BEFORE YOU BEGIN

    You'll need ANSI-compliant C and C++ compilers, plus a make program and
    POSIX-compliant shell (/bin/sh).  The GNU compiler tools and Bash work well
    and we have tested the current CUPS code against several versions of GCC
    with excellent results.

    The makefiles used by the project should work with most versions of make.
    We've tested them with GNU make as well as the make programs shipped by
    Compaq, HP, SGI, and Sun.  BSD users should use GNU make (gmake) since BSD
    make does not support "include".

    Besides these tools you'll want the JPEG, PNG, TIFF, and ZLIB libraries for
    image support, the CDSA, GNU TLS, or OpenSSL libraries for encryption
    support, the OpenLDAP and OpenSLP libraries for directory services support,
    and either MIT (1.6.3 or higher) or Heimdal Kerberos for Kerberos support.
    CUPS will compile and run without these, however you'll miss out on many of
    the features provided by CUPS.

    Also, please note that CUPS does not include the Ghostscript-based
    PostScript filter needed by non-PostScript printers.  You *must* download
    GPL Ghostscript separately from the CUPS web site if you want to print
    PostScript files to non-PostScript printers on operating systems other than
    OS X.


COMPILING THE SUBVERSION REPOSITORY CODE

    The CUPS Subversion repository doesn't hold a copy of the pre-built
    configure script.  You'll need to run the GNU autoconf software (2.60 or
    higher) to create it:

	autoconf


CONFIGURATION

    CUPS uses GNU autoconf, so you should find the usual "configure" script in
    the main CUPS source directory.  To configure CUPS for your system, type:

	./configure

    The default installation will put the CUPS software in the "/etc", "/usr",
    and "/var" directories on your system, which will overwrite any existing
    printing commands on your system.  Use the "--prefix" option to install the
    CUPS software in another location:

	./configure --prefix=/some/directory

    To see a complete list of configuration options, use the --help option:

        ./configure --help

    If any of the dependent libraries are not installed in a system default
    location (typically "/usr/include" and "/usr/lib") you'll need to set the
    CFLAGS, CPPFLAGS, CXXFLAGS, DSOFLAGS, and LDFLAGS environment variables
    prior to running configure:

	setenv CFLAGS "-I/some/directory"
	setenv CPPFLAGS "-I/some/directory"
	setenv CXXFLAGS "-I/some/directory"
	setenv DSOFLAGS "-L/some/directory"
	setenv LDFLAGS "-L/some/directory"
	./configure ...

    or:

	CFLAGS="-I/some/directory" \
	CPPFLAGS="-I/some/directory" \
	CXXFLAGS="-I/some/directory" \
	DSOFLAGS="-L/some/directory" \
	LDFLAGS="-L/some/directory" \
	./configure ...

    The "--enable-debug" option compiles CUPS with debugging information
    enabled.  Additional debug logging support can be enabled using the
    "--enable-debug-printfs" option - these debug messages are enabled using the
    CUPS_DEBUG_LOG environment variable at run-time.

    CUPS also includes an extensive set of unit tests that can be used to find
    and diagnose a variety of common problems - use the "--enable-unit-tests"
    configure option to run them at build time.

    Once you have configured things, just type:

	make ENTER

    or if you have FreeBSD, NetBSD, or OpenBSD type:

	gmake ENTER

    to build the software.


TESTING THE SOFTWARE

    Aside from the built-in unit tests, CUPS includes an automated test
    framework for testing the entire printing system.  To run the tests, just
    type:

	make check ENTER

    or if you have FreeBSD, NetBSD, or OpenBSD type:

	gmake check ENTER

    The test framework runs a copy of the CUPS scheduler (cupsd) on port 8631
    in /tmp/cups-$USER and produces a nice HTML report of the results.


INSTALLING THE SOFTWARE

    Once you have built the software you need to install it.  The "install"
    target provides a quick way to install the software on your local system:

	make install ENTER

    or for FreeBSD, NetBSD, or OpenBSD:

	gmake install ENTER

    You can also build binary packages that can be installed on other machines
    using the RPM spec file ("packaging/cups.spec") or EPM list file
    ("packaging/cups.list").  The latter also supports building of binary RPMs,
    so it may be more convenient to use.

    You can find the RPM software at:

	http://www.rpm.org/

    The EPM software is available at:

	http://www.epmhome.org/


CREATING BINARY DISTRIBUTIONS WITH EPM

    The top level makefile supports generation of many types of binary
    distributions using EPM.  To build a binary distribution type:

	make <format> ENTER

    or

	gmake <format> ENTER

    for FreeBSD, NetBSD, and OpenBSD.  The <format> target is one of the
    following:

	epm       - Builds a script + tarfile package
	aix       - Builds an AIX package
	bsd       - Builds a *BSD package
	deb       - Builds a Debian package
	depot     - Builds a HP-UX package (also swinstall)
	inst      - Builds an IRIX package (also tardist)
	pkg       - Builds a Solaris package
	rpm       - Builds a RPM package
	setld     - Build a Tru64 UNIX package
	slackware - Build a Slackware package
	swinstall - Build a HP-UX package (also depot)
	tardist   - Builds an IRIX package (also inst)


GETTING DEBUG LOGGING FROM CUPS

    When configured with the "--enable-debug-printfs" option, CUPS compiles in
    additional debug logging support in the scheduler, CUPS API, and CUPS
    Imaging API.  The following environment variables are used to enable and
    control debug logging:

        CUPS_DEBUG_FILTER  Specifies a POSIX regular expression to control
	                   which messages are logged.
	CUPS_DEBUG_LEVEL   Specifies a number from 0 to 9 to control the
	                   verbosity of the logging. The default level is 1.
        CUPS_DEBUG_LOG     Specifies a log file to use.  Specify the name "-"
	                   to send the messages to stderr.  Prefix a filename
			   with "+" to append to an existing file.


REPORTING PROBLEMS

    If you have problems, READ THE DOCUMENTATION FIRST!  If the documentation
    does not solve your problems, please post a message on the "cups.general"
    forum at:

        http://www.cups.org/newsgroups.php

    Include your operating system and version, compiler and version, and any
    errors or problems you've run into.  The "config.log" file and the output
    from the configure script and make should also be sent, as it often helps to
    determine the cause of your problem.

    If you are running a version of Linux, be sure to provide the Linux
    distribution you have, too.
