Top Forums Programming C++ class definition with a member of the same class Post 302430671 by JohnGraham on Friday 18th of June 2010 09:45:19 AM

Several things about this post make me think you're asking something wrong:

  • Your "C" code includes a template. That's not C. Are you using some extension or something?
  • Your "C++" code includes "public class ..." - the public keyword is misplaced there, and should generate its own warning before the one you point out.
  • Your C++ code includes a List, not a list.


Is this really C and C++ code, respectively? Also, is the error you show the very first error the compiler generates?

You should be able to declare what you did. For example, this:

Code:
#include <list>

class Thing {
    std::list<Thing> stuff;
};

Compiles just fine for me, even with the -Wall, -Wextra and -pedantic flags.

Could you give a short (but full and compilable) example that demonstrates your problem?

SYNOPSIS
bool runkit_method_add (string $classname, string $methodname, string $args, string $code, [int $flags = RUNKIT_ACC_PUBLIC]) DESCRIPTION
Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. PARAMETERS
o $classname - The class to which this method will be added o $methodname - The name of the method to add o $args - Comma-delimited list of arguments for the newly-created method o $code - The code to be evaluated when $methodname is called o $flags - The type of method to create, can be RUNKIT_ACC_PUBLIC, RUNKIT_ACC_PROTECTED or RUNKIT_ACC_PRIVATE Note This parameter is only used as of PHP 5, because, prior to this, all methods were public.

Example #1 runkit_method_add(3) example <?php class Example { function foo() { echo "foo! "; } } // create an Example object $e = new Example(); // Add a new public method runkit_method_add( 'Example', 'add', '$num1, $num2', 'return $num1 + $num2;', RUNKIT_ACC_PUBLIC ); // add 12 + 4 echo $e->add(12, 4); ?> The above example will output: 16 SEE ALSO
