Re: [pypy-dev] dlopen NotImplementedError
Hi, 2010/12/23 Maciej Fijalkowski fij...@gmail.com CDLL(None) (or LoadLibrary(None)) is supposed to return to you the whole namespace (all loaded libraries). It's unsupported as far as I can tell. It should work by now (on Unix platforms of course). -- Amaury Forgeot d'Arc ___ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
[pypy-dev] dlopen NotImplementedError
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.

Re: [pypy-dev] dlopen NotImplementedError
Hmm, I'm thinking the dlopen error might be my problem. I think I built python at /root/pypy, and then moved it to a more proper location. But the error message is referring to /root/pypy, so I'm guessing it has that location hardcoded because that's where I built it? I'm going to rebuild but I wanted to post this message so that you guys don't worry about it (unless rebuilding doesn't help). -- Gary Robinson CTO Emergent Discovery, LLC personal email: gary...@me.com work email: grobin...@emergentdiscovery.com Company: http://www.emergentdiscovery.com Blog:http://www.garyrobinson.net ___ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev

From the dlopen man page: If filename is NULL, then the returned handle is for the main program. I imagine that's the case someone is trying to trigger with ctypes.LoadLibrary(None) (which is what the name `dlopen` is bound to in this context). On the other hand, maybe it's just a screw up somewhere else that causes None to show up instead of the right library name, I haven't looked at the code in question much.
