[python-control-discuss] Slycot import error

[Gustavo G. <gor...@mi...>]

I'd like to use the LQR routine in python-control. I just cloned the
Slycot repo from here [1] and am having an issue that is certainly not
due to python-control, but I thought I might get a helpful response
anyway.

When I (or python-control) issues "import slycot", here's the result:

Python 2.6.6 (r266:84292, Sep 15 2010, 16:22:56)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import slycot
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "slycot/__init__.py", line 4, in <module>
   from slycot.analysis import ab01nd,ab05md,ab05nd,ab07nd,ab08nd, ab09ad
 File "slycot/analysis.py", line 21, in <module>
   from slycot import _wrapper
ImportError: cannot import name _wrapper


There is a file called slycot/src/_wrapper.pyf, which is presumably
the file that wants to be imported.

Any suggestions?

Thanks,
Gustavo
