cec.init() fails to open with garbage error message. #16

Open TomCarlosCumming opened 7 years ago

TomCarlosCumming commented 7 years ago

On a raspberry pi zero, I get the following error on open. Python-cec was installed using the README.md 0.2.5 recipe (wget... to pip install cec).

cec-client works fine on same pi, tv, etc.

I had a similar problem, though instead of garbage I got a straight segfault on 'log_cb' when running 'cec.init()' (python 3.6, libcec 4.0.2, cec 0.2.6).

I didn't really bother finding the root cause, but I found that building from the repo and replacing 'cec.so' from pip with the git-built version (5a2a6c8) resolved the issue for me.
