Thank you for the answers. It really is the path "/home/..." that 
confuses uncygdrive. When I open cygwin, I'm in my home dir /home/suwei, 
which is actually c:/cygwin/home/suwei, so I cd to 
/cygdrive/c/cygwin/home/suwei, although it's the same location. Then 
everything was fine running from there.

Thank you,
