进程小问题

[thesecretblue]

#include<stdio.h>
int main()
{ int pid;
pid=fork();
if(pid==0) {
printf("I am the child.\n");
execl("/bin/ls¡±,¡±ls",0);
perror("exec error.\n");
}
else if(pid>0)
printf("I am the parent.\n");
else printf("fork failed.\n");
printf("program end.\n");
return 0;
}

编译时出现的错误：
cc -o exe-os131 os131.c
os131.c: In function ‘main’:
os131.c:8: warning: not enough variable arguments to fit a sentinel

请教一下，该如何解决？？

#include <stdio.h>
#include<unistd.h>
int main()
{ int pid;
pid=fork();
if(pid==0) {
printf("I am the child.\n");
execl("/bin/ls¡±,¡±ls",0);
perror("exec error.\n");
}
else if(pid>0)
printf("I am the parent.\n");
else printf("fork failed.\n");
printf("program end.\n");
return 0;
}

os131.c: In function ‘main’:
os131.c:8: warning: not enough variable arguments to fit a sentinel
警告是：没有足够的变量来满足

请确认你的编译器是否安装正确！

肯定正确，
因为我是在vi下编辑的，用了很多次了，很好用的。
