Alright, I can compile the code using MSVC 8. Cool now I can start toying with it!
I seem to avoid the error but run into an ICE in the storage component (timed_generator inherits storage). If I throw out timed_storage and just feed proc with values manually, I get errors regarding traits_of. That I might be able to deal with in time - I would conjecture that for 7.1, the basic Dataflow.Signals layer might be doable but the generic components might be really tricky to get to work.
At the risk of talking out of my ... . A library to review would at the very least need to compile with MSVC 7.1. I deal with the same problem right now. Code works for MSVC 8 but trying to make it compile with MSVC 7.1 is a pain. Also, my code looks good in a sense that I wouldn't like it to mess it up with preprocessor stuff or boost/config. Do you think you can rewrite the layer again to have a work with 7.1? Christian
