在linux下编译这个程序为什么不过

来源: 互联网发布时间：2015-10-25

本文导语: #include "ourhdr.h" int main(void) {int c; while((c=getc(stdin))!=EOF) if(putc(c,stdout)==EOF) err_sys("output error"); if(ferror(stdin)) err_sys("input error"); exit(0); } 这是unix环境高级编程里的程序1-3，为什么我不能编译通过，是什么问题，请高手...

#include "ourhdr.h"
int
main(void)
{int c;
while((c=getc(stdin))!=EOF)
if(putc(c,stdout)==EOF)
err_sys("output error");
if(ferror(stdin))
err_sys("input error");
exit(0);
}

这是unix环境高级编程里的程序1-3，为什么我不能编译通过，是什么问题，请高手指教，这是我在linux下编译的第一个程序，所以请大虾们尽量说的详细多谢了

我也正在看，那个头文件和ourhdr.c都没有，肯定失败。

你没有编译 ourhdr.c 文件吧，找不到ourhdr.h 和 err_sys（）, 到网上搜索一下源代码吧。

//test.cpp
#include
int main(void)
{
cout
