1. 下载代码：http://www.apuebook.com/code3e.html
2. 安装依赖库：sudo apt-get install libbsd-dev
3. 进入下载目录make
4. 复制头文件和动态链接库
sudo cp ./include/apue.h /usr/include/sudo cp ./lib/libapue.a /usr/local/lib/
sudo cp ./lib/libapue.a /usr/lib/
5. 设置错误文件error.h
#include "apue.h"#include <errno.h> /* for definition of errno */#include <stdarg.h> /* ISO C variable aruments */static void err_doit(int, int, const char *, va_list);/* * Nonfatal error related to a system call. * Print a message and return. */void err_ret(const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(1, errno, fmt, ap); va_end(ap);}/* * Fatal error related to a system call. * Print a message and terminate. */void err_sys(const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(1, errno, fmt, ap); va_end(ap); exit(1);}/* * Fatal error unrelated to a system call. * Error code passed as explict parameter. * Print a message and terminate. */void err_exit(int error, const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(1, error, fmt, ap); va_end(ap); exit(1);}/* * Fatal error related to a system call. * Print a message, dump core, and terminate. */void err_dump(const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(1, errno, fmt, ap); va_end(ap); abort(); /* dump core and terminate */ exit(1); /* shouldn't get here */}/* * Nonfatal error unrelated to a system call. * Print a message and return. */void err_msg(const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(0, 0, fmt, ap); va_end(ap);}/* * Fatal error unrelated to a system call. * Print a message and terminate. */void err_quit(const char *fmt, ...){ va_list ap; va_start(ap, fmt); err_doit(0, 0, fmt, ap); va_end(ap); exit(1);}/* * Print a message and return to caller. * Caller specifies "errnoflag". */static void err_doit(int errnoflag, int error, const char *fmt, va_list ap){ char buf[MAXLINE]; vsnprintf(buf, MAXLINE, fmt, ap); if (errnoflag) snprintf(buf+strlen(buf), MAXLINE-strlen(buf), ": %s", strerror(error)); strcat(buf, "\n"); fflush(stdout); /* in case stdout and stderr are the same */ fputs(buf, stderr); fflush(NULL); /* flushes all stdio output streams */}
6. 注销，重启
7. 代码文件
#include "apue.h"#include "error.h"
