Emacs is an environment which builds upon the generic concept of text buffer. This is a very powerful concept, because it allows for rich tool support, and for in-depth and relatively light-weight user configuration. By comparison, windows offer little support and a high threshold for users to produce useful tools. Humans painted on cave walls 3 years ago. Then they invented language. GUIs have so far proven a temporary re-play of history for people who didn't record it.

Re: Questions about gnu debug
And this may add a little to your understanding: gdb is a reasonable debugging tool, but is *command line* oriented. By itself, it provides no GUI interface. If you compile with -g then the available symbols let you talk about (non-local) variables, code locations, etc. emacs is an *editor* that can provide a somewhat GUI-like interface to gdb, by interpreting line numbers coming from gdb and positioning an editor cursor on the indicated line (good for stepping, etc.). And so forth. That is, emacs and gdb can play together reasonably well, but it would probably still feel somewhat primitive compared to advanced GUI interfaces. Eclipse can provide a good GUI interface, perhaps not quite as well integrated for C/C++ as for Java, but I understand it is pretty good. As stated before, it might be a little finicky to set up. Again, I believe it is calling gdb underneath. Hope these distinctions help.Eliot Moss -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

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.

Questions about gnu debug
I read the FAQ, but still very confused, please help. 1. I have a project written by C++, I want to debug it under Cygwin. I know I can use g++ -g, but I think this is for a single .cpp file. How to debug a whole Project? Anyway to debug the project inside a windows like editor? 2. The gnu C++ under Cygwin only support 32 bit windowss vista or 7. Is that right?
