! 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.
