 10Basic Installation
 11==================
 12
 13These are generic installation instructions.
 14
 15   The `configure' shell script attempts to guess correct values for
 16various system-dependent variables used during compilation.  It uses
 17those values to create a `Makefile' in each directory of the package.
 18It may also create one or more `.h' files containing system-dependent
 19definitions.  Finally, it creates a shell script `config.status' that
 20you can run in the future to recreate the current configuration, and a
 21file `config.log' containing compiler output (useful mainly for
 22debugging `configure').
 23
 24   It can also use an optional file (typically called `config.cache'
 25and enabled with `--cache-file=config.cache' or simply `-C') that saves
 26the results of its tests to speed up reconfiguring.  (Caching is
 27disabled by default to prevent problems with accidental use of stale
 28cache files.)
 29
 30   If you need to do unusual things to compile the package, please try
 31to figure out how `configure' could check whether to do them, and mail
 32diffs or instructions to the address given in the `README' so they can
 33be considered for the next release.  If you are using the cache, and at
 34some point `config.cache' contains results you don't want to keep, you
 35may remove or edit it.
 36
 37   The file `configure.ac' (or `configure.in') is used to create
 38`configure' by a program called `autoconf'.  You only need
 39`configure.ac' if you want to change it or regenerate `configure' using
 40a newer version of `autoconf'.
 41
 42The simplest way to compile this package is:
 43
 44  1. `cd' to the directory containing the package's source code and type
 45     `./configure' to configure the package for your system.  If you're
 46     using `csh' on an old version of System V, you might need to type
 47     `sh ./configure' instead to prevent `csh' from trying to execute
 48     `configure' itself.
 49
 50     Running `configure' takes awhile.  While running, it prints some
 51     messages telling which features it is checking for.
 52
 53  2. Type `make' to compile the package.
 54
 55  3. Optionally, type `make check' to run any self-tests that come with
 56     the package.
 57
 58  4. Type `make install' to install the programs and any data files and
 59     documentation.
 60
 61  5. You can remove the program binaries and object files from the
 62     source code directory by typing `make clean'.  To also remove the
 63     files that `configure' created (so you can compile the package for
 64     a different kind of computer), type `make distclean'.  There is
 65     also a `make maintainer-clean' target, but that is intended mainly
 66     for the package's developers.  If you use it, you may have to get
 67     all sorts of other programs in order to regenerate files that came
 68     with the distribution.
 69
 70Compilers and Options
 71=====================
 72
 73Some systems require unusual options for compilation or linking that the
 74`configure' script does not know about.  Run `./configure --help' for
 75details on some of the pertinent environment variables.
 76
 77   You can give `configure' initial values for configuration parameters
 78by setting variables in the command line or in the environment.  Here
 79is an example:
 80
 81     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
 82
 83   *Note Defining Variables::, for more details.
 84
 85Compiling For Multiple Architectures
 86====================================
 87
 88You can compile the package for more than one kind of computer at the
 89same time, by placing the object files for each architecture in their
 90own directory.  To do this, you must use a version of `make' that
 91supports the `VPATH' variable, such as GNU `make'.  `cd' to the
 92directory where you want the object files and executables to go and run
 93the `configure' script.  `configure' automatically checks for the
 94source code in the directory that `configure' is in and in `..'.
 95
 96   If you have to use a `make' that does not support the `VPATH'
 97variable, you have to compile the package for one architecture at a
 98time in the source code directory.  After you have installed the
 99package for one architecture, use `make distclean' before reconfiguring
100for another architecture.
101
102Installation Names
103==================
104
105By default, `make install' installs the package's commands under
106`/usr/local/bin', include files under `/usr/local/include', etc.  You
107can specify an installation prefix other than `/usr/local' by giving
108`configure' the option `--prefix=PREFIX'.
109
110   You can specify separate installation prefixes for
111architecture-specific files and architecture-independent files.  If you
112pass the option `--exec-prefix=PREFIX' to `configure', the package uses
113PREFIX as the prefix for installing programs and libraries.
114Documentation and other data files still use the regular prefix.
115
116   In addition, if you use an unusual directory layout you can give
117options like `--bindir=DIR' to specify different values for particular
118kinds of files.  Run `configure --help' for a list of the directories
119you can set and what kinds of files go in them.
120
121   If the package supports it, you can cause programs to be installed
122with an extra prefix or suffix on their names by giving `configure' the
123option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
124
125Optional Features
126=================
127
128Some packages pay attention to `--enable-FEATURE' options to
129`configure', where FEATURE indicates an optional part of the package.
130They may also pay attention to `--with-PACKAGE' options, where PACKAGE
131is something like `gnu-as' or `x' (for the X Window System).  The
132`README' should mention any `--enable-' and `--with-' options that the
133package recognizes.
134
135   For packages that use the X Window System, `configure' can usually
136find the X include and library files automatically, but if it doesn't,
137you can use the `configure' options `--x-includes=DIR' and
138`--x-libraries=DIR' to specify their locations.
139
140Specifying the System Type
141==========================
142
143There may be some features `configure' cannot figure out automatically,
144but needs to determine by the type of machine the package will run on.
145Usually, assuming the package is built to be run on the _same_
146architectures, `configure' can figure that out, but if it prints a
147message saying it cannot guess the machine type, give it the
148`--build=TYPE' option.  TYPE can either be a short name for the system
149type, such as `sun4', or a canonical name which has the form:
150
151     CPU-COMPANY-SYSTEM
152
153where SYSTEM can have one of these forms:
154
155     OS KERNEL-OS
156
157   See the file `config.sub' for the possible values of each field.  If
158`config.sub' isn't included in this package, then this package doesn't
159need to know the machine type.
160
161   If you are _building_ compiler tools for cross-compiling, you should
162use the option `--target=TYPE' to select the type of system they will
163produce code for.
164
165   If you want to _use_ a cross compiler, that generates code for a
166platform different from the build platform, you should specify the
167"host" platform (i.e., that on which the generated programs will
168eventually be run) with `--host=TYPE'.
169
170Sharing Defaults
171================
172
173If you want to set default values for `configure' scripts to share, you
174can create a site shell script called `config.site' that gives default
175values for variables like `CC', `cache_file', and `prefix'.
176`configure' looks for `PREFIX/share/config.site' if it exists, then
177`PREFIX/etc/config.site' if it exists.  Or, you can set the
178`CONFIG_SITE' environment variable to the location of the site script.
179A warning: not all `configure' scripts look for a site script.
180
181Defining Variables
182==================
183
184Variables not defined in a site shell script can be set in the
185environment passed to `configure'.  However, some packages may run
186configure again during the build, and the customized values of these
187variables may be lost.  In order to avoid this problem, you should set
188them in the `configure' command line, using `VAR=value'.  For example:
189
190     ./configure CC=/usr/local2/bin/gcc
191
192causes the specified `gcc' to be used as the C compiler (unless it is
193overridden in the site shell script).  Here is a another example:
194
195     /bin/bash ./configure CONFIG_SHELL=/bin/bash
196
197Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
198configuration-related scripts to be executed by `/bin/bash'.
199
200`configure' Invocation
201======================
202
203`configure' recognizes the following options to control how it operates.
204
205`--help'
206`-h'
207     Print a summary of the options to `configure', and exit.
208
209`--version'
210`-V'
211     Print the version of Autoconf used to generate the `configure'
212     script, and exit.
213
214`--cache-file=FILE'
215     Enable the cache: use and save the results of the tests in FILE,
216     traditionally `config.cache'.  FILE defaults to `/dev/null' to
217     disable caching.
218
219`--config-cache'
220`-C'
221     Alias for `--cache-file=config.cache'.
222
223`--quiet'
224`--silent'
225`-q'
226     Do not print messages saying which checks are being made.  To
227     suppress all normal output, redirect it to `/dev/null' (any error
228     messages will still be shown).
229
230`--srcdir=DIR'
231     Look for the package's source code in directory DIR.  Usually
232     `configure' can determine that directory automatically.
233
234`configure' also accepts some other, not widely useful, options.  Run
235`configure --help' for more details.
