I will be looking to set this up in the near future. I do not yet
seen any references for setup instructions for such a combination
"doxygen + graphviz". Does anyone have any pointers for such a thing?
To answer my own question:
One must install graphviz per their install instructions (I did so on
a WinXP system using the Windows binaries...I wasn't sure whether or
not to put the "thirdparty" stuff in, but I did so right on top of the
graphviz install dirs).
Then one must set the appropriate DOT* variables in the Doxyfile
config file, namely the HAVE_DOT variable. 'dot' or 'dot.exe' is
found in the graphviz distribution. Put dot.exe's path in the system
PATH variable on Windows (alternative, point DOT_PATH to the to this
same path...but I could not get this to work).
After doing all this I was able to make some nice graphs. There are
other Doxyfile config settings/variables that can produce more or less
graphical stuff.
