[sane-devel] Unknown SANE status code -1081075667

[carterbueford at gmx.net]

Hi,

@allan: I do not run xsane on the same mashine like the sane-server, so I do not understand how to write the log you want me to.
"xsane... 2>net.log"
sanimage on the mashine where the sane-server runs, works fine.

@Olaf:"Compile the backend with gcc -Wall -Werror should give a cluebat." What is meant by that?
I'm using the optware package, so it is not compiled on my router. I am maintainer of the package, so I can patch it to be compiled in a different way, but how?

Regards
Oliver

Eh, if you don't tell it to do so, yes.  Using variables before
initialisation has been undefined behaviour since as long as I
know.

Compile the backend with gcc -Wall -Werror should give a cluebat.
