The question does not have to be directly related to Linux and any language is fair game.

I think I want to add C header files to my KDevelop project?


Im such a noob at this that im not sure if this is even the right question!! but anyway, I downloaded source code from Stevens "Unix network programming" book. I was hoping to use the soucecode examples in the book with KDevelop. But when I compile...ERRORS below happen... - - -Also below is souce m tryng to compile - - -

Here's corrected file (I removed the reference to unp.h, as I don't know that file)
Code:
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <string.h>
#include <netinet/in.h>

#define SERV_PORT 1234
#define LISTENQ 32

int
main(int argc, char **argv)
{
        int listenfd, connfd;
        pid_t childpid;
        socklen_t clilen;
        struct sockaddr_in cliaddr, servaddr;

        listenfd = socket(AF_INET, SOCK_STREAM, 0);

        memset(&servaddr,0, sizeof(servaddr));
        servaddr.sin_family = AF_INET;
        servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
        servaddr.sin_port = htons(SERV_PORT);

        bind(listenfd, (struct sockaddr *) &servaddr, sizeof(servaddr));

        listen(listenfd, LISTENQ);

        for ( ; ; ) {
                clilen = sizeof(cliaddr);
                connfd = accept(listenfd, (struct sockaddr *) &cliaddr, &clilen);

                if ( (childpid = fork()) == 0) { /* child process */
                        close(listenfd); /* close listening socket */
//                      str_echo(connfd); /* process the request */
                        exit(0);
                }
                close(connfd); /* parent closes connected socket */
        }
}
What I did:
* added system includes
* replaced bzero with memset
* changed the function names (they start from lowercase letter to make it compile with system headers)
* commented out str_echo, because I don't have a reference to it.
* defined SERV_PORT and LISTENQ (they're probably in the header file I don't have).

If you cna provide the header we might be able to make the program compile with it.

Hey thanks. I learned some stuff from from you're reply, but I'd prefer to get it to work with #include "unp.h", since theres like 100 examples in book and Im not smart enough yet to translate them like u did

Simplier than posting modified version..I just show the changes needed.

1
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:227: error: redefinition of `struct sockaddr_storage'
In file included from main.c:18:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:249:36: ../lib/addrinfo.h: No such file or directory
Why:
Code:
#ifndef HAVE_ADDRINFO_STRUCT
# include "../lib/addrinfo.h"
#endif
If you can find 'addrinfo.h' file in your system, modify the path to point to the file. If not, you may try to comment out the lines.

2
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:263: error: redefinition of `struct timespec'
Why:
Code:
#ifndef HAVE_TIMESPEC_STRUCT
struct timespec {
    time_t tv_sec; /* seconds */
    long tv_nsec; /* and nanoseconds */
};
/* $$.It timespec$$ */
/* $$.Ib tv_sec$$ */
/* $$.Ib tv_nsec$$ */
#endif
Comment it out. You have the structure (a bit different, but should work).

3
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:363: error: conflicting types for `gai_strerror'
/usr/include/netdb.h:620: error: previous declaration of `gai_strerror'
Why:
Code:
#ifndef HAVE_GETADDRINFO_PROTO
int getaddrinfo(const char *, const char *, const struct addrinfo *,
struct addrinfo **);
void freeaddrinfo(struct addrinfo *);
char *gai_strerror(int);
#endif
Comment it out. You have the functions.

4
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:367: error: conflicting types for `getnameinfo'
/usr/include/netdb.h:629: error: previous declaration of `getnameinfo'
Why:
Code:
#ifndef HAVE_GETNAMEINFO_PROTO
int getnameinfo(const SA *, socklen_t, char *, size_t, char *, size_t, int);
#endif
Comment it out.

5
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:371: error: conflicting types for `gethostname'
/usr/include/unistd.h:789: error: previous declaration of `gethostname'
Why:
Code:
#ifndef HAVE_GETHOSTNAME_PROTO
int gethostname(char *, int);
#endif
Comment it out. You have similar, with different types, but should work.

6
Code:
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.1/include/unp.h:391: error: conflicting types for `inet_aton'
/usr/include/arpa/inet.h:74: error: previous declaration of `inet_aton'
Why:
Code:
#ifndef HAVE_GETHOSTNAME_PROTO
int gethostname(char *, int);
#endif
Comment it out, you have it.

That's for now, for the code you tried to compile.

The main problem is that structures/functions that you have in the system are redefined in the code (sometimes with not the same parameters, but always very similar). It makes the compiler complain, because it doesn't know which ones to use...
