Hello-
Is there a way to code a callback to python from
fortran in a way such that the calling routine does
not need the callback function as an input argument?
I'm using the Intel fortran compiler for linux with
numpy 1.0.4 and f2py gives version 2_4422. My modules
crash on loading because the external callback
function is not set. I noticed in the release notes
for f2py 2.46.243 that it was a resolved issue, but I
don't know how that development compares to version
2_4422 that comes with numpy.
The example that I was trying to follow is from some
documentation off of the web:
subroutine f1()
print *, "in f1, calling f2 twice.."
call f2()
call f2()
return
end
subroutine f2()
cf2py intent(callback, hide) fpy
external fpy
print *, "in f2, calling fpy.."
call fpy()
return
end
f2py -c -m pfromf extcallback.f
I'm supposed to be able to define the callback
function from Python like:
>>> import pfromf
>>> def f(): print "This is Python"
>>> pfromf.fpy = f
but I am unable to even load the module:
>>> import pfromf
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: ./pfromf.so: undefined symbol: fpy_
>>>
Any ideas?
Thank you-
Dan
