WebCython 0.16 introduced typed memoryviews as a successor to the NumPy integration described here. They are easier to use than the buffer syntax below, have less overhead, and can be passed around without requiring the GIL. They should be preferred to the syntax presented in this page. See Cython for NumPy users. WebBasically, we make cython believe we will use 64 bit int to generate the .c file, but by using a C header we will, in fact, define a 128 bit int (the definition in the .h file does not match what we put into the pyx file). Once Cython has generated the .c file, we can compile it with GCC without further trouble, as GCC does support 128 bit ints Raw
