Preparation

git clone https://github.com/unpbook/unpv13e

Configure the makefile for your system:

CC=gcc CFLAGS=-w CPPFLAGS=-w ./configure    

In archlinux, if you use ./configure directly, you will get Wimplicit compile error in the following steps.

Build the dependence library.

cd lib
make
cd ../libfree
make
cd ../libroute
make

You can test by using the sample program

cd ../intro
make daytimetcpcli
./daytimetcpcli 127.0.0.1

If you get error

connect error: Connection refused

You need to install xinetd, configure it and start the service

yay -S xinetd
nvim /etc/xinetd.d/daytime # set `disable` from `yes` to `no`
systemctl start xinetd

And run daytimetcpcli again, you will get something like

16 MAY 2024 14:09:07 CST

Then, you are all set.
