If you’re building a swig Python module and encounter errors like:<\/p>\n
AttributeError: 'Foobar' object has no attribute 'this'<\/pre>\nwhere Foobar is some class that is being wrapped, then you are encountering a swig-3.08 bug. \u00a0Unfortunately this is still the official package in Ubuntu 16.04. \u00a0You can vote for the issue here<\/a>.<\/p>\n
Until the package is updated, one can download and manually install an updated swig package by following the following recipe:<\/p>\n
