Tool to visualise code flow (C/C++) [closed]

Answer 1

Doxygen is very good at generating diagrams from code without applying markup, if you turn on the EXTRACT_ALL option. You need GraphViz installed to get diagrams generated with the HAVE_DOT setting. I find having it installed and leaving the DOT_PATH blank works fine on Windows but on OS/X keep having to point directly to the dot tool location.

There's an excellent Code Spelunking article in ACM Queue which talks more about using doxygen and DTrace.

Answer 2

i tried a tool named Visustin which is not very great graphically but does what it says: Flowchart from Code. http://www.aivosto.com/visustin.html

Answer 3

SourceInsight and Understand for C++ are the best tools you can get for c/c++ code analysis including flow charts.

Answer 4

There's also AspectBrowser which doesn't work very good with Eclipse 3.4.0

Answer 5

There are some tools like Egypt http://www.gson.org/egypt/egypt.html that work, but only if you match the expected GCC version used to compile the code and the exact version of the callgraph generator. The same can be said about codeviz http://www.csn.ul.ie/~mel/projects/codeviz/

Other option is valgrind used in cachegrind mode (it generates a type of callgraph that you can follow from kcachegrind program.

Answer 6

Doxygen will give you class relationship diagrams if you use graphviz, even if you haven't specifically prepared for it.
