1.10 +Basic Installation
1.11 +==================
1.12 +
1.13 + These are generic installation instructions.
1.14 +
1.15 + The `configure' shell script attempts to guess correct values for
1.16 +various system-dependent variables used during compilation. It uses
1.17 +those values to create a `Makefile' in each directory of the package.
1.18 +It may also create one or more `.h' files containing system-dependent
1.19 +definitions. Finally, it creates a shell script `config.status' that
1.20 +you can run in the future to recreate the current configuration, and a
1.21 +file `config.log' containing compiler output (useful mainly for
1.22 +debugging `configure').
1.23 +
1.24 + It can also use an optional file (typically called `config.cache'
1.25 +and enabled with `--cache-file=config.cache' or simply `-C') that saves
1.26 +the results of its tests to speed up reconfiguring. (Caching is
1.27 +disabled by default to prevent problems with accidental use of stale
1.28 +cache files.)
1.29 +
1.30 + If you need to do unusual things to compile the package, please try
1.31 +to figure out how `configure' could check whether to do them, and mail
1.32 +diffs or instructions to the address given in the `README' so they can
1.33 +be considered for the next release. If you are using the cache, and at
1.34 +some point `config.cache' contains results you don't want to keep, you
1.35 +may remove or edit it.
1.36 +
1.37 + The file `configure.ac' (or `configure.in') is used to create
1.38 +`configure' by a program called `autoconf'. You only need
1.39 +`configure.ac' if you want to change it or regenerate `configure' using
1.40 +a newer version of `autoconf'.
1.41 +
1.42 +The simplest way to compile this package is:
1.43 +
1.44 + 1. `cd' to the directory containing the package's source code and type
1.45 + `./configure' to configure the package for your system. If you're
1.46 + using `csh' on an old version of System V, you might need to type
1.47 + `sh ./configure' instead to prevent `csh' from trying to execute
1.48 + `configure' itself.
1.49 +
1.50 + Running `configure' takes awhile. While running, it prints some
1.51 + messages telling which features it is checking for.
1.52 +
1.53 + 2. Type `make' to compile the package.
1.54 +
1.55 + 3. Optionally, type `make check' to run any self-tests that come with
1.56 + the package.
1.57 +
1.58 + 4. Type `make install' to install the programs and any data files and
1.59 + documentation.
1.60 +
1.61 + 5. You can remove the program binaries and object files from the
1.62 + source code directory by typing `make clean'. To also remove the
1.63 + files that `configure' created (so you can compile the package for
1.64 + a different kind of computer), type `make distclean'. There is
1.65 + also a `make maintainer-clean' target, but that is intended mainly
1.66 + for the package's developers. If you use it, you may have to get
1.67 + all sorts of other programs in order to regenerate files that came
1.68 + with the distribution.
1.69 +
1.70 +Compilers and Options
1.71 +=====================
1.72 +
1.73 + Some systems require unusual options for compilation or linking that
1.74 +the `configure' script does not know about. Run `./configure --help'
1.75 +for details on some of the pertinent environment variables.
1.76 +
1.77 + You can give `configure' initial values for configuration parameters
1.78 +by setting variables in the command line or in the environment. Here
1.79 +is an example:
1.80 +
1.81 + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
1.82 +
1.83 + *Note Defining Variables::, for more details.
1.84 +
1.85 +Compiling For Multiple Architectures
1.86 +====================================
1.87 +
1.88 + You can compile the package for more than one kind of computer at the
1.89 +same time, by placing the object files for each architecture in their
1.90 +own directory. To do this, you must use a version of `make' that
1.91 +supports the `VPATH' variable, such as GNU `make'. `cd' to the
1.92 +directory where you want the object files and executables to go and run
1.93 +the `configure' script. `configure' automatically checks for the
1.94 +source code in the directory that `configure' is in and in `..'.
1.95 +
1.96 + If you have to use a `make' that does not support the `VPATH'
1.97 +variable, you have to compile the package for one architecture at a
1.98 +time in the source code directory. After you have installed the
1.99 +package for one architecture, use `make distclean' before reconfiguring
1.100 +for another architecture.
1.101 +
1.102 +Installation Names
1.103 +==================
1.104 +
1.105 + By default, `make install' will install the package's files in
1.106 +`/usr/local/bin', `/usr/local/man', etc. You can specify an
1.107 +installation prefix other than `/usr/local' by giving `configure' the
1.108 +option `--prefix=PATH'.
1.109 +
1.110 + You can specify separate installation prefixes for
1.111 +architecture-specific files and architecture-independent files. If you
1.112 +give `configure' the option `--exec-prefix=PATH', the package will use
1.113 +PATH as the prefix for installing programs and libraries.
1.114 +Documentation and other data files will still use the regular prefix.
1.115 +
1.116 + In addition, if you use an unusual directory layout you can give
1.117 +options like `--bindir=PATH' to specify different values for particular
1.118 +kinds of files. Run `configure --help' for a list of the directories
1.119 +you can set and what kinds of files go in them.
1.120 +
1.121 + If the package supports it, you can cause programs to be installed
1.122 +with an extra prefix or suffix on their names by giving `configure' the
1.123 +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
1.124 +
1.125 +Optional Features
1.126 +=================
1.127 +
1.128 + Some packages pay attention to `--enable-FEATURE' options to
1.129 +`configure', where FEATURE indicates an optional part of the package.
1.130 +They may also pay attention to `--with-PACKAGE' options, where PACKAGE
1.131 +is something like `gnu-as' or `x' (for the X Window System). The
1.132 +`README' should mention any `--enable-' and `--with-' options that the
1.133 +package recognizes.
1.134 +
1.135 + For packages that use the X Window System, `configure' can usually
1.136 +find the X include and library files automatically, but if it doesn't,
1.137 +you can use the `configure' options `--x-includes=DIR' and
1.138 +`--x-libraries=DIR' to specify their locations.
1.139 +
1.140 +Specifying the System Type
1.141 +==========================
1.142 +
1.143 + There may be some features `configure' cannot figure out
1.144 +automatically, but needs to determine by the type of machine the package
1.145 +will run on. Usually, assuming the package is built to be run on the
1.146 +_same_ architectures, `configure' can figure that out, but if it prints
1.147 +a message saying it cannot guess the machine type, give it the
1.148 +`--build=TYPE' option. TYPE can either be a short name for the system
1.149 +type, such as `sun4', or a canonical name which has the form:
1.150 +
1.151 + CPU-COMPANY-SYSTEM
1.152 +
1.153 +where SYSTEM can have one of these forms:
1.154 +
1.155 + OS KERNEL-OS
1.156 +
1.157 + See the file `config.sub' for the possible values of each field. If
1.158 +`config.sub' isn't included in this package, then this package doesn't
1.159 +need to know the machine type.
1.160 +
1.161 + If you are _building_ compiler tools for cross-compiling, you should
1.162 +use the `--target=TYPE' option to select the type of system they will
1.163 +produce code for.
1.164 +
1.165 + If you want to _use_ a cross compiler, that generates code for a
1.166 +platform different from the build platform, you should specify the
1.167 +"host" platform (i.e., that on which the generated programs will
1.168 +eventually be run) with `--host=TYPE'.
1.169 +
1.170 +Sharing Defaults
1.171 +================
1.172 +
1.173 + If you want to set default values for `configure' scripts to share,
1.174 +you can create a site shell script called `config.site' that gives
1.175 +default values for variables like `CC', `cache_file', and `prefix'.
1.176 +`configure' looks for `PREFIX/share/config.site' if it exists, then
1.177 +`PREFIX/etc/config.site' if it exists. Or, you can set the
1.178 +`CONFIG_SITE' environment variable to the location of the site script.
1.179 +A warning: not all `configure' scripts look for a site script.
1.180 +
1.181 +Defining Variables
1.182 +==================
1.183 +
1.184 + Variables not defined in a site shell script can be set in the
1.185 +environment passed to `configure'. However, some packages may run
1.186 +configure again during the build, and the customized values of these
1.187 +variables may be lost. In order to avoid this problem, you should set
1.188 +them in the `configure' command line, using `VAR=value'. For example:
1.189 +
1.190 + ./configure CC=/usr/local2/bin/gcc
1.191 +
1.192 +will cause the specified gcc to be used as the C compiler (unless it is
1.193 +overridden in the site shell script).
1.194 +
1.195 +`configure' Invocation
1.196 +======================
1.197 +
1.198 + `configure' recognizes the following options to control how it
1.199 +operates.
1.200 +
1.201 +`--help'
1.202 +`-h'
1.203 + Print a summary of the options to `configure', and exit.
1.204 +
1.205 +`--version'
1.206 +`-V'
1.207 + Print the version of Autoconf used to generate the `configure'
1.208 + script, and exit.
1.209 +
1.210 +`--cache-file=FILE'
1.211 + Enable the cache: use and save the results of the tests in FILE,
1.212 + traditionally `config.cache'. FILE defaults to `/dev/null' to
1.213 + disable caching.
1.214 +
1.215 +`--config-cache'
1.216 +`-C'
1.217 + Alias for `--cache-file=config.cache'.
1.218 +
1.219 +`--quiet'
1.220 +`--silent'
1.221 +`-q'
1.222 + Do not print messages saying which checks are being made. To
1.223 + suppress all normal output, redirect it to `/dev/null' (any error
1.224 + messages will still be shown).
1.225 +
1.226 +`--srcdir=DIR'
1.227 + Look for the package's source code in directory DIR. Usually
1.228 + `configure' can determine that directory automatically.
1.229 +
1.230 +`configure' also accepts some other, not widely useful, options. Run
1.231 +`configure --help' for more details.
