View Full Version : latest svn update errors in iOS

04-04-2012, 09:06 AM

Latest svn update introduces errors in function GetMacAddress() in iOSUtils.mm
Exactly the errors are:
if ((mgmtInfoBase[5] = if_nametoindex("en0")) == 0) --> Use of undeclared if_nametoindex
socketStruct = (struct sockaddr_dl *) (interfaceMsgStruct + 1); --> Arithmetic on a pointer to an incomplete type
memcpy(&macAddress, socketStruct->sdl_data + socketStruct->sdl_nlen, 6); --> Member access into incomplete type

Only if you does not noticed it yet.

Hmm, strange, I am not getting those errors. Can you make sure you have these includes near the top of iOSUtils.mm?

#include <netinet/in.h>
#include <net/if.h>
#include <net/if_dl.h>

I am using Xcode 4.2, what are you using?

I am using Xcode 4.3.2

The top of my iOSUtils.mm

#include "iOSUtils.h"
#import <UIKit/UIKit.h>
#import <cstdarg>
#include <string>
#include <sys/time.h>
#include <sys/sysctl.h>
#include "BaseApp.h"
#include <SystemConfiguration/SystemConfiguration.h>
#include "Network/NetUtils.h"
#import <MobileCoreServices/MobileCoreServices.h>
#import <MyAppDelegate.h>
#import <EAGLView.h>

using namespace std;

void LogMsg(const char *lpFormat, ...)

I just copy those includes to the iOSUtils.mm file and compiled fine.

Hmm, those lines are definitely in the latest svn version.. not sure why it isn't getting picked up by your svn update.

You can see the svn version here (http://rtsoft.com/svn/filedetails.php?repname=Proton&path=%2Fshared%2FiOS%2FiOSUtils.mm).

Sorry for late reply.
I have just made a svn update and get rev. 876.
I am using MacOS X 10.7.3 Lion with svn version 1.6.17 that is preinstaled with the system.
I don't understand why doesn't get the iOSUtils.mm correctly.
Anyway, it's working right now, so don't worry :cool:
