10: Basic Installation
11: ==================
12:
13: These are generic installation instructions.
14:
15: The `configure' shell script attempts to guess correct values for
16: various system-dependent variables used during compilation. It uses
17: those values to create a `Makefile' in each directory of the package.
18: It may also create one or more `.h' files containing system-dependent
19: definitions. Finally, it creates a shell script `config.status' that
20: you can run in the future to recreate the current configuration, and a
21: file `config.log' containing compiler output (useful mainly for
22: debugging `configure').
23:
24: It can also use an optional file (typically called `config.cache'
25: and enabled with `--cache-file=config.cache' or simply `-C') that saves
26: the results of its tests to speed up reconfiguring. (Caching is
27: disabled by default to prevent problems with accidental use of stale
28: cache files.)
29:
30: If you need to do unusual things to compile the package, please try
31: to figure out how `configure' could check whether to do them, and mail
32: diffs or instructions to the address given in the `README' so they can
33: be considered for the next release. If you are using the cache, and at
34: some point `config.cache' contains results you don't want to keep, you
35: may 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
40: a newer version of `autoconf'.
41:
42: The 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:
70: Compilers and Options
71: =====================
72:
73: Some systems require unusual options for compilation or linking that the
74: `configure' script does not know about. Run `./configure --help' for
75: details on some of the pertinent environment variables.
76:
77: You can give `configure' initial values for configuration parameters
78: by setting variables in the command line or in the environment. Here
79: is an example:
80:
81: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
82:
83: *Note Defining Variables::, for more details.
84:
85: Compiling For Multiple Architectures
86: ====================================
87:
88: You can compile the package for more than one kind of computer at the
89: same time, by placing the object files for each architecture in their
90: own directory. To do this, you must use a version of `make' that
91: supports the `VPATH' variable, such as GNU `make'. `cd' to the
92: directory where you want the object files and executables to go and run
93: the `configure' script. `configure' automatically checks for the
94: source 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'
97: variable, you have to compile the package for one architecture at a
98: time in the source code directory. After you have installed the
99: package for one architecture, use `make distclean' before reconfiguring
100: for another architecture.
101:
102: Installation Names
103: ==================
104:
105: By default, `make install' installs the package's commands under
106: `/usr/local/bin', include files under `/usr/local/include', etc. You
107: can 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
111: architecture-specific files and architecture-independent files. If you
112: pass the option `--exec-prefix=PREFIX' to `configure', the package uses
113: PREFIX as the prefix for installing programs and libraries.
114: Documentation and other data files still use the regular prefix.
115:
116: In addition, if you use an unusual directory layout you can give
117: options like `--bindir=DIR' to specify different values for particular
118: kinds of files. Run `configure --help' for a list of the directories
119: you can set and what kinds of files go in them.
120:
121: If the package supports it, you can cause programs to be installed
122: with an extra prefix or suffix on their names by giving `configure' the
123: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
124:
125: Optional Features
126: =================
127:
128: Some packages pay attention to `--enable-FEATURE' options to
129: `configure', where FEATURE indicates an optional part of the package.
130: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
131: is something like `gnu-as' or `x' (for the X Window System). The
132: `README' should mention any `--enable-' and `--with-' options that the
133: package recognizes.
134:
135: For packages that use the X Window System, `configure' can usually
136: find the X include and library files automatically, but if it doesn't,
137: you can use the `configure' options `--x-includes=DIR' and
138: `--x-libraries=DIR' to specify their locations.
139:
140: Specifying the System Type
141: ==========================
142:
143: There may be some features `configure' cannot figure out automatically,
144: but needs to determine by the type of machine the package will run on.
145: Usually, assuming the package is built to be run on the _same_
146: architectures, `configure' can figure that out, but if it prints a
147: message saying it cannot guess the machine type, give it the
148: `--build=TYPE' option. TYPE can either be a short name for the system
149: type, such as `sun4', or a canonical name which has the form:
150:
151: CPU-COMPANY-SYSTEM
152:
153: where 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
159: need to know the machine type.
160:
161: If you are _building_ compiler tools for cross-compiling, you should
162: use the option `--target=TYPE' to select the type of system they will
163: produce code for.
164:
165: If you want to _use_ a cross compiler, that generates code for a
166: platform different from the build platform, you should specify the
167: "host" platform (i.e., that on which the generated programs will
168: eventually be run) with `--host=TYPE'.
169:
170: Sharing Defaults
171: ================
172:
173: If you want to set default values for `configure' scripts to share, you
174: can create a site shell script called `config.site' that gives default
175: values 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.
179: A warning: not all `configure' scripts look for a site script.
180:
181: Defining Variables
182: ==================
183:
184: Variables not defined in a site shell script can be set in the
185: environment passed to `configure'. However, some packages may run
186: configure again during the build, and the customized values of these
187: variables may be lost. In order to avoid this problem, you should set
188: them in the `configure' command line, using `VAR=value'. For example:
189:
190: ./configure CC=/usr/local2/bin/gcc
191:
192: causes the specified `gcc' to be used as the C compiler (unless it is
193: overridden in the site shell script). Here is a another example:
194:
195: /bin/bash ./configure CONFIG_SHELL=/bin/bash
196:
197: Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
198: configuration-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.
