header file/class problems
Hi,
I recently wrote a small morse code converter and then decided to combine it with the network programming stuff I'm learning and then decided to mash that up in turn with some OO programming which I am also learning and it would all run in linux. Not that I'm trying to overload myself or anything :P Anyways, I wrote a class, which is shown below, along with a few member functions which facilitate my server/client communication and stuck it all in a header file. Problem is the compiler always complains that it can't find the header file. I tried putting the header file in the compiler's search path, changing the suffix from '.h' to '.hpp' (which it should have been in the first place right?) and tried enclosing it in quotes i.e (#include<"morse.hpp">) alas nothing works. So I checked google but the various tutorials I read didn't mention anything I could see as protentially causing my problem. As far as I can tell I am doing everything right, but this is the first time I am using header files, and OOP so I guess I can blame that :P.
It probably doesn't help that I am trying to compile this on linux live cds and on NetBSD running on a sparc64 processor lol but it should work right?
Anyway here are the errors and code:
Quote:
-bash-2.05b$ g++ morse_serv.cpp -o morse.serv

Now I'm concentrating on the class and header file releated errors as I am pretty sure I have had the others before and they are fairly easy to fix. Btw, this is the output from g++ on netbsd^^.
Code:

#include<cstdlib>

I have included those header files as the compiler complained otherwise.
Code:
#include<iostream>
#include<sys/types.h>
#include<sys/socket.h>
#include<"morse.hpp">
#include<netinet/in.h>
#include<arpa/inet.h>
#define CLIENT_QUEUE_SIZE 2
#define MAX_DATA 1024
using namespace std;
int main(int argc, char *argv[])
{
if ( argc == 3 )
{
cout<<"USAGE: ./morse_list [PORT NUMBER]\n";
exit(-1);
}
int sock, cli_sock;
char *greeting = "Connected to the server.\n";
char input[MAX_DATA];
int len = strlen(greeting);
int recv_len;
struct sockaddr_in serv;
struct sockaddr_in client;
morse m;
serv.sin_family = AF_INET;
serv.sin_port = htons(argv[1]);
serv.sin_addr.s_addr = INADDR_ANY;
memset(serv.sin_zero, '\0', sizeof(serv.sin_zero));
if ((sock = socket( PF_INET, SOCK_STREAM, 0 )) == -1 )
{
cout<<"Could not open socket.\n";
exit(-1);
}
if ((bind( sock, ( struct sockaddr *)&serv, sizeof(serv))) == -1 )
{
cout<<"Could not bind socket.\n";
exit(-1);
}
if ((listen( sock, CLIENT_QUEUE_SIZE )) == -1 )
{
cout<<"Could not listenon the network.\n";
exit(-1);
}
cli_sock = accept( sock, (struct sockaddr *)&client, sizeof(client));
if ( cli_sock == -1 )
{
cout<<"Could not accept connection.\n";
exit(-1);
}
cout<<"Connection on port "<<ntohs(client.sin_port)<<"from "<<inet_ntoa(client.sin_addr.s_addr)<<"\n";
int bytes_sent = send( cli_sock, greeting, len, 0 );
if ( bytes_sent == -1 )
{
cout<<"FAIL: Could not send greeting\n";
}
while(1)
{
memset(input, '\0', MAX_DATA);
if ( (recv( cli_sock, input, MAX_DATA, 0 )) == -1 )
{
cout<<"Failed to receive data.\n";
exit(-1);
}
recv_len=strlen(input);
if ( input[0] == '\0' )
{
cout<<"Empty packet received, waiting for next useful packet...";
}
else
{
m.mtob(input[]);
}
}
close(cli_sock);
cout<<"Client connection terminated.\n";
close(sock);
}
