf, n );
    }
    close(fd0);
    close(fd1);
    exit();
}
