Hi Manuel, Sorry for the long delay - I am away at a conference and with very intermittent internet access. On Tue, Sep 16, 2008 at 1:26 PM, Manuel Jung <gzahl@arcor.de> wrote:

Hey Stepjan,

I'm developing a new component, a multichain, which should be able to chain different components together. Well the fusion and mpl libraries are somewhat new to me, but here ist my approach. I have some problems:

This is a nice idea.

When the MultiChain Component is constructed, nothing seems to get constructed, nor connected. Not even the constructors are being called?

I only had time to take a brief look. I think something with the iterator initialization might be wrong, but I'm not sure (I haven't used fusion iterators directly before). E.g., you have: typedef typename boost::fusion::result_of::prior<last>::type before_last; vec_T components; and then: before_last Before_Last(components); should that be: before_last Before_Last(prior(last(components))); ? Again, not sure - sorry if this is no help at all, I will take a better look when I get a chance. Stjepan
