error using doxygen and graphViz: problems opening map file

The following method worked for me on Windows 10 with Doxygen 1.8.14.

Open cmd and type dot -c. Then, delete the doxygen output folder and regenerate it.

Make sure you have graphviz in your path. My graphviz is installed at C:\Program Files\Graphviz 2.44.1. So, there is no problem, even if spaces are there.

I got this message 'problem opening map file for inclusion in the docs', if doxygen is not able to find graphviz/dot in the path. Try setting the path explicitly using DOT_PATH in the doxyfile.

As albert, already mentioned remove any whitespace in the path to the output path.

Another good idea is to completely remove your output directory, e.g. html, and regenerate your documentation.

It also seems that doxygen is for activating dot.exe space sensitive. Make sure your path is like this or at least without whitespaces:

D:/Graphviz2.38/bin

based on experience of Graphviz 2.38 on windows 10
