RedHat 6 – Porting code to RH6

We are moving our product’s OS from RedHat 5 to 6, as well as new version of ‘gcc’ (4.X) along with RH6.  To port the existing code to RH6 with new compiler, there might be a lot of things we need to care. This post gives a brief summary for the issue during our trial and hopefully would be updated timely. May it help:)

1. C++ header file include
#include <iostream.h> -> #include <iostream>
#include <typeinfo.h> -> #include <typeinfo>
#include <list.h> -> #include <list>
#include “poll.h” -> #include <poll.h>
#include “fcntl.h” -> #include <fcntl.h>
a. All the standard C++ header file need to omit “.h”;
b. Standard C header file could have both format:
        #include <stdio.h> OR
        #include <cstdio>
   NOT  #include “stdio.h”

2. SCTP library
libsctp.a -> -lsctp
RH 6 does not support static lib of SCTP. Should be dynamically linked.

3. SCTP struct/API
sctp_adaption_layer_event -> sctp_adaptation_layer_event
SCTP_ADAPTION_INDICATION -> SCTP_ADAPTATION_INDICATION
sctp_connectx(int, sockaddr*, int) -> sctp_connectx(int, sockaddr*, int, sctp_assoc_t*)
a. Member name updated in structure sctp_event_subscribe
b. Member name updated in enum sctp_sn_type
c. New argument updated in function sctp_connectx

4. Linux Kernel API
extern struct net_device *dev_get_by_name( const char *name) ->
extern struct net_devide *dev_get_by_name( struct net *net, const char *name)
