Summary

0000059: Imcomplete implementation of member binding for list algorithm

Description

The following sample code will generate some errors:

/root/uClibc++-0.1.9/include/functional: In member function `bool
   std::unary_negate<Predicate>::operator()(typename Predicate::argument_type&)

   const [with Predicate = std::mem_fun_t<bool, const x>]':
/root/uClibc++-0.1.9/include/algorithm:52: instantiated from `InputIterator st
d::find_if(InputIterator, InputIterator, Predicate) [with InputIterator = std::l
ist<x*, std::allocator<x*> >::iter_list, Predicate = std::unary_negate<std::mem_
fun_t<bool, const x> >]'
z.cpp:26: instantiated from here
/root/uClibc++-0.1.9/include/functional:179: error: passing `const
   std::mem_fun_t<bool, const x>' as `this' argument of `S std::mem_fun_t<S,
   T>::operator()(T*) [with S = bool, T = const x]' discards qualifiers

---- The sample ----
#include <algorithm>
#include <list>
#include <map>

using namespace std;

class x {

public:
    x(int _i = 0): i(_i) {}
    x(const x& _x): i(_x.i) {}
    bool good(void) const { return true; }

private:
    int i;
};

typedef list<x *> list_t;

main()
{
    list_t l;
    list_t::const_iterator p;
    bool ok;

    if ((p = find_if(l.begin(), l.end(), not1(mem_fun(&x::good)))) != l.end()) {
        ok = true;
    }
}

---- The sample ----

Notes
(0000025) gkajmowi 01-24-05 20:31	This has been fixed in CVS. This is due to a lack of a const identifier on an operator. Fill will be in >=0.1.10
