Re: [sigc] <lambda/group.h> problem solved

It seems that gcc 3.4.2 wants this line of code:

{ typedef typename functor_type::deduce_result_type<

at lines 79, 245 and 458 in <lambda/group.h> declared like this:

{ typedef typename sigc::adaptor_trait<T_functor,
sigc::is_base_and_derived<sigc::adaptor_base,T_functor>::value>::adaptor_type::template 
deduce_result_type<

After making the changes it compiled OK.

Hi,

I've attached the adaptors/lambda/group.h file with the changes, so you
can see if I made mistakes....

A very big thank !

P.S.
my gcc version is 3.3.4:

/** @defgroup group_ group()
 * sigc::group() alters an arbitrary functor by rebuilding its arguments from one or more lambda expressions.
 * For each parameter that should be passed to the wrapped functor one lambda expression
 * has to be passed into group(). Lambda selectors can be used as placeholders for the
 * arguments passed into the new functor. Arguments that don't have a placeholder in one
 * of the lambda expressions are dropped.
 *
 * @par Examples:
 *   @code
 *   void foo(int, int);
 *   int bar(int);
 *   // argument binding ...
 *   sigc::group(&foo,10,sigc::_1)(20); //fixes the first argument and calls foo(10,20)
 *   sigc::group(&foo,sigc::_1,30)(40); //fixes the second argument and calls foo(40,30)
 *   // argument reordering ...
 *   sigc::group(&foo,sigc::_2,sigc::_1)(1,2); //calls foo(2,1)
 *   // argument hiding ...
 *   sigc::group(&foo,sigc::_1,sigc::_2)(1,2,3); //calls foo(1,2)
 *   // functor composition ...
 *   sigc::group(&foo,sigc::_1,sigc::group(&bar,sigc::_2))(1,2); //calls foo(1,bar(2))
 *   // algebraic expressions ...
 *   sigc::group(&foo,sigc::_1*sigc::_2,sigc::_1/sigc::_2)(6,3); //calls foo(6*3,6/3)
 *   @endcode
 *
 * The functor sigc::group() returns can be passed into
 * sigc::signal::connect() directly.
 *
 * @par Example:
 *   @code
 *   sigc::signal<void,int,int> some_signal;
 *   void foo(int);
 *   some_signal.connect(sigc::group(&foo,sigc::_2));
 *   @endcode
 *
 * Like in sigc::bind() you can bind references to functors by passing the objects
 * through the sigc::ref() helper function.
 *
 * @par Example:
 *   @code
 *   int some_int;
 *   sigc::signal<void> some_signal;
 *   void foo(int&);
 *   some_signal.connect(sigc::group(&foo,sigc::ref(some_int)));
 *   @endcode
 *
 * If you bind an object of a sigc::trackable derived type to a functor
 * by reference, a slot assigned to the group adaptor is cleared automatically
 * when the object goes out of scope.
 *
 * @par Example:
 *   @code
 *   struct bar : public sigc::trackable {} some_bar;
 *   sigc::signal<void> some_signal;
 *   void foo(bar&);
 *   some_signal.connect(sigc::group(&foo,sigc::ref(some_bar)));
 *     // disconnected automatically if some_bar goes out of scope
 *   @endcode
 *
