Hi,
I have a problem with a hash-index to a member of type
std::vectorstd::strings. With boost 1.34 it compiles
and runs find, but it fails to compile with 1.33!
Unfortunately I do not have the luxury to change
boost-version. Is there any way around this?
I defined my multi_index_container like this:
typedef std::vectorstd::string keys_type;
struct entry_type
{
keys_type keys;
bool operator<(const entry_type& e) const
{ ... }
};
typedef boost::multi_index::multi_index_container<
entry_type,
mi::indexed_by<
mi::hashed_unique<
mi::tag,
mi::member >,
mi::ordered_non_unique<
mi::tag,
mi::identity >
mi_entries_type;
And get the following compile-error (see the bottom):
/usr/bin/g++ -m64 -pipe -Wall -fPIC -O3 -DNDEBUG
