These are generic installation instructions.
12
The `configure' shell script attempts to guess correct values for
13
various system-dependent variables used during compilation. It uses
14
those values to create a `Makefile' in each directory of the package.
15
It may also create one or more `.h' files containing system-dependent
16
definitions. Finally, it creates a shell script `config.status' that
17
you can run in the future to recreate the current configuration, and a
18
file `config.log' containing compiler output (useful mainly for
19
debugging `configure').
21
It can also use an optional file (typically called `config.cache'
22
and enabled with `--cache-file=config.cache' or simply `-C') that saves
23
the results of its tests to speed up reconfiguring. (Caching is
24
disabled by default to prevent problems with accidental use of stale
27
If you need to do unusual things to compile the package, please try
28
to figure out how `configure' could check whether to do them, and mail
29
diffs or instructions to the address given in the `README' so they can
30
be considered for the next release. If you are using the cache, and at
31
some point `config.cache' contains results you don't want to keep, you
32
may remove or edit it.
34
The file `configure.ac' (or `configure.in') is used to create
35
`configure' by a program called `autoconf'. You only need
36
`configure.ac' if you want to change it or regenerate `configure' using
37
a newer version of `autoconf'.
39
The simplest way to compile this package is:
41
1. `cd' to the directory containing the package's source code and type
42
`./configure' to configure the package for your system. If you're
43
using `csh' on an old version of System V, you might need to type
44
`sh ./configure' instead to prevent `csh' from trying to execute
47
Running `configure' takes awhile. While running, it prints some
48
messages telling which features it is checking for.
50
2. Type `make' to compile the package.
52
3. Optionally, type `make check' to run any self-tests that come with
55
4. Type `make install' to install the programs and any data files and
58
5. You can remove the program binaries and object files from the
59
source code directory by typing `make clean'. To also remove the
60
files that `configure' created (so you can compile the package for
61
a different kind of computer), type `make distclean'. There is
62
also a `make maintainer-clean' target, but that is intended mainly
63
for the package's developers. If you use it, you may have to get
64
all sorts of other programs in order to regenerate files that came
65
with the distribution.
70
Some systems require unusual options for compilation or linking that
71
the `configure' script does not know about. Run `./configure --help'
72
for details on some of the pertinent environment variables.
74
You can give `configure' initial values for variables by setting
75
them in the environment. You can do that on the command line like this:
77
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
79

81
Compiling For Multiple Architectures
82
====================================
84
You can compile the package for more than one kind of computer at the
85
same time, by placing the object files for each architecture in their
86
own directory. To do this, you must use a version of `make' that
87
supports the `VPATH' variable, such as GNU `make'. `cd' to the
88
directory where you want the object files and executables to go and run
89
the `configure' script. `configure' automatically checks for the
90
source code in the directory that `configure' is in and in `..'.
92
If you have to use a `make' that does not support the `VPATH'
93
variable, you have to compile the package for one architecture at a
94
time in the source code directory. After you have installed the
95
package for one architecture, use `make distclean' before reconfiguring
96
for another architecture.
101
By default, `make install' will install the package's files in
102
`/usr/local/bin', `/usr/local/man', etc. You can specify an
103
installation prefix other than `/usr/local' by giving `configure' the
104
option `--prefix=PATH'.
106
You can specify separate installation prefixes for
107
architecture-specific files and architecture-independent files. If you
108
give `configure' the option `--exec-prefix=PATH', the package will use
109
PATH as the prefix for installing programs and libraries.
110
Documentation and other data files will still use the regular prefix.
112
In addition, if you use an unusual directory layout you can give
113
options like `--bindir=PATH' to specify different values for particular
114
kinds of files. Run `configure --help' for a list of the directories
115
you can set and what kinds of files go in them.
117
If the package supports it, you can cause programs to be installed
118
with an extra prefix or suffix on their names by giving `configure' the
119
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
124
Some packages pay attention to `--enable-FEATURE' options to
125
`configure', where FEATURE indicates an optional part of the package.
126
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
127
is something like `gnu-as' or `x' (for the X Window System). The
128
`README' should mention any `--enable-' and `--with-' options that the
131
For packages that use the X Window System, `configure' can usually
132
find the X include and library files automatically, but if it doesn't,
133
you can use the `configure' options `--x-includes=DIR' and
134
`--x-libraries=DIR' to specify their locations.
136
Specifying the System Type
137
==========================
139
There may be some features `configure' cannot figure out
140
automatically, but needs to determine by the type of host the package
141
will run on. Usually `configure' can figure that out, but if it prints
142
a message saying it cannot guess the host type, give it the
143
`--build=TYPE' option. TYPE can either be a short name for the system
144
type, such as `sun4', or a canonical name which has the form:
148
where SYSTEM can have one of these forms:
152
See the file `config.sub' for the possible values of each field. If
153
`config.sub' isn't included in this package, then this package doesn't
154
need to know the host type.
156
If you are _building_ compiler tools for cross-compiling, you should
157
use the `--target=TYPE' option to select the type of system they will
160
If you want to _use_ a cross compiler, that generates code for a
161
platform different from the build platform, you should specify the host
162
platform (i.e., that on which the generated programs will eventually be
163
run) with `--host=TYPE'. In this case, you should also specify the
164
build platform with `--build=TYPE', because, in this case, it may not
165
be possible to guess the build platform (it sometimes involves
166
compiling and running simple test programs, and this can't be done if
167
the compiler is a cross compiler).
172
If you want to set default values for `configure' scripts to share,
173
you can create a site shell script called `config.site' that gives
174
default values for variables like `CC', `cache_file', and `prefix'.
175
`configure' looks for `PREFIX/share/config.site' if it exists, then
176
`PREFIX/etc/config.site' if it exists. Or, you can set the
177
`CONFIG_SITE' environment variable to the location of the site script.
178
A warning: not all `configure' scripts look for a site script.
183
Variables not defined in a site shell script can be set in the
184
environment passed to `configure'. However, some packages may run
185
configure again during the build, and the customized values of these
186
variables may be lost. In order to avoid this problem, you should set
187
them in the `configure' command line, using `VAR=value'. For example:
189
./configure CC=/usr/local2/bin/gcc
191
will cause the specified gcc to be used as the C compiler (unless it is
192
overridden in the site shell script).
194
`configure' Invocation
195
======================
197
`configure' recognizes the following options to control how it
202
Print a summary of the options to `configure', and exit.
206
Print the version of Autoconf used to generate the `configure'
210
Enable the cache: use and save the results of the tests in FILE,
211
traditionally `config.cache'. FILE defaults to `/dev/null' to
216
Alias for `--cache-file=config.cache'.
221
Do not print messages saying which checks are being made. To
222
suppress all normal output, redirect it to `/dev/null' (any error
223
messages will still be shown).
226
Look for the package's source code in directory DIR. Usually
227
`configure' can determine that directory automatically.
229
`configure' also accepts some other, not widely useful, options. Run
230
`configure --help' for more details.
