What do you mean by worked well? Since chip a GL845, it won't work
with GL847 code.

In order to test a newly compiled version, you can run it with the
attached script (edit it to adapt it for the exact location of sane
sources on your PC).
The debugging output (preview.pnm and preview.log) will help the
development and fixes of the backend part for GL846.
