I have been using Python 3.8. I upgraded my scripts and needed 3.10 or above for some supported code.

I am getting the following issue:

ModuleNotFoundError: No module named '_ctypes'

Interesting. I issued this command under 3.8 and the new 3.12 and it sez the _ctypes in not found.

python3.12 -m _ctypes
/usr/local/bin/python3.12: No module named _ctypes

I did check the build output and it sez _ctypes is there:

checking for stdlib extension module _ctypes_test... yes

This error is coming out of PYMQI.

Is PYMQI verified against 3.12?

I can well imagine that _ctypes_test is not the same thing as _ctypes.

Where in PyMQI is this error coming from - can you show a bit more of the error information or is that all you get?

Cheers,

This was frustrating. I was running verification commands against the old, working, installation and was getting the same negative results. I checked the build output and it said it was there. I rebuild Python a 4th time. I do believe the instructions had one more command and then reinstalled MQPYI. Error went away.

BTW, I put ths code in my program for debugging. In the end it finally worked

Code:

try:
import _ctypes
print("The _ctypes module is available.")
except ModuleNotFoundError:
print("The _ctypes module is not available.")
