Without seeing the full set of your source code and how you're
including files and whatnot, it's impossible to say for sure. An
educated guess is that your typedef for Kstruct is somehow not
appearing before you try to instantiate masterKstruct, or, similar to
your previous problem, perhaps you've got executable C code before your
instantiations, which is forbidden in C.
Based on your later errors regarding baseaddress, I'm guessing it's the
latter -- so none of your variables are being instantiated, and
therefore become "undeclared" later in the function. But again -- it's
hard (impossible) to say for sure by only looking at a snipit of your
code.
That being said, these look like basic C compilation issues, not really
having to do with LAM, MPI, or parallel computing. Forgive me for
being blunt, but this is not really within the scope of this mailing
list. I would strongly prefer if we kept on-topic -- discussing LAM
and/or MPI issues, not generic C compilation problems that are
unrelated to parallel programming. You might want to consult a C
reference book or have a chat with some local C programming wizards.
Thanks!
