SANE on Windows

Prerequisites
=============

To be able to compile sane-backends, you need to have either Cygwin
or Mingw compilers and a suitable POSIX compatible environment.

You can get the Cygwin POSIX compatible environment for Windows
Windows and the Cygwin gcc compiler at http://www.cygwin.com

You can get the MSYS POSIX compatible environment for Windows and the
MinGW gcc compiler at http://www.mingw.org/wiki/MSYS

The scanner must be detected by Windows and not be disabled. Check
with the hardware manager.


Building
========

See general README for build basics. If a given backend fails to
compile, you can use the BACKENDS variable to limit compilation
to backends your interested in:

  ./configure BACKENDS=epson2


Configuring
===========

If you have more than one scanner, you should do the following:

  - run sane-find-scanner to get the device name of the scanner. The
    name for scsi devices is something like h0b0t6l0, meaning hba 0, bus 0,
    scsi id 6 and lun 0.

  - edit the config file for the backend
    (/path/to/sane/etc/sane.d/xxxx.conf) and add the scanner device name on
    an empty line.

  - Set environment variable SANE_CONFIG_DIR to point to the directory
    where the config files are located.

Run "scanimage > out.pnm" to get a scan.

xscanimage ans XSane have been reported to compile and run in the past
under Cygwin.

Notes
=====

- Only SCSI, USB (with libusb-win32), and network scanners may work. No
  FireWire/Parallel. The Cygwin libusb port can be installed
  with Cygwin setup.exe or can be compiled manually under cygwin
  or mingw using the libusb-win32 port:
  http://sourceforge.net/apps/trac/libusb-win32/wiki

- Tested on Windows XP, 7, and using Wine on Linux.

- Some scanners' backend may not work because of requirement not
  supported by Cygwin or MinGW.
