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. > How > to debug a whole Project?

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.
