42 Recent development is with GNU/Linux. I have tested compilation on
43 FreeBSD v4.0, BSD/OS v3.0, and Solaris v8.
49 These are generic installation instructions.
51 The `configure' shell script attempts to guess correct values for
52 various system-dependent variables used during compilation. It uses
53 those values to create a `Makefile' in each directory of the package.
54 It may also create one or more `.h' files containing system-dependent
55 definitions. Finally, it creates a shell script `config.status' that
56 you can run in the future to recreate the current configuration, a file
57 `config.cache' that saves the results of its tests to speed up
58 reconfiguring, and a file `config.log' containing compiler output
59 (useful mainly for debugging `configure').
61 If you need to do unusual things to compile the package, please try
62 to figure out how `configure' could check whether to do them, and mail
63 diffs or instructions to the address given in the `README' so they can
64 be considered for the next release. If at some point `config.cache'
65 contains results you don't want to keep, you may remove or edit it.
67 The file `configure.in' is used to create `configure' by a program
68 called `autoconf'. You only need `configure.in' if you want to change
69 it or regenerate `configure' using a newer version of `autoconf'.
71 The simplest way to compile this package is:
73 1. `cd' to the directory containing the package's source code and type
74 `./configure' to configure the package for your system. If you're
75 using `csh' on an old version of System V, you might need to type
76 `sh ./configure' instead to prevent `csh' from trying to execute
79 Running `configure' takes awhile. While running, it prints some
80 messages telling which features it is checking for.
82 2. Type `make' to compile the package.
84 3. Optionally, type `make check' to run any self-tests that come with
87 4. Type `make install' to install the programs and any data files and
90 5. You can remove the program binaries and object files from the
91 source code directory by typing `make clean'. To also remove the
92 files that `configure' created (so you can compile the package for
93 a different kind of computer), type `make distclean'. There is
94 also a `make maintainer-clean' target, but that is intended mainly
95 for the package's developers. If you use it, you may have to get
96 all sorts of other programs in order to regenerate files that came
97 with the distribution.
100 =====================
102 Some systems require unusual options for compilation or linking that
103 the `configure' script does not know about. You can give `configure'
104 initial values for variables by setting them in the environment. Using
105 a Bourne-compatible shell, you can do that on the command line like
107 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
109 Or on systems that have the `env' program, you can do it like this:
110 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
112 Compiling For Multiple Architectures
113 ====================================
115 You can compile the package for more than one kind of computer at the
116 same time, by placing the object files for each architecture in their
117 own directory. To do this, you must use a version of `make' that
118 supports the `VPATH' variable, such as GNU `make'. `cd' to the
119 directory where you want the object files and executables to go and run
120 the `configure' script. `configure' automatically checks for the
121 source code in the directory that `configure' is in and in `..'.
123 If you have to use a `make' that does not supports the `VPATH'
124 variable, you have to compile the package for one architecture at a time
125 in the source code directory. After you have installed the package for
126 one architecture, use `make distclean' before reconfiguring for another
132 By default, `make install' will install the package's files in
133 `/usr/local/bin', `/usr/local/man', etc. You can specify an
134 installation prefix other than `/usr/local' by giving `configure' the
135 option `--prefix=PATH'.
137 You can specify separate installation prefixes for
138 architecture-specific files and architecture-independent files. If you
139 give `configure' the option `--exec-prefix=PATH', the package will use
140 PATH as the prefix for installing programs and libraries.
141 Documentation and other data files will still use the regular prefix.
143 In addition, if you use an unusual directory layout you can give
144 options like `--bindir=PATH' to specify different values for particular
145 kinds of files. Run `configure --help' for a list of the directories
146 you can set and what kinds of files go in them.
148 If the package supports it, you can cause programs to be installed
149 with an extra prefix or suffix on their names by giving `configure' the
150 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
155 Some packages pay attention to `--enable-FEATURE' options to
156 `configure', where FEATURE indicates an optional part of the package.
157 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
158 is something like `gnu-as' or `x' (for the X Window System). The
159 `README' should mention any `--enable-' and `--with-' options that the
162 For packages that use the X Window System, `configure' can usually
163 find the X include and library files automatically, but if it doesn't,
164 you can use the `configure' options `--x-includes=DIR' and
165 `--x-libraries=DIR' to specify their locations.
167 Specifying the System Type
168 ==========================
170 There may be some features `configure' can not figure out
171 automatically, but needs to determine by the type of host the package
172 will run on. Usually `configure' can figure that out, but if it prints
173 a message saying it can not guess the host type, give it the
174 `--host=TYPE' option. TYPE can either be a short name for the system
175 type, such as `sun4', or a canonical name with three fields:
178 See the file `config.sub' for the possible values of each field. If
179 `config.sub' isn't included in this package, then this package doesn't
180 need to know the host type.
182 If you are building compiler tools for cross-compiling, you can also
183 use the `--target=TYPE' option to select the type of system they will
184 produce code for and the `--build=TYPE' option to select the type of
185 system on which you are compiling the package.
190 If you want to set default values for `configure' scripts to share,
191 you can create a site shell script called `config.site' that gives
192 default values for variables like `CC', `cache_file', and `prefix'.
193 `configure' looks for `PREFIX/share/config.site' if it exists, then
194 `PREFIX/etc/config.site' if it exists. Or, you can set the
195 `CONFIG_SITE' environment variable to the location of the site script.
196 A warning: not all `configure' scripts look for a site script.
201 `configure' recognizes the following options to control how it
205 Use and save the results of the tests in FILE instead of
206 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
207 debugging `configure'.
210 Print a summary of the options to `configure', and exit.
215 Do not print messages saying which checks are being made. To
216 suppress all normal output, redirect it to `/dev/null' (any error
217 messages will still be shown).
220 Look for the package's source code in directory DIR. Usually
221 `configure' can determine that directory automatically.
224 Print the version of Autoconf used to generate the `configure'
227 `configure' also accepts some other, not widely useful, options.
