   1 Basic Installation
   2 ==================
   3
   4    These are generic installation instructions.
   5
   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').
  15
  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.
  21
  22    The file `configure.in' is used to create `configure' by a program
  23 called `autoconf'.  You only need `configure.in' if you want to change
  24 it or regenerate `configure' using a newer version of `autoconf'.
  25
  26 The simplest way to compile this package is:
  27
  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.
  33
  34      Running `configure' takes awhile.  While running, it prints some
  35      messages telling which features it is checking for.
  36
  37   2. Type `make' to compile the package.
  38
  39   3. Optionally, type `make check' to run any self-tests that come with
  40      the package.
  41
  42   4. Type `make install' to install the programs and any data files and
  43      documentation.
  44
  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.
  53
  54 Compilers and Options
  55 =====================
  56
  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
  63
  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
  66
  67 Compiling For Multiple Architectures
  68 ====================================
  69
  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 `..'.
  77
  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.
  83
  84 Installation Names
  85 ==================
  86
  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'.
  91
  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.
  97
  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.
 102
 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'.
 106
 107 Optional Features
 108 =================
 109
 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.
 116
 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.
 121
 122 Specifying the System Type
 123 ==========================
 124
 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:
 131      CPU-COMPANY-SYSTEM
 132
 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.
 136
 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.
 141
 142 Sharing Defaults
 143 ================
 144
 145    If you want to set default values for `configure' scripts to share,
 146 you can create a site shell script called `config.site' that gives
 147 default values for variables like `CC', `cache_file', and `prefix'.
 148 `configure' looks for `PREFIX/share/config.site' if it exists, then
 149 `PREFIX/etc/config.site' 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.
 152
 153 Operation Controls
 154 ==================
 155
 156    `configure' recognizes the following options to control how it
 157 operates.
 158
 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'.
 163
 164 `--help'
 165      Print a summary of the options to `configure', and exit.
 166
 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).
 173
 174 `--srcdir=DIR'
 175      Look for the package's source code in directory DIR.  Usually
 176      `configure' can determine that directory automatically.
 177
 178 `--version'
 179      Print the version of Autoconf used to generate the `configure'
 180      script, and exit.
 181
 182 `configure' also accepts some other, not widely useful, options.
