  Hi Petter,

  the help says:

  $ sane-config -h
  Usage:
  sane-config --libs - libraries required to link with SANE

  So it should print the libs that a required to link a program with sane
  and not the ones the sane libs are linked against.

  $ ldd /usr/local/lib/sane/libsane-dll.so
  libc.so.6 => /lib/libc.so.6 (0x4000e000)
  /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

  it looks like ld (=ld-linux?) is already linked to libsane-dll,
  the other ones are not needed (If I compile xscanimage without
  linking nsl, jpeg and intl everything works fine)!

  I think that if the required libs are linked to the sane backends
  it should be enough if a frontend links against libsane.

  So if a backend needs a jpeg library, the library has to be linked
  to the backend lib not to the frontend.

  So the output of sane-config should be "-lsane" ?!

  Bye
  Oliver
