Hi Liming,
If you have a project with multiple C++ files, you can compile each
C++ file with "g++ -g" into an object file (usually with .o suffix).
Then you can link the object files together with ... "g++ -g", like
this:

g++ -g -o executable_name  a.o b.o ...

Then you have an executable with debug info, which you can load with gdb.

If you used Windows IDEs, GDB needs time to get used to. It has an
extensive manual (search for "Debugging with GDB").

There are many GDB front-ends. I've been using ddd successfully. It
has a Cygwin package, I think (under Devel).

Emacs has gdb integration. It is a very powerful editor, but takes a
long time to learn.

Anther possibility is Eclipse (it has GDB integration too, but a bit
of an overkill, really). But it's fiddly to set up because it is a
Windows program and sometimes paths have to be translated between
Windows format and Cygwin.

Hope this helps,
Csaba
