Linking error in the Application
Message 1 in thread
Hi All,
I am using qt-2.3.10 and qtopia-2.1.1.
In my application after make it is giving following linker error message.
.obj/release-shared/Main_ProcessingImpl.o:(.bss+0x20): multiple
definition of `tm_oldtime'
.obj/release-shared/drawgraphs.o:(.bss+0x0): first defined here
.obj/release-shared/Main_ProcessingImpl.o:(.bss+0x60): multiple
definition of `tm_newtime'
.obj/release-shared/drawgraphs.o:(.bss+0x40): first defined here
.obj/release-shared/Main_ProcessingImpl.o:(.bss+0x8c): multiple
definition of `t_oldtime'
But actually tm_oldtime is only declared in drawgraphs.h file and
used only in drawgraphs.cpp file.
I am inluding drawgraphs.h file in Main_ProcessingImpl.h file.
Similar type of error messages are fallowed.
If you have Any idea whay it is giving linking problem kindly let me know.
Thanks in advance,
Regards,
Harsha

Hi Andy,
Thanks for your reply.
In my main_processingImpl.h is like below.
#ifndef MAINPROCESSINGFORMIMPL_H
#define MAINPROCESSINGFORMIMPL_H
#include "Main_Processing.h"
#include <qevent.h>
#include <qwidget.h>
//////// all variables and function declarations here.........
#endif
And drawgraph.h is as below
#ifndef _DRAWGRAPHS_H_
#define _DRAWGRAPHS_H__
#include "math.h"
#include "ANSAlgo.h"
#include <string.h>
#include <time.h>
/****ECG Graph*****/
void DrawHGrid(float yaxis);
void DrawVGrid(float xaxis);
void DrawHLine(float yaxis);
void initializeECGgraph();
//int InitGL_ecg(GLsizei width, GLsizei height);
void DrawECG();
void maintainRRmark();
void render_ecg();
void maintainECGgraph(int ecgdata);
void ClearECG();
float ecg_y[400];
float ecg_x[400];
int rrmark[400];
int ecg_fulllength;
int ecg_countlength;
/****ANSindices Graph*****/
void render_ANSindices();
void DrawANSindices();
void initializeANSindicesgraph();
void maintainANSindices(float balIndex,float symIndex,float
paraIndex,char *sTime);
void ClearANSindices();
void initializeANSindicesgraphParam();
typedef struct
{
char sTime[10];
int grid;
}STIME;
STIME *IndexTime[2];

/****balANS Graph*****/
void initializebalANSgraph();

void ClearbalANS();
/****StaticbalANS Graph*****/
void initializeStaticbalANSgraph();

int checkTimeInterval(char *strnewtime);
void initTimeInterval();
time_t t_newtime;
time_t t_oldtime;
struct tm tm_newtime;
struct tm tm_oldtime;
#endif
In my Main_ProcessingImpl.cpp i included
#include "drawgraphs.h"
Thats all.
I called one of the function from here which is defined in drawgraphs.cpp
But it is giving linking error for all the variables which are
declared in drawgraphs.h
as mentioned in previous message.
If you have any suggestions kindly let me know.
Thanks

Harsha

Hi,
Thank to all for your replies,
I tryed by removing extra underscore and also like follows
#ifndef __DRAWGRAPHS_H__
#define __DRAWGRAPHS_H__
#endif
But No improvement.
About Namespcae usage i am sure that i am not using multiple names.
I really don't know why this problem is comming.
Any other suggestions kindly let me know.
Thanks to all once again,
Regards,
Harsha

Message 6 in thread
Hi Harsha,
You defined variables as global (not static) in your .h file. It gets
compiled into different .o files since you include your .h in
different compilation units. Now when you try to link those .o files,
the linker throws an error since there are multiple definitions of the
same global symbol.
If you don't want to share the variable, make it static in your header file.
Cheers,
Kiron.
