It looks like you may have forgotten to define (provide an
implementation for) your destructor.

Thanks,

Subject: collect2: ld returned 1 exit status

Hi, everyone:
I compiled a program and the result is:

Expr::~Expr [in-charge]()
collect2: ld returned 1 exit status

In my program, I defined the a class "Expr" and constructor "Expr"

class Expr
{
  int val1;
  int val2;
  char op;

  static int value(char c);

public:
  Expr(string const&);
  int operator () () const;
  void print(ostream& useStream) const;
  ~Expr();
};

Hi Yuen,

The problem is that you did not specify a main() function in your
program.cpp.

But, from your naming, it appears that you are attempting to make a shared
object library.  You should check the syntax for how to make a shared object
library on your platform.  You might need another switch, such as -shared
(the exact syntax can vary by platform).

HTH,

Dear All,

I tried to compile a program but I got the following error message:

/usr/lib64/gcc/x86_64-suse-linux/4.0.2/../../../../lib64/crt1.o: In function 
`_start':
../sysdeps/x86_64/elf/start.S:109: undefined reference to `main'
collect2: ld returned 1 exit status

Any advice on what might be the cause of this error is greatly appreciated.

I did the compilation on SuSE 10 Linux as follows:

g++ program.cpp -o program.so

Many thanks for your help.

Regards,
Yuen.
