"__udivdi3" is undefined

[Sergey Kostyuk]

This problem is described in README

the driver uses division of 64-bit numbers, thereas kernels on 32-bit intel architecture dont have support of such division. libgcc.a includes object file (_udivdi3.o or _udivdi.oS) which implents _udivdi3 symbol. Put that _udivdi3.o file  into src/ directory of the latest SVN version of driver and fix Makefile according README. After that make will be OK

Sergey,

your solution looks like a big hack(tm) to me. I think using do_div is much cleaner.
Have a look at http://www.captain.at/howto-udivdi3-umoddi3.php
I would fix it by my selfe and send you a patch, but I think you find better the places where you do a 64-bit div.

Big hack (c) is fixed. Thx Christian for important remark.

All changes are in SVN

Please, check your /var/log/messages for string "SIGMA video 0: dicom Kmin set into VALUE"
default VALUE must be 0x1083 or something like this
If VALUE is different from expected, let me know
