[sane-devel] Viceo and Visioneer 6100 USB

Sun May 19 04:55:55 BST 2002

I have Visioneer 6100 USB scanner and have been trying to get it working. I 
know it works because I was able to use Steven Charlie's e3 patch v 0.4 with 
sane, and it worked fine. Now I wish to get the newer patch to work but am 
having difficulty compiling the drivers and I am asking for some help. When 
compiling the drivers these are the errors/warnings I am getting, any help 
would be greatly appreciated. (Sorry if its a bit long):

(This may be normal but I thought I would paste it anyways.)
