[sane-devel] Testing on Canon MF6580PL

[twain43 at hotmail.com]

Ehm...sorry everybody, been out of town a few weeks, couldn't get my hands on the mail....I'm back to the testing board.

I just read your posts, and wanted to sum up the steps to take. Do please, correct me if I'm wrong:
1. Change backends/pixma_common.h around line 57 from "#ifdef NDEBUG" to "#ifdef NDEBUGBLAAAA". 
2. Same thing for backends/pixma.c line 70.
3. compile, install and test.

@Nicolas: if I understood your post below, you're suggesting I use "#ifdef NDEBUGPIXMA", instead of the above....am I right?
