1) I get a message saying "Failed to find Scanner device" when
starting epscan. 

There are several possibilities:
	1) You don't have SCSI generic support compiled into your
kernel.  When you configure your kernel, you must answer yes to the
question about "SCSI generic support."
	2) You must have devices /dev/sg[a-h] in your /dev/
directory.  If they don't exist, log in as root, cd to /dev, and type
"MAKEDEV sg".
	3) The /dev/sg* devices exist, but they don't have read
permission for anyone other than root.  In this case you have three
choices.  Either change the permissions on the sg devices, using the
command "chmod 666 /dev/sg*", or make epscan suid-root, using the
command "chmod 4755 epscan".  Or you can just use epscan when logged in as
root.


2) What is this "moc" thing that make asks for?

"moc" is a preprocessor that comes with the Qt library.  It is
necessary to compile Qt programs.  If you have Qt already, then moc is
probably in QTDIR/bin, where QTDIR is the directory that you installed
Qt in.  If you don't already have Qt, you need to download it.  Qt's
homepage is <http://www.troll.no>.


3) Where is "sg.h"?

This is the SCSI generic include file.  It should be located under
/usr/include/scsi/ which is really a link to
/usr/src/linux/include/scsi.  If it's in the latter location, but you
just don't have the link under /usr/include, then execute the following
command to create the link.
	ln -s /usr/src/linux/include/scsi /usr/include/scsi
For some older kernels, (before 2.0 at least), it is located under
/usr/src/linux/drivers/scsi/sg.h.  I have now created a configure
script which checks both of these locations, but if it's not in either
place, let me know what kernel version you have.

4) Missing include files that start with the letter 'q'. :)

These are the Qt include files.  If you already have Qt, set the QTDIR
environment variable to the Qt lib directory.  For example, if the Qt
include files are in /usr/lib/qt/include, then set QTDIR to
/usr/lib/qt.  Then run "make realclean" and "configure" again.
If you don't have Qt, you can download it from http://www.troll.no.

5) I get an error message about TIFFRGBA* being undefined.

You need to get a newer version of libtiff.  You can get this from 
	ftp://sunsite.unc.edu/pub/Linux/libs/graphics/libtiff-3.3-ELF.tar.gz
	ftp://sunsite.unc.edu/pub/Linux/libs/graphics/libtiff-3.3l1.tar.gz
or from 
	ftp://ftp.sgi.com/graphics/tiff/

6) I found a bug/have a problem.

Please send me email <ajenkins@cs.umass.edu>.  Please include the
kernel version you're using, the Qt version, what scanner model you
own, and what error messages you got (cut and paste if possible.)
