Nice! const_mem_fun worked in this sample. I will try to port my map to multi_index now and see how it performs.
But, I dont want to give up without understund why mem_fun doesnt work. Anybody has any theory? :D
Thanks Jeff.

Well, I still having trouble to get mem_fun working. multi_index accept
boost mem_fn?
Joaquin, the const still wont work. I stripped down the sample to this code:
[code]
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/mem_fun.hpp>
#include <boost/multi_index/ordered_index.hpp>
using boost::multi_index_container;
using namespace ::boost::multi_index;
class Entry
{
private:
int size;
public:
Entry(int s) : size(s) {}
int getSize() const { return size; }
};
typedef multi_index_container<
Entry,
indexed_by<
ordered_non_unique<BOOST_MULTI_INDEX_MEM_FUN(Entry,
int, getSize) > // line 23
Doesn't this work?
ordered_non_unique< const_mem_fun<Entry,int,&Entry::getSize>
>
>
> EntryCollection;
void main() {
EntryCollection entries;
Entry a(3);
entries.insert(a); // line 33
}
