Hi Yaakov
Thanks for your reply.
This has helped me a little but I am grateful for a bit more help please.
As I have already downloaded Cygwins GtK+ packages do I not already have gtkmm 
installed in cygwin?
I tried to follow instructions to get Cygwin-built GTKmm from Cygwin-Ports but 
when I looked at the Cygwin-Ports available packages these are:
gtk-vnc                                            0.3.10-1
gtk1.2-engines                                     0.12-10
gtk2.0-canberra-module                             0.22-1
gtk2.0-engines-qt4                                 1.1-10
gtk2.0-engines-qtcurve                             1.0.1-1
gtk2.0-engines-xfce                                2.6.0-10

with no sign of GTKmm (?)
I apologise if I am missing something here (I am only an amateur programmer 
but I would like to compile gtk+ code in cygwin and in cmd prompt in Vista and 
am finding this hard to acheive!).
I didn't really understand how to use cygwin download with the -X flag either?

Most grateful for more of your fine advice and help, many thanks
Richard
