SANE compiling with patch for HP 4470c

[Thomas Luft <mailings@luto.de>]

Hi,

I tried to compile the libsane package I downloaded via apt-get source 
to add support to my HP 4470c scanner (sources by Johannes Hub, 
http://home.foni.net/~johanneshub/). Unfortunately I don't know much 
about compiling and C programming but it seemed quite easy until I got 
the following error:

make[2]: *** [v4l.lo] Fehler 1
make[2]: Leaving directory `/home/cpblu01/src/sane-backends-1.0.12/backend'
make[1]: *** [all-recursive] Fehler 1
make[1]: Leaving directory `/home/cpblu01/src/sane-backends-1.0.12'
make: *** [build-stamp] Fehler 2
debuild: fatal error at line 554:
dpkg-buildpackage failed!

I tried to compile the sources without the patch from Johannes but the 
error is still the same.

Can somebody tell me what goes wrong? Is there a library or a -dev-file 
missing

Sorry, for this stupid question, but I have no idea which line 554 is 
meant and what is wrong!?

Regards

Thomas
