4 years ago Do you have an old version of coreir installed in your path, perhaps in /usr/local/lib ? You can check with ls /usr/local/lib | grep coreir, if so, you'll want to go to wherever you built/installed coreir (probably a local clone of the repo) and run make uninstall to remove the files. My suspicion is that the pycoreir package is trying to use your local installation rather than the packaged wheel and it's finding an incompatible library (e.g. one compiled before COREBitInOut was introduced). Alternatively, you can try compiling/installing a new version of coreir from source (this is separate from the python package), but if you don't need bleeding edge features off of master, I would suggest using the pypi package wheel distribution if possible.
