Doxygen plugin: "The output directory could not be read from the configuration."

[David Doria]

I am trying to use the Doxygen plugin. I have specified my Doxygen configuration file and it seems to be found (as if I specify a file that doesn't exist that plugin GUI complains right away). However, when the post-build action runs, I get ""The output directory could not be read from the configuration." I have set OUTPUT_DIRECTORY to both nothing and to '.', but I get the same error. I have also tried setting the "Folder from which doxygen is run" in the advanced options to the folder that the doxygen configuration file is in, but I still get the same error. Any suggestions?

Thanks,

David
