Pyipopt used to work on this computer, but after trying to make Ipopt interface with Matlab, pyipopt has since stopped working. Installation of Ipopt and pyipopt produces no errors. Ipopt's hs071_c works fine.
When I try to run pyipopt's example hs071.py, or any other python code that uses pyipopt, this error gets produced:
Traceback (most recent call last):
File "hs071.py", line 6, in
import pyipopt
File "/usr/local/lib/python2.7/dist-packages/pyipopt/init.py", line 16, in
from pyipoptcore import *
ImportError: /usr/local/lib/python2.7/dist-packages/pyipopt/pyipoptcore.so: undefined symbol: _ZTVN10__cxxabiv117__class_type_infoE
I have uninstalled and reinstalled Ipopt and pyipopt various times, but the error still gets thrown when hs071.py is run.
Running on Ubuntu 16.04 dual-booted with Windows 10
