Tool to Map #include's

Question

Is there a tool available which will take a set of source files and map (in graphic fashion) how they are linked via #include?

I would like to see where there are any circular references.

Answer 1

I believe doxygen:

http://www.doxygen.org/

with graphviz installed:

http://www.graphviz.org/

will do it.

Answer 2

gcc(1) can produce dependency files. They are intended to be used by make(1), but they are relatively easy to parse. Use 'gcc -M -MF file' or 'gcc -MM -MF file'.

Answer 3

Red Hat source navigator. Strongly recommended.
