unp.h for Socket Networking API : Unix Network Programming?

Question

PLEASE HELP: I Just started reading the book Unix Network programming : The Socket Networking API (by Richard Stevens). if anyone can tell me what to do with the unpv12ep-0.2.tar.gz file that I downloaded from www.kegel.com so that it does not give me errors, I'd be thrilled. I use Linux (Ubuntu 11.10), I have already installed autoconfig and I've run ./config on the unpacked unpv12ep-0.2. There are a couple of patch files but I have no idea how to use them.

Besides below are the errors that I get in terminal

Apart from that is there any other simpler method that I can use so that I can run the programms in the book?

Answer 1

Type "patch -p# < patch_file" in the directory that you want to patch, where # is the directory level to apply the patch to (usually 0 or 1).

Answer 2

Perhaps if you have a specific question, we could be more helpful. I'm sure you will find c to be a very powerful programming language for both application and network programming. Have a nice Day!

Answer 3

I don't know about the specific thing your trying to compile but some advice about make



Do "make" in the same directory that you did "./configure"



You usually need to run make as root so try "sudo make" or "su" then "make"
