questionsolved  Weird syntax error

JRevor (119)   Link to this post
My lecturer wrote this code

class IOBuffer {
  public:
    virtual TPointer Read(fstream& fs) = 0;
};


Error `Read' declared as a `virtual' field. Expected `;' before '(' token, expected unqualified-id before '=' token .

What is going on here?

It should work, do you have some other code with that?

This is just a portion of the code. The code itself is way bigger.
TPointer was declared already in the beginning

typedef long TPointer;
typedef int TSize;
const int MAXBYTES = 1000;
const long PNULL = -1;

Found the error. The code was missing this line
  
using namespace std;

I tried that in g++ 4.4 but it doesn't complain.
Which compiler / options are you using?
Do you get other error messages?
