[myhdl-list] Help with initial config of MyHDL on Ubuntu 9.04

[Kevin S. <sta...@gm...>]

Hi,

I can't seem to find anything on what might be going wrong, but I just
installed MyHDL and tried to run a few of the examples.

I went into :

cd myhdl-0.6/example/rs232

and ran:

python test_rs232.py

All of the tests fail, and I get back several errors that look exactly like
this:

Traceback (most recent call last):
  File "test_rs232.py", line 102, in testCharacterize
    Simulation(self.bench(tx_baud_rate)).run(quiet=1)
  File "/usr/local/lib/python2.6/dist-packages/myhdl/_Simulation.py", line
132, in run
    waiter.next(waiters, actives, exc)
  File "/usr/local/lib/python2.6/dist-packages/myhdl/_Waiter.py", line 113,
in next
    (repr(clause), type(clause)))
TypeError: yield clause <myhdl._instance._Instantiator object at 0xa1a506c>
has type <class 'myhdl._instance._Instantiator'>

I am not a novice at VHDL, or Python for that matter, but this error message
is confusing because it appears to be complaining about a TypeError, but the
types listed match...

What am I missing?

Thanks in advance for anyone who can be of help!

Kevin

Which version of Python do you have?  I double checked the rs232 in the 
latest dev snapshot with python 2.6 with success.

You can get the latest development snapshot from
   http://www.myhdl.org/doku.php/dev:repo
using mercurial.

p.s. I also downloaded 0.6 and reproduced the same error, I am not sure 
what the error is but it does not fail with the latest development snapshot.

Maybe a new release should be cut?  Probably would just be a bug fix 
release no new major features?

Hope that helps.

Chris,

Thanks for your help.  I actually had to do:

hg clone http:/hg.myhdl.org/myhdl myhdl

But once I did that, I did:

sudo python setup.py install

And then ran the rs232.  Everything works!

Should probably cut a new release...

Thanks again!

Kevin

Yes, there was an issue related to the more general use
of decorators, fixed in development.

You have a point :-)
