Hi
I have two files calc.cpp and calc.h
in file calc.h class Offsets is declared

class Offsets : public Worksheet {
public:
double GetPeak( int i ) ;
} ;

in file calc.cpp body of GetPeak is defined

double Offsets::GetPeak( int i )
{
return Cell( i, 3 ) ;
}

in other file I call function GetPeak

Offsets off ;
double a = off.GetPeak( 1 ) ;

On linking I get error
"
Function ... was called, but its body could not be located during linking.
"

But if I define function body in class declaration
class Offsets : public Worksheet {
public:
double GetPeak( int i )
{
return Cell( i, 3 ) ;
}
} ;

all is ok

What is problem?
Can I defined body of class function in file different one where class is declared?

Hello alcrux,

Please be reminded that calc.cpp must be compiled when you call GetPeak in another place.
