"undefined reference" Problem

[prakashs]

Hi All,
Iam using carbide.C++ Express IDE & symbian sdk 8.1a to find IMEI number for S60 series with the help of mobinfo 1.01 API. when i tried to build the application the following errors occured.

mobileinfo.in(mobileinfoEngine.o)(.text+0xa4):mobileinfoEngi: undefined reference to `CMobileInfo::NewL(void)'
mobileinfo.in(mobileinfoEngine.o)(.text+0xa4):mobileinfoEngi: relocation truncated to fit: ARM_26 CMobileInfo::NewL(void)

herewith i have also given the mmp file and cpp file.

what would be the cause for the errors?

You have not implemented the method in question.

I have same problem with completely different source:

// HelloWorld.cpp

#include "CommonFramework.h"
#include e32def.h
#include f32file.h

#include w32std.h     // RWsSession
#include apgtask.h    // TApaTask, TApaTasksList 
#include eikenv.h     // CEikonEnv::SetSystem()


// do the example 
LOCAL_C void doExampleL()
    {
_LIT(KHelloWorldText,"Killer!!\n");
console->Printf(KHelloWorldText);


// Wap Browser's constants UId
const TInt KWmlBrowserUid = 0x10008D39;
TUid id( TUid::Uid( KWmlBrowserUid ) );

TApaTaskList taskList( CEikonEnv::Static()->WsSession() );
TApaTask task = taskList.FindApp( id );
[...]

Same happens with this "variant" (I'm experimenting with TApaTaskList to write an app which kilss foreground application):

// HelloWorld.cpp

#include "CommonFramework.h"
#include e32def.h
#include f32file.h

#include w32std.h     // RWsSession
#include apgtask.h    // TApaTask, TApaTasksList 
#include eikenv.h     // CEikonEnv::SetSystem()


// do the example 
LOCAL_C void doExampleL()
    {
_LIT(KHelloWorldText,"Killer!!\n");
console->Printf(KHelloWorldText);

RWsSession iWsSession;
User::LeaveIfError(iWsSession.Connect());
CleanupClosePushL(iWsSession);

TApaTaskList list(iWsSession);

TApaTask task = list.FindByPos(0); // get fopreground app
task.KillTask(); // kill it!
[...]

I'm quite new to Symbian c++, so I need some kind of "kick-start"...

Note: why doesn't the forum allow to use "<" and ">" inside CODE tags???

[cassioli]

Ok, solved; I mispelled a couple of .LIB files:
#include <w32std.h> // RWsSession -->> ws32.lib
#include <apgtask.h> // TApaTask, TApaTasksList -->> apgrfx.lib

[cassioli]

This is the working source.
Using "0" rather than "1" kills the... filemanager you used to start HELLOWORLD.EXE ,as "0" is the current foreground application.
I guess that compiling shuch a code as a .APP rather than .EXE, I'll be able to add the app in the upper application bar of my UIQ phone; this should result in getting foreground application killed as soon as I click the icon of HELLOWORLD.APP .

I'll try...

// HelloWorld.cpp

#include "CommonFramework.h"
#include <e32def.h>
#include <f32file.h>

#include <w32std.h>     // RWsSession
#include <apgtask.h>    // TApaTask, TApaTasksList 
#include <eikenv.h>     // CEikonEnv::SetSystem()


// do the example 
LOCAL_C void doExampleL()
    {
_LIT(KHelloWorldText,"Killer!!\n");
console->Printf(KHelloWorldText);



RWsSession iWsSession;
User::LeaveIfError(iWsSession.Connect());
CleanupClosePushL(iWsSession);

TApaTaskList list(iWsSession);

TApaTask task = list.FindByPos(1); // 0 = get foreground app ; 1 = get launcher app of the .exe
task.KillTask(); // kill it!
   	
	}
