    1: Basic Installation
    2: ==================
    4:    These are generic installation instructions.
    6:    The `configure' shell script attempts to guess correct values for
    7: various system-dependent variables used during compilation.  It uses
    8: those values to create a `Makefile' in each directory of the package.
    9: It may also create one or more `.h' files containing system-dependent
   10: definitions.  Finally, it creates a shell script `config.status' that
   11: you can run in the future to recreate the current configuration, a file
   12: `config.cache' that saves the results of its tests to speed up
   13: reconfiguring, and a file `config.log' containing compiler output
   14: (useful mainly for debugging `configure').
   16:    If you need to do unusual things to compile the package, please try
   17: to figure out how `configure' could check whether to do them, and mail
   18: diffs or instructions to the address given in the `README' so they can
   19: be considered for the next release.  If at some point `config.cache'
   20: contains results you don't want to keep, you may remove or edit it.
   22:    The file `' is used to create `configure' by a program
   23: called `autoconf'.  You only need `' if you want to change
   24: it or regenerate `configure' using a newer version of `autoconf'.
   26: The simplest way to compile this package is:
   28:   1. `cd' to the directory containing the package's source code and type
   29:      `./configure' to configure the package for your system.  If you're
   30:      using `csh' on an old version of System V, you might need to type
   31:      `sh ./configure' instead to prevent `csh' from trying to execute
   32:      `configure' itself.
   34:      Running `configure' takes awhile.  While running, it prints some
   35:      messages telling which features it is checking for.
   37:   2. Type `make' to compile the package.
   39:   3. Optionally, type `make check' to run any self-tests that come with
   40:      the package.
   42:   4. Type `make install' to install the programs and any data files and
   43:      documentation.
   45:   5. You can remove the program binaries and object files from the
   46:      source code directory by typing `make clean'.  To also remove the
   47:      files that `configure' created (so you can compile the package for
   48:      a different kind of computer), type `make distclean'.  There is
   49:      also a `make maintainer-clean' target, but that is intended mainly
   50:      for the package's developers.  If you use it, you may have to get
   51:      all sorts of other programs in order to regenerate files that came
   52:      with the distribution.
   54: Compilers and Options
   55: =====================
   57:    Some systems require unusual options for compilation or linking that
   58: the `configure' script does not know about.  You can give `configure'
   59: initial values for variables by setting them in the environment.  Using
   60: a Bourne-compatible shell, you can do that on the command line like
   61: this:
   62:      CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
   64: Or on systems that have the `env' program, you can do it like this:
   65:      env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
   67: Compiling For Multiple Architectures
   68: ====================================
   70:    You can compile the package for more than one kind of computer at the
   71: same time, by placing the object files for each architecture in their
   72: own directory.  To do this, you must use a version of `make' that
   73: supports the `VPATH' variable, such as GNU `make'.  `cd' to the
   74: directory where you want the object files and executables to go and run
   75: the `configure' script.  `configure' automatically checks for the
   76: source code in the directory that `configure' is in and in `..'.
   78:    If you have to use a `make' that does not supports the `VPATH'
   79: variable, you have to compile the package for one architecture at a time
   80: in the source code directory.  After you have installed the package for
   81: one architecture, use `make distclean' before reconfiguring for another
   82: architecture.
   84: Installation Names
   85: ==================
   87:    By default, `make install' will install the package's files in
   88: `/usr/local/bin', `/usr/local/man', etc.  You can specify an
   89: installation prefix other than `/usr/local' by giving `configure' the
   90: option `--prefix=PATH'.
   92:    You can specify separate installation prefixes for
   93: architecture-specific files and architecture-independent files.  If you
   94: give `configure' the option `--exec-prefix=PATH', the package will use
   95: PATH as the prefix for installing programs and libraries.
   96: Documentation and other data files will still use the regular prefix.
   98:    In addition, if you use an unusual directory layout you can give
   99: options like `--bindir=PATH' to specify different values for particular
  100: kinds of files.  Run `configure --help' for a list of the directories
  101: you can set and what kinds of files go in them.
  103:    If the package supports it, you can cause programs to be installed
  104: with an extra prefix or suffix on their names by giving `configure' the
  105: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
  107: Optional Features
  108: =================
  110:    Some packages pay attention to `--enable-FEATURE' options to
  111: `configure', where FEATURE indicates an optional part of the package.
  112: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
  113: is something like `gnu-as' or `x' (for the X Window System).  The
  114: `README' should mention any `--enable-' and `--with-' options that the
  115: package recognizes.
  117:    For packages that use the X Window System, `configure' can usually
  118: find the X include and library files automatically, but if it doesn't,
  119: you can use the `configure' options `--x-includes=DIR' and
  120: `--x-libraries=DIR' to specify their locations.
  122: Specifying the System Type
  123: ==========================
  125:    There may be some features `configure' can not figure out
  126: automatically, but needs to determine by the type of host the package
  127: will run on.  Usually `configure' can figure that out, but if it prints
  128: a message saying it can not guess the host type, give it the
  129: `--host=TYPE' option.  TYPE can either be a short name for the system
  130: type, such as `sun4', or a canonical name with three fields:
  133: See the file `config.sub' for the possible values of each field.  If
  134: `config.sub' isn't included in this package, then this package doesn't
  135: need to know the host type.
  137:    If you are building compiler tools for cross-compiling, you can also
  138: use the `--target=TYPE' option to select the type of system they will
  139: produce code for and the `--build=TYPE' option to select the type of
  140: system on which you are compiling the package.
  142: Sharing Defaults
  143: ================
  145:    If you want to set default values for `configure' scripts to share,
  146: you can create a site shell script called `' that gives
  147: default values for variables like `CC', `cache_file', and `prefix'.
  148: `configure' looks for `PREFIX/share/' if it exists, then
  149: `PREFIX/etc/' if it exists.  Or, you can set the
  150: `CONFIG_SITE' environment variable to the location of the site script.
  151: A warning: not all `configure' scripts look for a site script.
  153: Operation Controls
  154: ==================
  156:    `configure' recognizes the following options to control how it
  157: operates.
  159: `--cache-file=FILE'
  160:      Use and save the results of the tests in FILE instead of
  161:      `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
  162:      debugging `configure'.
  164: `--help'
  165:      Print a summary of the options to `configure', and exit.
  167: `--quiet'
  168: `--silent'
  169: `-q'
  170:      Do not print messages saying which checks are being made.  To
  171:      suppress all normal output, redirect it to `/dev/null' (any error
  172:      messages will still be shown).
  174: `--srcdir=DIR'
  175:      Look for the package's source code in directory DIR.  Usually
  176:      `configure' can determine that directory automatically.
  178: `--version'
  179:      Print the version of Autoconf used to generate the `configure'
  180:      script, and exit.
  182: `configure' also accepts some other, not widely useful, options.
