Thank you very much for your work. Unfortunately, I have no experience with patching something like this so far. I did some research, though – seems to be quite doable. I’m familiar with the terminal etc. As I understand this, I have to apply the diff-file on the original file with the patch command. So far, so good – but I have no idea, which file it is. I couldn’t figure out by looking at the diff file.
If you could tell, on which file I have to apply this, that would be great! Thanks! Tobias Am 16.03.2016 um 01:33 schrieb m. allan noah: > I have attached a patch for the sane-backends source code.
