Hi Thomas,
I hope someone will find the time to integrate the flext-based externals into the autobuild structure.
Sorry but I can't: it's beyond my skills.
I've got another problem now (ubuntu 9.04 64-bit machine PD 0.42.5):
in the example buffer-1.pd (py/pyext) there's a strange behaviour: the message [mul array3 array1 array2< works only on the first half of the array3 instead the message [add array3 array1 array2<
the difference is in th buffer.py:
def mul(*args): # create buffer objects # as long as these variables live the underlying buffers are locked c = pyext.Buffer(args[0]) a = pyext.Buffer(args[1]) b = pyext.Buffer(args[2])
# slicing causes Python arrays (mapped to buffers) to be created # note the c[:] - to assign contents you must assign to a slice of the buffer c[:] = a[:]*b[:]
def add(*args): c = pyext.Buffer(args[0]) a = pyext.Buffer(args[1]) b = pyext.Buffer(args[2])
# explicit casting to arrays is also possible c[:] = N.array(a,dtype=N.float32) + N.array(b,dtype=N.float32)
therefore I think that: - the direct use of the buffer doesn't work well (printing the values give me something like "0 0.123 0 0.234 0 0.345 etc.. " - correct values followed by a zero) - the casting works well
My questions are: - am I missing some basic concept? - this behaviour is correct (I don't think so)? - this behaviour is due to the 64-bit?
Thanks, ciao, Dario.
PS: Sorry for the bad english.

thanks for your kind words. I haven't given up the hope that someday someone will find the time to integrate the flext-based externals into the autobuild structure and, consequently, pd-extended. gr~~~

Thanks a lot Thomas.
Now it compile fine!
I pick the occasion to say that your work for pd (flext, pool, py,
etc...)
is fantastic. Many many many thanks!
ciao, Dario

Hi Dario, please check out py from svn and try again. gr~~~ Am 09.03.2010 um 09:48 schrieb Dario Pedrioli:
Hi all,
I'm trying to compile py/pyext on ubuntu 9.04 64-bit machine PD 0.42.5
with flext rev 3659 I've got no problems.
with flext rev 3723 I've got the error below:

Someone can help?
PS: I'm trying rev 3723 because of 64-bit buffer patch (
http://markmail.org/message/6v52tlvllwvcwilj#query:+page:1+mid:6hpplp4wfi4u6... gr@grrrr.org
) My goal is to handle arrays directly in python, but with the rev 3659
I'm
only get half of the array inside py (the other half is set to zero). Am
I
on the right way to fix my problem?
