Editing .cc files?

Hi,
i am using the ubuntu 9.04 and installed the gnuradio at the build guide
through the binary package instructions for ubuntu at:

http://gnuradio.org/redmine/wiki/gnuradio/DebianPackages

i placed a problem here a couple of days ago and the solution suggested
that
i should modify c code written in the file “gr_quadrature_demod_cf.cc”
in
order to get the desired results. the problem is that i am unable to
locate
the .cc files.

You have to download and build from source to be able to modify the .cc-
files.
