Are there any non-commercial, open source C or C++ tools to reverse engineer C or C++ programs with source codes on linux? i.e. It parses any sized C or C++ project to help reverse engineer, document, draw UML diagram and understand it and thus maintain it better.

As a free tool, try doxygen ([url]www.doxygen.com)[/url]. It can generate hyperlinked HTML from source code, class hierarchy graphs, called-by lists, and more... hth, Ivan -- http://ivan.vecerina.com/contact/?subject=NG_POST <- e-mail contact form Back to top E.

No. There is no tool that can make sense out of nonsense. There are programs like Doxygen http://www.doxygen.org/ that will automatically create documentation from comments embedded in your source code so that you can maintain your code an documentation together.

There are programs like Doxygen http://www.doxygen.org/ that will automatically create documentation from comments embedded in your source code so that you can maintain your code an documentation together. Just because this is easily misunderstood, I would like to insist that doxygen can generate a lot of useful information, also from code that does not contain any (doxygen) comments. The output can still include: - hyperlinked source code (click an identifier -> shows its definition) - header dependencies (includes & included-by graphs) - function call dependencies (links to all calls to a function) - class hierarchies (graphs, links) - index of namespaces, class names, etc... There are IDEs that can provide some of the navigation interactively. Nevertheless, doxygen generates valuable information (and even more once you use doxygen-specific comments), expecially when reviewing the structure of a program.

Some compilers have pretty good class browsers that will help. I'm not sure about their ability to format the output for printers...you'd have to check. But CodeWarrior (which I use) does a pretty good class tree diagram. Rational Rose will do the job of creating UML from source, I think. (But it's insanely expensive!) Just a little (nit-picky) side note: source code doesn't require "reverse engineering", since it's already source code. That term usually means taking raw machine code and creating some form of assembler or source code from it. -Howard Back to top olivier Guest Posted: Tue Jan 18, 2005 2:31 pm    Post subject: Re: understand source code of a C++ program written by someo "Ivan Vecerina" <INVALID_use_webform_instead (AT) vecerina (DOT) com> wrote what about umbrello ?

Found here: http://uml.sourceforge.net I had never tried it. It looks like a nice UML modeler and code generator. Thanks, I will look into it. However, the original question was about extracting design information from existing source code. Umbrello does not seem to have that capability.
