undefined reference to 'abc::abc()' with Dwarf Error: Offset appearing

I declare an obj :

#include "abc.h"

class xxx
{
public: 
  xxx();
  ~xxx();
  abc* q;
...
};

in the .cpp file i do the following

this->q=new abc(); <-error on this line with undefined reference to abc::abc()

In the console it also appears this error:

Dwarf Error: Offset (76195) greater than or equal to .debug_str size (1472).

anyone knows what could be wrong? i'm using eclipse, fedora 14

It looks like the implementation of the abc class is not included in the build. Add the abc.cpp file to the build.

this->q=new abc(); <-error on this line with undefined reference to abc::abc()

From your error it seems that you have only the declaration of abc::abc() and there is no definition present. Define abc::abc() in source file or make it inline in header file.

undefined reference to abc::abc()

It is an Linking error which tells you that the linker could not find the definition for abc::abc().

Most likely, You only declared but did not define the no argument constructor for class abc.
In your cpp file you should have: 

abc::abc()
{

}

If you already have it in place then, You should ensure that the source cpp file which has this definition is being properly linked to your project.
