Hi,

Do anybody have trouble linking C++ program that uses the C++ exception 
mechanism? The following program won't link and the linker produces the
theses error messages:
	undefined reference to terminate(void);
	undefined reference to unexpected(void);

// this prog was taken from C++ FAQ book 

#include <iostream.h>

void fred() throw(const char*)
{
	cout << "fred() throwing\n"; throw "barney"; 
}

class X {
public:
  ~X() throw();
};

X::~X() throw()
{
  try {
    fred();
  }
  catch (const char *msg) {
    cout << "handling fred()'s exception: " << msg << '\n';
 }
}

int main()
{
  try {
   X x;
   cout << "main() throwing\n";
   throw "main";
  }
  catch (const char* msg) {
   cout << "handling main()'s exception: " << msg << '\n';
  }
  return 0;
}

here is the command line that I use:  gcc -fhandle-exceptions t.cc -lgpp
