Can you say how it failed? I would be inclined to start with the simplest possible import/export using bytes: mpz_export(buf, *count, 1, 1, 0, 0, mpz) and: mpz_import(mpz, count, 1, 1, 0, 0, buf) Since it seems that the length of the data (i.e. count) has to be input, you need to recover this in some way on export so it can be used on import. Using bytes avoids a lot of issues with byte order and should work. If it doesn't, I suspect something is broken.
