That's pretty cool stuff. I tried to build the API reference with doxygen. What I did was really easy. You must use the terminal. 1. Install doxygen. sudo apt install doxygen 2. Install graphviz sudo apt install graphviz 3. Go into the kstars directory and execute doxygen -g doxy.cfg You can choose every filename you want. 4. Make some changes to doxy.cfg I made these changes: PROJECT_NAME = "KStars" OUTPUT_DIRECTORY = /home/your_name_here/doxy-kstars RECURSIVE = YES Save your changes. 5. Run doxygen doxy.cfg The result is in the ouput folder and you get a nice reference with graphs. Enjoy! There is certainly more to it. But I have no clue.Read More...
