OK, I’m recoding for the string solution now – thanks for the tip.

Best wishes.

Subject: Re: [Boost-users] Using boost::uuids::uuid as a map index

Hi,

All look-ups within the map based on the UUID then fail, as adding the
object to the map is essentially a copy operation and UUID is non-copyable,
so new unique identifiers were generated.  I then tried:

Std::map <boost::uuids::uuid *, myClass*> myMap;

AFAIK uuid is copyable as it's a POD.

However, I don't know about this problem but I remember having failed to make uuid a key of map (I don't remember the reason).

If that can help you, I'm using a workaround to allow this : I convert the uuid to std::string (using the generator function) and use it in my whole application to allow finding by uuid from maps. That's obviously more expensive but it works fine.
