okay, I keep getting this compiler error message:
Undefined. . . . . . . . . . . . . . . . . first referenced

rob::Book::~Book() . . . . . . . . . . . /var/tmp//ccZWEnnc.o

ld: fatal: Symbol referencing errors. No output written to a.out
collect 2: ld returned 1 exit status
rob::Book::~Book() <===this is the destructor for class Book in namespace rob that I created, the other one is the default constructor. I've tried everything I can think of and more. I need some serious help, I still have a lot left to work on for this project lol
if you see anything that could be wrong please help. I had it working fine as one file, but when I split it up it stopped workingCode://class header file #include <string> #include <cstdlib> using namespace std; namespace rob { class Book { public: ~Book(); Book (const Book& b1); void operator =(const Book& b1); Book(); void print (ostream& outs); void fill (istream& ins); private: string* title; string* author; int copies, dollars, cents; }; } //implementation file. I'll only put the destructor and default //constructor because those are the problem ones #include <iostream> #include <cstdlib> #include <string> #include <fstream> #include <cctype> #include "book.h" //header file using namespace std; using namespace rob; namespace rob { Book::~Book() { delete title; delete author; } Book::Book() { title = new string; author = new string; copies = 0; dollars = 0; cents = 0; } //etc etc etc, the rest works fine } //main program, just testing to see if it compiles (which it doesn't) #include "book.h" using namespace std; using namespace rob; int main() { Book b1; return 0; }
