Hi,
I am using kdeveloper to create a C++ project.
I have created a directory structure in it.
for eg,
test_dir :main folder
Include, Src : sub folders in test_dir
prj1, prj2: sub folders in Include ( to include .h header files)
prj1, prj2: sub folders in Src ( to include .cpp source files)
let b1.h, b2.h, b1.cpp, b2.cpp are the header and source files included in prj1, prj2, prj1, prj2 resp.
let b1.h be
----------------
#ifndef STRREV
#define STRREV
#include<iostream.h>
void strrev(char * source);
#endif
let b2.h be
-----------------
#ifndef STRLEN
#define STRLEN
#include< iostream.h>
int strlen1(char *);
#endif
let b1.cpp be
------------------
#include "/home/sheena/test_dir/test_dir/Include/prj2/b2.h" //path for include file
#include "/home/sheena/test_dir/test_dir/Include/prj1/b1.h"
void strrev(char * source)
{
int i,j;
char dest;
int n=strlen1(source);
for(i=0,j=n-1;i<j;i++,j--)
{
dest = source[i];
source[i]=source[j];
source[j]= dest;
}
source[n]='\0';
cout<<source;
}
int strlen1(char *source)
{
int n=0;
while(source[n] != '\0')
n++;
return n;
}
let b2.cpp be
------------------
#include "/home/sheena/test_dir/test_dir/abc1/a2/b2.h"
#include "/home/sheena/test_dir/test_dir/abc1/a1/b1.h"
int main()
{
int n;
char * source ="sheena";
strrev(source);
n= strlen1(source);
cout<<"\n length is "<<n<<endl;
return 0;
}
------------------------------------------------------------------------------------
All my files b1.cpp and b2.cpp are compiling successfully, but during executing this small program i am getting some linking error like follow:
