10: Basic Installation
11: ==================
12:
13: Briefly, the shell commands `./configure; make; make install' should
14: configure, build, and install this package. The following
15: more-detailed instructions are generic; see the `README' file for
16: instructions specific to this package.
17:
18: The `configure' shell script attempts to guess correct values for
19: various system-dependent variables used during compilation. It uses
20: those values to create a `Makefile' in each directory of the package.
21: It may also create one or more `.h' files containing system-dependent
22: definitions. Finally, it creates a shell script `config.status' that
23: you can run in the future to recreate the current configuration, and a
24: file `config.log' containing compiler output (useful mainly for
25: debugging `configure').
26:
27: It can also use an optional file (typically called `config.cache'
28: and enabled with `--cache-file=config.cache' or simply `-C') that saves
29: the results of its tests to speed up reconfiguring. Caching is
30: disabled by default to prevent problems with accidental use of stale
31: cache files.
32:
33: If you need to do unusual things to compile the package, please try
34: to figure out how `configure' could check whether to do them, and mail
35: diffs or instructions to the address given in the `README' so they can
36: be considered for the next release. If you are using the cache, and at
37: some point `config.cache' contains results you don't want to keep, you
38: may remove or edit it.
39:
40: The file `configure.ac' (or `configure.in') is used to create
41: `configure' by a program called `autoconf'. You need `configure.ac' if
42: you want to change it or regenerate `configure' using a newer version
43: of `autoconf'.
44:
45: The simplest way to compile this package is:
46:
47: 1. `cd' to the directory containing the package's source code and type
48: `./configure' to configure the package for your system.
49:
50: Running `configure' might take a while. While running, it prints
51: some 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: 6. Often, you can also type `make uninstall' to remove the installed
71: files again.
72:
73: Compilers and Options
74: =====================
75:
76: Some systems require unusual options for compilation or linking that the
77: `configure' script does not know about. Run `./configure --help' for
78: details on some of the pertinent environment variables.
79:
80: You can give `configure' initial values for configuration parameters
81: by setting variables in the command line or in the environment. Here
82: is an example:
83:
84: ./configure CC=c99 CFLAGS=-g LIBS=-lposix
85:
86: *Note Defining Variables::, for more details.
87:
88: Compiling For Multiple Architectures
89: ====================================
90:
91: You can compile the package for more than one kind of computer at the
92: same time, by placing the object files for each architecture in their
93: own directory. To do this, you can use GNU `make'. `cd' to the
94: directory where you want the object files and executables to go and run
95: the `configure' script. `configure' automatically checks for the
96: source code in the directory that `configure' is in and in `..'.
97:
98: With a non-GNU `make', it is safer to compile the package for one
99: architecture at a time in the source code directory. After you have
100: installed the package for one architecture, use `make distclean' before
101: reconfiguring for another architecture.
102:
103: Installation Names
104: ==================
105:
106: By default, `make install' installs the package's commands under
107: `/usr/local/bin', include files under `/usr/local/include', etc. You
108: can specify an installation prefix other than `/usr/local' by giving
109: `configure' the option `--prefix=PREFIX'.
110:
111: You can specify separate installation prefixes for
112: architecture-specific files and architecture-independent files. If you
113: pass the option `--exec-prefix=PREFIX' to `configure', the package uses
114: PREFIX as the prefix for installing programs and libraries.
115: Documentation and other data files still use the regular prefix.
116:
117: In addition, if you use an unusual directory layout you can give
118: options like `--bindir=DIR' to specify different values for particular
119: kinds of files. Run `configure --help' for a list of the directories
120: you can set and what kinds of files go in them.
121:
122: If the package supports it, you can cause programs to be installed
123: with an extra prefix or suffix on their names by giving `configure' the
124: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
125:
126: Optional Features
127: =================
128:
129: Some packages pay attention to `--enable-FEATURE' options to
130: `configure', where FEATURE indicates an optional part of the package.
131: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
132: is something like `gnu-as' or `x' (for the X Window System). The
133: `README' should mention any `--enable-' and `--with-' options that the
134: package recognizes.
135:
136: For packages that use the X Window System, `configure' can usually
137: find the X include and library files automatically, but if it doesn't,
138: you can use the `configure' options `--x-includes=DIR' and
139: `--x-libraries=DIR' to specify their locations.
140:
141: Specifying the System Type
142: ==========================
143:
144: There may be some features `configure' cannot figure out automatically,
145: but needs to determine by the type of machine the package will run on.
146: Usually, assuming the package is built to be run on the _same_
147: architectures, `configure' can figure that out, but if it prints a
148: message saying it cannot guess the machine type, give it the
149: `--build=TYPE' option. TYPE can either be a short name for the system
150: type, such as `sun4', or a canonical name which has the form:
151:
152: CPU-COMPANY-SYSTEM
153:
154: where SYSTEM can have one of these forms:
155:
156: OS KERNEL-OS
157:
158: See the file `config.sub' for the possible values of each field. If
159: `config.sub' isn't included in this package, then this package doesn't
160: need to know the machine type.
161:
162: If you are _building_ compiler tools for cross-compiling, you should
163: use the option `--target=TYPE' to select the type of system they will
164: produce code for.
165:
166: If you want to _use_ a cross compiler, that generates code for a
167: platform different from the build platform, you should specify the
168: "host" platform (i.e., that on which the generated programs will
169: eventually be run) with `--host=TYPE'.
170:
171: Sharing Defaults
172: ================
173:
174: If you want to set default values for `configure' scripts to share, you
175: can create a site shell script called `config.site' that gives default
176: values for variables like `CC', `cache_file', and `prefix'.
177: `configure' looks for `PREFIX/share/config.site' if it exists, then
178: `PREFIX/etc/config.site' if it exists. Or, you can set the
179: `CONFIG_SITE' environment variable to the location of the site script.
180: A warning: not all `configure' scripts look for a site script.
181:
182: Defining Variables
183: ==================
184:
185: Variables not defined in a site shell script can be set in the
186: environment passed to `configure'. However, some packages may run
187: configure again during the build, and the customized values of these
188: variables may be lost. In order to avoid this problem, you should set
189: them in the `configure' command line, using `VAR=value'. For example:
190:
191: ./configure CC=/usr/local2/bin/gcc
192:
193: causes the specified `gcc' to be used as the C compiler (unless it is
194: overridden in the site shell script).
195:
196: Unfortunately, this technique does not work for `CONFIG_SHELL' due to
197: an Autoconf bug. Until the bug is fixed you can use this workaround:
198:
199: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
200:
201: `configure' Invocation
202: ======================
203:
204: `configure' recognizes the following options to control how it operates.
205:
206: `--help'
207: `-h'
208: Print a summary of the options to `configure', and exit.
209:
210: `--version'
211: `-V'
212: Print the version of Autoconf used to generate the `configure'
213: script, and exit.
214:
215: `--cache-file=FILE'
216: Enable the cache: use and save the results of the tests in FILE,
217: traditionally `config.cache'. FILE defaults to `/dev/null' to
218: disable caching.
219:
220: `--config-cache'
221: `-C'
222: Alias for `--cache-file=config.cache'.
223:
224: `--quiet'
225: `--silent'
226: `-q'
227: Do not print messages saying which checks are being made. To
228: suppress all normal output, redirect it to `/dev/null' (any error
229: messages will still be shown).
230:
231: `--srcdir=DIR'
232: Look for the package's source code in directory DIR. Usually
233: `configure' can determine that directory automatically.
234:
235: `configure' also accepts some other, not widely useful, options. Run
236: `configure --help' for more details.
