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