Error while executing django sphinx
In for sphinx-doc (i have never used django-sphinx) it would never work to run make html inside the build folder. You need to go one folder level up so that the folders build and source ar visible. Most likely you will see the Makefile file here as well.
Try to change directories and run make html again.
I have installed django sphinx for my project.After successful installation and sphinx quickstart operation, i tried for creating html inside the "build" folder using the command "make html" and it gives me the error 
"make: * No rule to make target `html'.  Stop.".
Any help..Thanks in advance.
