Question

I get these errors messages all over the place for g++ 4.1.2, and it doesn’t help at all:

<file>:<line>: error: expected primary-expression before 'int'
<file>:<line>: error: expected ';' before 'int'
<file>:<line>: error: invalid use of qualified-name '::SuccessCode'

The piece of code where it happens is as simple as this:

class Test
{
  static Status debug_function(void)
  {
    return Status::SuccessCode();   // this would be <file>:<line> mentioned above
    // and this one too:
    // return Status::FailureCode("test");
  }
};

And here’s the code for Status (and yes it’s properly included, because I would have an error if the include file was invalid):

namespace CODES
{
  enum Values { Success = 0, Failed = 1 };
}

class Status
{
private:
  CODES::Values code;
  string msg;
public:
  Status(CODES::Values val, const string &i_msg ): code(val), msg(i_msg) {}

  static Status SuccessCode(void)
  {
    return Status(CODES::Success, "");
  }

  static Status FailureCode(const string &fail_msg)
  {
    return Status(CODES::Failed, fail_msg);
  }
};

So, what is wrong with this piece of code ? And it compiles properly under VC++!

EDIT: Actually, the code for SuccessCode and FailureCode are in a *.cpp file. I put them in the class declaration because the error message is still the same!

Without a complete program, I’ll have to guess. My guess is: you have a #define Status int somewhere in your program.
