Error initializing memoryview variable. This is my code:

cdef int *popref = <int*>malloc(popsize * sizeof(int))
cdef int [:] popref_mv = popref

And this is the error I am getting:

Error: cdef int [:] popref_mv = popref
         ^
   Expected an identifier or literal

Running Python 2.6.6, GCC 4.4.7, Cython 0.14.1 on Red Hat Linux.

Hmh, I don't think this will work without type casting: `cdef int [:] popref_mv = popref` – cel Jul 16 '15 at 21:54
[This link](http://stackoverflow.com/questions/18462785/what-is-the-recommended-way-of-allocating-memory-for-a-typed-memory-view) helps you `malloc` may circumvent for memoryview – Soner from The Ottoman Empire Jul 16 '15 at 22:28
Typecasting does not work....Tried it out already – zenith86 Jul 17 '15 at 13:04
Does it have to do something with the version of python I am using?? – zenith86 Jul 17 '15 at 13:05
