I have installed liclipse 2.4 (Python 3.0 grammar) recently and downloaded pycparser-master.zip file, extracted it, and added the pycparser-master/pycparser/ directory under Project->Properties->PyDev-PYTHONPATH->External Libraries.
I used the below import statement in my Python file.
import pycparser
But the interpreter seems to be throwing an error.
Unresolved import: pycparser
The problem is that you should put "pycparser-master" as the folder in the external libraries (and not pycparser-master/pycparser).
