I am impressed by Schaub's answer, using Clang I would expect Clang to have all the elements right. I don't know what they use for a parser, or whether they do the detailed analysis right I have no specific experience with their product. Such profilers will show you the actual call graph exercised.ĮDIT: I suddenly remembered Understand for C++, which claims to construct call graphs. You might be better off running a timing profiler which collects a call graph dynamically (this describes ours) and simply exercise a lot of cases. Doxygen doesn't have any of these, I don't know why people claim to like it for C++ it is easy to construct a 10 line C++ example that Doxygen erroneously analyzes). Statically computing an accurate C++ call graph is hard, because you need a precise langauge parser, correct name lookup, and a good points-to analyzer that honors the language semantics properly.

I did not manage to install it myself and that's why I tried to find an alternative solution! SOLUTION 3 : With Johannes Schaub - litb main.cpp, it generates this:ĭoxygen/dot are probably easier than clang/opt to install and run. You can achieve that by using doxygen (with option to use dot for graphs generation). That mystical unnamed function, Node0x884c4e0, is a placeholder assumed to be called by any function whose definition is not known. Yields this beauty (oh my, the size without optimizations turned on was too big!)

Clients will always obtain the smart pointer object through a factory in order to invoke D.ĭoes anyone know how to achieve this? SOLUTION 1 : static void D() $1 != id' | dot -Tpng -ocallgraph.png In my case, D is a member function of a class whose object will be wrapped within a smart pointer. I have tried Codeviz and Doxygen, somehow both results show nothing but callees of target function, D. You can report or view Graphviz bugs and issues by visiting the Graphviz Issues page.I'm trying to generate calling graph with which to find out all the possible execution paths that are hitting a particular function (so that I don't have to figure out all the paths manually, as there are many paths that lead to this function). You can post questions and comments in the Graphviz forum. The current release of Graphviz can be downloaded here: Downloadĭocumentation is available in the released package and from here: Documentation Discussions Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes.

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages PDF or Postscript for inclusion in other documents or display in an interactive graph browser. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Graphviz is open source graph visualization software.
