Just curious, is there a difference between 'command based' C++ and 'standard' C++? Is there such a thing as non-command based C++?
Anyway, we have C++ running on our robot. I think something similar happened with us; I can't recall completely since it was so long ago. I downloaded windriver and installed all the updates--but the updates weren't the correct version. (And we had a host of other problems with other C++ related things, such as the imaging tool not working on our crio--all which are fixed), but my advice would be to double check that you have the latest (2012) versions of everything. FRC2012UtilitiesUpdate2.0.zip would help (a simple google search should reveal the download link).
EDIT: Disregard everything I said. I don't want to delete this post, but to the people who come across this thread on Google and want to know about command based C++, here you go:
