SyntaxError: invalid syntax

[jintianyun56]

Hi there,
I have settings.cfg but have to change ConfPrune.pyx as ConfPrune.py, otherwise, the PyDP4.py can't find ConfPrune.
I tried to run the sample AT1.sdf.
Running "PyDP4.py -s chloroform -m m -B 6-311g* -F mPW1PW91 --AssumeDFTDone AT1_ AT1NMR" in the ./MM/ file show error

File "/home/tj/DP5_master/ConfPrune.py", line 37
cdef long int c1, c2
^^^^
SyntaxError: invalid syntax

would you like to help me to fix it?
Thanks

It looks like you have a problem with Cython. I suggest the following workaround:

1. delete ConfPrune.pyx from your DP5 folder
2. download ConfPrune.txt and paste into your DP5 folder as ConfPrune.py
3. In PyDP4.py, replace the following lines:

if os.name == 'nt':
    import pyximport

    pyximport.install()
    import ConfPrune
else:
    import pyximport

    pyximport.install()
    import ConfPrune

with import ConfPrune

Let me know if this helps
