Hey David, you should be able to store your bits in a vector. First of all, unpack_k_bits will yield bytes with the LSB carrying the actual bit. All the others should be '0'.
Next, the error you get points in another direction. One of the parameters 'work' gets is a vector with void pointers. It's up to you to deal with them correctly. Most block's work functions start with converting those void pointers to the actual data type they're supposed to deal with. e.g. const float* in = (const float*) input_items[0]; in your case the compiler complains that you don't do a conversion to int. Be aware that 'unpack_k_bits' deals with char. Thus casting your input buffer to int, will cause some unindented beaviour. from 'pack_k_bits' const unsigned char *in = (const unsigned char *)input_items[0]; and then do something like vec[i] = (int) in[i]; in a loop.
