undefined symbol: Py_InitModule3 #43

Hi *,

I installed with sudo python3 -m pip install JACK-Client --user.

If I try to import the module with import jack, I see the following error:

~ $ python3 midi_ctl.py
Traceback (most recent call last):
File "midi_ctl.py", line 3, in <module>
import jack
ImportError: /usr/local/lib/python3.5/dist-packages/jack.cpython-35m-x86_64-linux-gnu.so: undefined symbol: Py_InitModule3

Any ideas?

BR, Ck

Regarding pip: The --user option tells pip to install the package only for the current user (in the home directory), therefore no root access and no sudo is required. This may or may not be related to your problem.

It looks like you have another Python module named jack installed. Your error message talks about a .so file (i.e. a compiled module). This module here doesn't use a compiler, it consists only of the main module file jack.py and (since version 0.4.3) an additional file named _jack.py.

Ok, thanks.

I removed the other pyjack package and now it's working.
