Incompatible pointer type

I encounter this error at compile time.

/Users/lfr001/src/chemtensor/pymodule/pymodule.c:544:18: error: incompatible function pointer types initializing 'initproc' (aka 'int (*)(struct _object *, struct _object *, struct _object *)') with an expression of type 'int (PyOpChainObject *, PyObject *, PyObject *)' (aka 'int (PyOpChainObject *, struct _object *, struct _object *)') [-Wincompatible-function-pointer-types]
