makefile errors

[jamesbon]

The network programming book of Richard Stevens had some errors in its functions.
Volume three code is available on internet as ttcpcliserv.tar
http://www.kohala.com/start/ttcpcliserv.tar
I found many example codes on this tar ball were using
err_sys and err_quit functions which were defined in the header
as file cliserv.h as

void err_quit(const char *, ...);
void err_sys(const char *, ...);
I could not understand above type of declaration of err_quit and err_sys (never seen such a function definition)
Replaced these words by printf in all c codes of above tar ball


sed -i 's/err_sys/printf/g' ./*.c
sed -i 's/err_quit/printf/g' ./*.cThe programs which I have read with first chapter of Vol3 of book
now seem to have worked and the header file cliserv.h which was included in each source code of example
of book
had declaration of
including the header files as


#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>


so I added this to each c file of that tar ball.So till now all the codes which I have tried to work or make work have worked till here.

Now the actual question begins e tar ball is coming with a
Makefile to be able to compile the source codes with examples in book with make.
When I compile that Makefile I get some errors what should I modify in the Makefile if any one can understand I am giving the Makefile and the corresponding errors

What should I modify in Makefile to make it work?

void err_quit(const char *, ...);
void err_sys(const char *, ...);
I could not understand above type of declaration of err_quit and err_sys (never seen such a function definition)That is a prototype for a function with a variable number of arguments. In this case the function has at least one argument. Look at the sprintf(3) man page - you'll see it there too.



Replaced these words by printf in all c codes of above tar ball


sed -i 's/err_sys/printf/g' ./*.c
sed -i 's/err_quit/printf/g' ./*.cThe functions are defined in the error.c file. The Makefile does not compile that file, but the README explains it.

From the gcc error, it would seem to me that you need to build libmisc.a.

Btw, I thought your intent was learn about socket programming. Instead, it seems your focus is to learn how to fix a "broken" package of s/w that won't compile under Linux. It's a worthy venture, but which has nothing to do with socket programming.

[gmargo]

Attached is a small patch that makes this code compile cleanly on 64-bit 10.10 Maverick. I have not tested the programs at all.

Download patch and apply to the source code directory with:


patch -p1 < ttcpcliserv_maverick.patch.txt

@gmargo
Wow your patch worked perfectly and make worked without any errors I am using 10.04 64 bit.Thanks a lot for this wonderful work.
Tell me what should I be reading if I were to be able to write patch as you wrote because there are two more zip files of the book which may also need patches in same way.

@dwhitney67
I understand your point.But the thing is I am trying to understand the example codes from the book.
Since I am a beginner so I thought that the example codes should work so that what ever I am reading I be able to appreciate that.If there is any problem in these examples I would like to fix this.

I think you might be better served with a better example.

Check out the famous beej's guide to network programming (http://beej.us/guide/bgnet/), which along with examples has enough documentation and explanation for pretty much anyone.

Yes I have read that and practiced the programs from Beej's network programming guide.Now I am trying Richard Stevens books.
