Hi friends,
Before asking for such help, I would like to emphasize that already have read every page of google referring to SCX-4521F in linux, including several post this excellent forum.
Do not use windows to more than 8 years and do not intend to re-use. However I did a good investment that's laser multifunctional Sansung and accurate than the scanner work.
I installed the most current drive available on the Samsung. I did all procedures outlined by the company and still not worked, not even turning the xsane as root.
We also tried the recommendations as a forum for editing and replace the libmfp.so.1.0.1. Nothing said.
The problem is that when the road xsane he simply closes. Following the following error message:
To try to discover the error executed the following command:Code:root@desktop:/home/thiago/source/fix-nopar/i386# xsane *** glibc detected *** xsane: double free or corruption (!prev): 0x08236e78 ***
