《UNIX网络编程》: source code 编译

查 Ubuntu 版本

$ cat /proc/version
Linux version 5.8.0-53-generic (buildd@lcy01-amd64-012) 
(gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, 
GNU ld (GNU Binutils for Ubuntu) 2.34) 
#60~20.04.1-Ubuntu SMP 

开始编译

cd unpv13e/

按 README 指引进行

cd ../intro    # build and test a basic client program
make daytimetcpcli

Connection refused 错误

4. 再开个窗口, 编译运行同一目录下 server 程序

make daytimetcpsrv

/intro$ make daytimetcpsrv
gcc -I../lib -g -O2 -D_REENTRANT -Wall   -c -o daytimetcpsrv.o daytimetcpsrv.c
In file included from ../lib/unp.h:48,

      |  ^~~~~~~
gcc -I../lib -g -O2 -D_REENTRANT -Wall -o daytimetcpsrv daytimetcpsrv.o ../libunp.a -lpthread

intro$ sudo ./daytimetcpsrv

Sorry, try again.

不用 sudo 也可以

5. 在 第 1 个 窗口 再 运行 刚才的 client 程序

$ ./daytimetcpcli 127.0.0.1
