Why are there so many error messages by compiling this simple code ?

Hi @Animalia. It seems like ctcsound.py can’t find csound64.dll/csound64.lib files :thinking:

If you are using ctcsound installed with pip you can try to remove it and use ctcsound that came with csound.

One way to do that is by manually adding path of your ctcsound.py file:

import sys
sys.path.append("C:\Program Files\Csound6_x64\bin")  
import ctcsound

If your path is different, then of course you need to change path above accordingly.
