Re: [ES40-developers] ES40 Emulator Status Update

[Fausto S. <fa...@un...>]

Hello Camiel,

this is very interesting news...
Just a question about POCO libraries: which one we have to compile?  
the light version, or the enterprise?
I'm trying to compile and install the light one, but I have a problem  
because the visual studio file looks for "mc" command.

What's that command?
Do you have the same problem?

regards,
fausto
