Hi there, I'm pretty new to spirit and I need a semantic action to construct an object (that's fine) using a vector<double>, the vector is the problem. I'd really appreciate help with this error, or perhaps I'm not using the right technique, in which case, I'd need suggestions on how to proceed.
Even if I don't use it anywhere, just adding the following to my grammar base class template parameter and adding the same to the rule declaration I need it for, it gives the monster error below.

Hi Simon - It will be easier to help if you have a minimal example of what you are trying to do. qi::locals are typically used when needing to store and pass state within grammars (rules). If you are trying to "return" a value from a parser, that is called synthesis and you can use compatible attributes to do that. Perhaps a description of what you are solving and your rule(s) might allow us to provide better information. michael -- Michael Caisse ciere consulting ciere.com
