Then find libapue.a from the Apue.2e/lib folder, find apue.h from the Apue.2e/include folder, and copy both to the source directory (the directory where you wrote your. c file), enter

[Email protected] test]# Gcc-o main MAIN.C libapue.a

Compilation succeeded, input

[Email protected] test]#./main/dev

can be run.

Appendix:

Run the program code as follows:

#include"apue.h"#include<dirent.h>intMainintargcChar*argv[]) {DIR*DP; structDirent *Dirp; if(argc!=2) Err_quit ("Usage:ls Directory_name"); if(DP = Opendir (argv[1]))==NULL) Err_sys ("can ' t open%s", argv[1]);  while((Dirp=readdir (DP))! =NULL) printf ("%s\n",dirp->d_name);    Closedir (DP); Exit (0);}
