It was not copied from anywhere in particular, just collected things from here and there…

I’ve updated the link to the source, and the source itself, please try.

Cool, though so — thanks!

OK, so this is OSX-specific, something that stopped working around OSX 10.10 or so. I’ll post an update.

MBpro:dyn oliviaguest$ LD_LIBRARY_PATH=. python test.py
Traceback (most recent call last):

ImportError: dlopen(/Users/oliviaguest/GitHub/pdist/dyn/dyn.so, 2): Library not loaded: libcmean.so

It works for me with Python 2.7.12 (and cython-0.25.2) on Linux (and gcc is version 5.4.0).

On newer versions of OSX gcc is actually not gcc, but clang, and I never tested with these.

Try adding explict cast to malloc, i.e.

v = (double *)malloc(n*sizeof(double))

Error compiling Cython file:
————————————————————
…
double mean(int, double*)
from stdlib cimport *
def cmean(a):
n = len(a)
cdef double *v
v = malloc(n*sizeof(double))

m.pyx:7:14: Cannot assign type ‘void *’ to ‘double *’
building ‘dyn’ extension

This is the traceback.

What is the full error message? (Most probably an explicit cast is missing somewhere…)

Cannot assign type ‘void *’ to ‘double *’ error.
Can you help me with this?
