Then I think the only solution is that you allow compiled plugins .dll/.so in your project. And the "user" is a just developer that build the plugin and copy it in your application folder. -----Messaggio originale----- Da: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] Per conto di Isaac Lascasas Inviato: domenica 17 agosto 2008 19.03 A: boost-users@lists.boost.org Oggetto: Re: [Boost-users] building and calling "dynamic c++" from ahostprogram Thanks for your proposal, I have not yet tested any c++ interpreter and I don't know how fast these tools can execute the client code. It can be a good alternative but I think it should exist a better alternative for certain situations. I'm more interested in fast execution of the embedded code than in instant interpretation so the build time is not a problem. My objective is to write a fast real time graphic effects prototyping tool and let the user eventually write chunks of code in c++, for example to process a list of thousands of items for a particle system as fast as if I rebuild the whole thing with the new user code. In other words, the main problem I have is that time-critical code can be placed inside this dynamic c++. Regards, Isaac Lascasas.
