Hello,

I try to install psi but I get an error:

ImportError: build/lib.linux-i686-3.2/psi/_psi.cpython-32mu.so: undefined symbol: PyCObject_FromVoidPtr

best regards

Olivier Fournier

Hi Olivier,

On 3 November 2011 19:34, o.fourn...@iktios.fr <o.fourn...@iktios.fr> wrote:

I'm afraid this is because I haven't updated the code to use a newer
Python/C API.  psi uses the old PyCObject API, which was the only one
available when we wrote that part, rather then the newer PyCapsule
one.  But what I didn't realise is that they stopped providing the
PyCObject API in 3.2, that's a bit sooner then I expected even though
I knew there where deprecation warnings in 2.7 and 3.1.

I'll check out how much work it is to update psi and then do a release
with that fix in.  Can't make any promises on a timeline however.  In
the mean time you'll have to revert the a version of python before 3.2
I'm afraid.

Regards,
Floris

I've checked in a fix at our repository:
https://bitbucket.org/chrismiles/psi/ so you can use a snapshot from
there.  A release will hopefully follow soon.
