eldoc error: (void-variable comint-last-prompt-overlay)

[chfw]

Hi all

I am using emacs 25.1.1 on mac and I have up to date emacs-for-python. Eldoc stopped working due to no inferior python process. However, I did m-x run-python and eldoc still shows error. Any advise please?

Thanks

ok, I've solved it by replacing extensions/python.el with the version from https://github.com/emacs-mirror/emacs.
The error is due to changes in emacs introduced in 2013.

You can get it also from my fork https://github.com/lpryszcz/emacs-for-python
