  1 rizwank 1.1 Basic Installation
  2             ==================
  3             
  4                These are installation instructions for GNU enscript.  The top of
  5                this file describes how to compile and install the software; at the
  6                bottom are instructions for configuring enscript.
  7             
  8                The `configure' shell script attempts to guess correct values for
  9             various system-dependent variables used during compilation.  It uses
 10             those values to create a `Makefile' in each directory of the package.
 11             It may also create one or more `.h' files containing system-dependent
 12             definitions.  Finally, it creates a shell script `config.status' that
 13             you can run in the future to recreate the current configuration, a file
 14             `config.cache' that saves the results of its tests to speed up
 15             reconfiguring, and a file `config.log' containing compiler output
 16             (useful mainly for debugging `configure').
 17             
 18                If you need to do unusual things to compile the package, please try
 19             to figure out how `configure' could check whether to do them, and mail
 20             diffs or instructions to the address given in the `README' so they can
 21             be considered for the next release.  If at some point `config.cache'
 22 rizwank 1.1 contains results you don't want to keep, you may remove or edit it.
 23             
 24                The file `configure.in' is used to create `configure' by a program
 25             called `autoconf'.  You only need `configure.in' if you want to change
 26             it or regenerate `configure' using a newer version of `autoconf'.
 27             
 28             The simplest way to compile this package is:
 29             
 30               1. `cd' to the directory containing the package's source code and type
 31                  `./configure' to configure the package for your system.  If you're
 32                  using `csh' on an old version of System V, you might need to type
 33                  `sh ./configure' instead to prevent `csh' from trying to execute
 34                  `configure' itself.
 35             
 36                  Running `configure' takes awhile.  While running, it prints some
 37                  messages telling which features it is checking for.
 38             
 39               2. Type `make' to compile the package.
 40             
 41               3. Optionally, type `make check' to run any self-tests that come with
 42                  the package.
 43 rizwank 1.1 
 44               4. Type `make install' to install the programs and any data files and
 45                  documentation.
 46             
 47               5. You can remove the program binaries and object files from the
 48                  source code directory by typing `make clean'.  To also remove the
 49                  files that `configure' created (so you can compile the package for
 50                  a different kind of computer), type `make distclean'.  There is
 51                  also a `make maintainer-clean' target, but that is intended mainly
 52                  for the package's developers.  If you use it, you may have to get
 53                  all sorts of other programs in order to regenerate files that came
 54                  with the distribution.
 55             
 56             Compilers and Options
 57             =====================
 58             
 59                Some systems require unusual options for compilation or linking that
 60             the `configure' script does not know about.  You can give `configure'
 61             initial values for variables by setting them in the environment.  Using
 62             a Bourne-compatible shell, you can do that on the command line like
 63             this:
 64 rizwank 1.1      CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
 65             
 66             Or on systems that have the `env' program, you can do it like this:
 67                  env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
 68             
 69             Compiling For Multiple Architectures
 70             ====================================
 71             
 72                You can compile the package for more than one kind of computer at the
 73             same time, by placing the object files for each architecture in their
 74             own directory.  To do this, you must use a version of `make' that
 75             supports the `VPATH' variable, such as GNU `make'.  `cd' to the
 76             directory where you want the object files and executables to go and run
 77             the `configure' script.  `configure' automatically checks for the
 78             source code in the directory that `configure' is in and in `..'.
 79             
 80                If you have to use a `make' that does not supports the `VPATH'
 81             variable, you have to compile the package for one architecture at a time
 82             in the source code directory.  After you have installed the package for
 83             one architecture, use `make distclean' before reconfiguring for another
 84             architecture.
 85 rizwank 1.1 
 86             Installation Names
 87             ==================
 88             
 89                By default, `make install' will install the package's files in
 90             `/usr/local/bin', `/usr/local/man', etc.  You can specify an
 91             installation prefix other than `/usr/local' by giving `configure' the
 92             option `--prefix=PATH'.
 93             
 94                You can specify separate installation prefixes for
 95             architecture-specific files and architecture-independent files.  If you
 96             give `configure' the option `--exec-prefix=PATH', the package will use
 97             PATH as the prefix for installing programs and libraries.
 98             Documentation and other data files will still use the regular prefix.
 99             
100                In addition, if you use an unusual directory layout you can give
101             options like `--bindir=PATH' to specify different values for particular
102             kinds of files.  Run `configure --help' for a list of the directories
103             you can set and what kinds of files go in them.
104             
105                If the package supports it, you can cause programs to be installed
106 rizwank 1.1 with an extra prefix or suffix on their names by giving `configure' the
107             option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
108             
109             Optional Features
110             =================
111             
112                Some packages pay attention to `--enable-FEATURE' options to
113             `configure', where FEATURE indicates an optional part of the package.
114             They may also pay attention to `--with-PACKAGE' options, where PACKAGE
115             is something like `gnu-as' or `x' (for the X Window System).  The
116             `README' should mention any `--enable-' and `--with-' options that the
117             package recognizes.
118             
119                For packages that use the X Window System, `configure' can usually
120             find the X include and library files automatically, but if it doesn't,
121             you can use the `configure' options `--x-includes=DIR' and
122             `--x-libraries=DIR' to specify their locations.
123             
124             Specifying the System Type
125             ==========================
126             
127 rizwank 1.1    There may be some features `configure' can not figure out
128             automatically, but needs to determine by the type of host the package
129             will run on.  Usually `configure' can figure that out, but if it prints
130             a message saying it can not guess the host type, give it the
131             `--host=TYPE' option.  TYPE can either be a short name for the system
132             type, such as `sun4', or a canonical name with three fields:
133                  CPU-COMPANY-SYSTEM
134             
135             See the file `config.sub' for the possible values of each field.  If
136             `config.sub' isn't included in this package, then this package doesn't
137             need to know the host type.
138             
139                If you are building compiler tools for cross-compiling, you can also
140             use the `--target=TYPE' option to select the type of system they will
141             produce code for and the `--build=TYPE' option to select the type of
142             system on which you are compiling the package.
143             
144             Sharing Defaults
145             ================
146             
147                If you want to set default values for `configure' scripts to share,
148 rizwank 1.1 you can create a site shell script called `config.site' that gives
149             default values for variables like `CC', `cache_file', and `prefix'.
150             `configure' looks for `PREFIX/share/config.site' if it exists, then
151             `PREFIX/etc/config.site' if it exists.  Or, you can set the
152             `CONFIG_SITE' environment variable to the location of the site script.
153             A warning: not all `configure' scripts look for a site script.
154             
155             Operation Controls
156             ==================
157             
158                `configure' recognizes the following options to control how it
159             operates.
160             
161             `--cache-file=FILE'
162                  Use and save the results of the tests in FILE instead of
163                  `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
164                  debugging `configure'.
165             
166             `--help'
167                  Print a summary of the options to `configure', and exit.
168             
169 rizwank 1.1 `--quiet'
170             `--silent'
171             `-q'
172                  Do not print messages saying which checks are being made.
173             
174             `--srcdir=DIR'
175                  Look for the package's source code in directory DIR.  Usually
176                  `configure' can determine that directory automatically.
177             
178             `--version'
179                  Print the version of Autoconf used to generate the `configure'
180                  script, and exit.
181             
182             `configure' also accepts some other, not widely useful, options.
183             
184             
185             Configuring Enscript to Your System
186             ===================================
187             
188             There are some options in enscript you might want to modify to meet
189             your system's needs.  You can change them all after the compilation by
190 rizwank 1.1 editing the global configuration file `enscript.cfg' at the directory
191             `PREFIX/etc/'.  You can also change some of the during the `configure'
192             step by giving the configure script appropriate options.  Please,
193             check the following things before reporting bugs; for the most cases
194             these help:
195             
196             * Paper size
197             
198               As a default enscript uses A4 paper.  To change default paper to be
199               for example `Letter', edit following line in the config file:
200             
201                 # Default output media.
202                 DefaultMedia: A4
203             
204                 => DefaultMedia: Letter
205             
206               You can also select the default paper size during the configuration
207               by giving the configure script option --with-media=MEDIA, where
208               media is one of the media listed in the `lib/enscript.cfg.in' file:
209               A3, A4, A5, Legal, Letter, A4dj or Letterdj.
210             
211 rizwank 1.1 * Default output device
212             
213               As a default (without any explicit options) enscript spools its
214               output to the printer.  If you want to send outputs to stdout, edit
215               following line:
216             
217                 # Where output goes as a default.
218                 DefaultOutputMethod: printer
219             
220                 => DefaultOutputMethod: stdout
221             
222             * Printer command
223             
224               Enscript's default printer command is `lpr'.  To change it to be for
225               example `lp', edit following line:
226             
227                 # Printer spooler command name.
228                 Spooler: lpr
229             
230                 => Spooler: lp
231             
232 rizwank 1.1   You can also set the spooler command during the configuration by
233               giving the configure script option `--with-spooler=SPOOLER'.
234             
235               On SystemV machines, you might also want to change the printer queue
236               name switch from `-P' to `-d':
237             
238                 # The spooler command switch to select the printer queue.
239                 QueueParam: -P
240             
241                 => QueueParam: -d
242             
243             * PostScript language level
244             
245               The PostScript language level that enscript uses for its output.
246               The default values is 2 (PostScript 2).  If your printer supports
247               only level 1 PostScript, you can set it to default by giving the
248               configure script option `--with-ps-level=1'.  You can also set the
249               level by editing the enscript.cfg file:
250             
251                 # The PostScript language level that enscript should use.
252                 PostScriptLevel: 2
253 rizwank 1.1 
254                 => PostScriptLevel: 1
255             
256               Or, you can select it at the print time with the `--ps-level=LEVEL'
257               option:
258             
259                 $ enscript --ps-level=1 ...
