python not working on ubuntu 14.04

[linas]

I have a laptop here, Ubuntu 14.04, with minimal install and setup, and I am getting this:

Traceback (most recent call last):
  File "./example.py", line 9, in <module>
    print ("Version:", clg.linkgrammar_get_version())
AttributeError: 'module' object has no attribute 'linkgrammar_get_version'

Running things manually gives:

python
Python 2.7.6 (default, Nov 23 2017, 15:49:48) 
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from linkgrammar import Sentence, ParseOptions, Dictionary
>>> 
>>> sent = Sentence("This is a simple sentence.", Dictionary(), ParseOptions())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/linkgrammar/linkgrammar.py", line 329, in __init__
    self._obj = clg.dictionary_create_lang(lang)
AttributeError: 'module' object has no attribute 'dictionary_create_lang'

So,

nm /usr/local/lib/python2.7/dist-packages/linkgrammar/_clink*so 

indicates that the so is nearly empty, viz, the bindings were not actually built ... the so only contains the minimal stuff needed for an so.

[linas]

Seems that lg_python_wrap.cc is empty ...

This is apparently because I do not have swig installed, and I am building from git.

[linas]

Yeah. User error. Our Makefile.am does not warn when SWIG is missing, and the SWIG-generated files are also missing. This is leds to confusion, when compiling from git.
