Hi, I am using pythononlisp(a unmaintained project) and trying to writing some python codes on that. Pythononlisp is dependent of cffi and this works perfectly fine in a 32-bit machine and fails in 64 bit machine. This is the error Attempt to do an array operation on #<Printer Error, obj=#x1000c10579: #<TYPE-ERROR @ #x1000c73d62>> which is not an array. this happens exactly when pythononlisp is trying to initiate the python module has someone faced this before? (cffi:defcfun ("Py_InitModule4" Py_InitModule4) :void (name :string) (methods :pointer) (doc :string) (self :pointer) (apiver :int)) and above is called like this: (Py_InitModule4 (first methods) methodptr (cffi:null-pointer) (cffi:null-pointer) 1011) -- regards, Prashanth http://munichlinux.blogspot.com
