Curious Error I Cannot Figure Out (templates)

[mieskola]

Below, I posted the error, the function call that generated the error,
and the function itself. I have been spinning my wheels trying to
figure this out. The source files compile, just generating a test
executable fails. This code works on on a Digital UNIX machine, but
fails while I am trying to port to Linux.

Thanks.



ERROR:
------------

someFile.C:83: undefined reference to `MsgRouter<int,

::Register(int const&, MsgHandler<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >*)'

CALLING POINT:
------------------------

someFile.C -> LINE 82: MsgCatcher lCatcher;
someFile.C -> LINE 83: msgRouter.Register(1, &lCatcher);

where MsgCatcher is defined as: class MsgCatcher : public
MsgHandler<string> {..}


FUNCTION:
-----------------

template<class KeyType, class MsgType>
void MsgRouter<KeyType, MsgType>::
Register(const KeyType &ipKey, MsgHandler<MsgType> *ipHandler)
{
// some code here ...
}

Please try to reduce your code to a minimal but complete sample that
generates the error and that we can cut-and-paste *unedited* into our
editors. See the posting guidelines for code here:
