[pypy-dev] dlopen NotImplementedError

[Gary Robinson]

So, as of today, I'm starting to do as much of my day-to-day work in pypy as I can.

The missing numpy is a problem, but one I can work around a enough amount of the time to make this effort worth my while.

I don't know how, or even whether, I should report certain kinds of problems I might run into. I would appreciate some feedback on that. I want to help by giving feedback in whatever form, and to what degree, the pypy devs desire.

For example, I can run some scripts in pypy 1.4 but not in pypy fast-forward because of an error involving dlopen(). Other scripts are unaffected by this problem, depending on what needs to be imported.

When I try to run fast-forward in interactive mode, I get the same error, which is pasted below.

And now for something completely different: ``- do you know berlin? - all of
it? - well, just berlin''
