Reverse Engineering C code [message #154647]

Hi all

I am working on embedded technology and we have "huge" legacy code written
in native (ANSI C) language waiting to be reverse engineered to UML
format.
We have also developed a parser (RE tool) which does so, but it is not
100% proven; it does not check all dependencies and macros between classes
(UML Class name = C file name, methods in that file or UML class given
prefixes to identify dependencies between classes).
Question : Is there any tool in market (free or not) to do such kind of
reverse engineering? Also, is there any plugin for Eclipse to do the
same?(I have downloaded CDT and it seems working fine). Moreover, we need
to auto-generate documents based on the extracted UML architecture.

Many thanks for any sort of help!

Rgds,
Pranay

Hi!

The only workchain I know is: MS Visual Studio (compiling + generating a
browse
information file) and passing this file to MS Visio which generates a
class diagram.
Unfortunately, these programs are not free and do not work within eclipse.
Additionally,
some class attributes are missing their type definition if they are
standard c++ types
like double or int.

Hopes this helps
andrés

Thanks Andrés, we have an old version of Visio and this thing seems not
possible as I am not sure if it will show Packages also. As we wrote C
code as per UML notation or in more "object" sence, it seems difficult.
The main objective is also to update an existing UML diagram (Rose) with
respect to changes made in the code (files) over the upgrade versions.
Subsiquentely, the aim is to have coherence between the UML and code and
to generate document using UML.

Anybody for other ideas ?? !!
