This way there are a lot of great God, I hope to be able to read this term "UNIX Network Programming Volume: Sockets Networking API", the full text of this blog Transfers from the bloggers, but for which a supplementary explanation wrong place, measured success.
First, download the source code and compile
the source code Download: http://www.unpbook.com/ , download files get unpv13e.tar.gz
Compilation step:
decompression zxvf unpv13e.tar.gz
tar zxvf unpv13e.tar.gz
Enter unpv13e folder
cd ./unpv13e
./configure //如果权限不够可以chmod改权限
Compiled lib file
cd lib
make //出现大量warning,忽略之
cd ../libfree
make //若出现错误，看后面横线内解决办法。无则跳过
Error follows:
inet_ntop.c: the In function 'inet_ntop':
inet_ntop.c: 60:. 9: error: argument 'size' does match the prototype Not
size_t size;
case in libfree directory, modified
vim inet_ntop.c //将第60行的 size_t size 改成 socklen_t size;
That re-make to fix the error.
Continue with the following command:
cd ../libgai
make
Second, the environment to build
modify unp.h, the #include "../config.h" changed to #include "config.h", as follows:
1、cd .. //回到主目录
2、sudo vim lib/unp.h
Continue, copy header files to include
sudo cp config.h /usr/local/include
sudo cp lib/unp.h /usr/local/include
Copy in the library
sudo cp libunp.a /usr/local/lib
This code on unix network programming book can be compiled.
Third, the test sample code
to examples intro / daytimetcpcli.c example:
Compile daytimetcpcli.c file
cd ./intro
gcc daytimetcpcli.c -o daytimetcpcli -lunp
run
./daytimetcpcli 127.0.0.1
When the test will receive an error
connect error:Connection refused
Ubuntu system needs to open at daytime, control may be implemented by a service connection request xinetd.
No xinetd.d, you need to install
sudo apt-get install xinetd
Then edit the daytime
vim daytime
The two later disable the file into yes no, save and exit
reboot xinted.d
service xinetd restart
Test daytimetcpcli example again,
./daytimetcpcli 127.0.0.1
Get the right result
