Re: [Boost-users] building and calling "dynamic c++" from a hostprogram

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.
