Charm++ parallel programming system

[Fernando Stump <fernando.stump AT gmail.com>]

Hi,

I realized that this error come from the fact that I'm trying to compile a 
pure c++ code as if it was charm++ (i.e. without the .ci)

My final goal is to use ParUFM, so I need to create the init() and driver() 
function. For now I would like to compile my code such that it starts form 
the main on my C file

The question is: Which language should i set on charmc, such that it compile 
and link a plain c++ code.

Thanks
Fernando
