Hi Janne.

Doxygen uses DOT to generate the call graphs. Doxygen possibly simply 
does not find DOT. Try to explicitly set DOT_PATH.

For testing you can also say DOT_CLEANUP = NO. You should find a lot of 
*.dot files in your output folder then. This is what Doxygen gives to 
DOT to convert to PNG images. If these *.dot files are not there, then 
the problem is not related to DOT.

You should have lines like the following in your output:
"Generating call graph for function FOO"
"Generating caller graph for function FOO"

Last question: Do you see missing PNG graphic files in you HTML output?
If yes the issue is presumably related to DOT. If the HTMLs not even 
have any references to the call graph graphic files then it is a 
configuration error.
