| Basic Installation
 | |
| ==================
 | |
| 
 | |
|    These are generic installation instructions.
 | |
| 
 | |
|    The `configure' shell script attempts to guess correct values for
 | |
| various system-dependent variables used during compilation.  It uses
 | |
| those values to create a `Makefile' in each directory of the package.
 | |
| It may also create one or more `.h' files containing system-dependent
 | |
| definitions.  Finally, it creates a shell script `config.status' that
 | |
| you can run in the future to recreate the current configuration, a file
 | |
| `config.cache' that saves the results of its tests to speed up
 | |
| reconfiguring, and a file `config.log' containing compiler output
 | |
| (useful mainly for debugging `configure').
 | |
| 
 | |
|    If you need to do unusual things to compile the package, please try
 | |
| to figure out how `configure' could check whether to do them, and mail
 | |
| diffs or instructions to the address given in the `README' so they can
 | |
| be considered for the next release.  If at some point `config.cache'
 | |
| contains results you don't want to keep, you may remove or edit it.
 | |
| 
 | |
|    The file `configure.ac' is used to create `configure' by a program
 | |
| called `autoconf'.  You only need `configure.ac' if you want to change
 | |
| it or regenerate `configure' using a newer version of `autoconf'.
 | |
| 
 | |
| The simplest way to compile this package is:
 | |
| 
 | |
|   1. `cd' to the directory containing the package's source code and type
 | |
|      `./configure' to configure the package for your system.  If you're
 | |
|      using `csh' on an old version of System V, you might need to type
 | |
|      `sh ./configure' instead to prevent `csh' from trying to execute
 | |
|      `configure' itself.
 | |
| 
 | |
|      Running `configure' takes awhile.  While running, it prints some
 | |
|      messages telling which features it is checking for.
 | |
| 
 | |
|   2. Type `make' to compile the package.
 | |
| 
 | |
|   3. Optionally, type `make check' to run any self-tests that come with
 | |
|      the package.
 | |
| 
 | |
|   4. Type `make install' to install the programs and any data files and
 | |
|      documentation.
 | |
| 
 | |
|   5. You can remove the program binaries and object files from the
 | |
|      source code directory by typing `make clean'.  To also remove the
 | |
|      files that `configure' created (so you can compile the package for
 | |
|      a different kind of computer), type `make distclean'.  There is
 | |
|      also a `make maintainer-clean' target, but that is intended mainly
 | |
|      for the package's developers.  If you use it, you may have to get
 | |
|      all sorts of other programs in order to regenerate files that came
 | |
|      with the distribution.
 | |
| 
 | |
| Compilers and Options
 | |
| =====================
 | |
| 
 | |
|    Some systems require unusual options for compilation or linking that
 | |
| the `configure' script does not know about.  You can give `configure'
 | |
| initial values for variables by setting them in the environment.  Using
 | |
| a Bourne-compatible shell, you can do that on the command line like
 | |
| this:
 | |
|      CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
 | |
| 
 | |
| Or on systems that have the `env' program, you can do it like this:
 | |
|      env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
 | |
| 
 | |
| Compiling For Multiple Architectures
 | |
| ====================================
 | |
| 
 | |
|    You can compile the package for more than one kind of computer at the
 | |
| same time, by placing the object files for each architecture in their
 | |
| own directory.  To do this, you must use a version of `make' that
 | |
| supports the `VPATH' variable, such as GNU `make'.  `cd' to the
 | |
| directory where you want the object files and executables to go and run
 | |
| the `configure' script.  `configure' automatically checks for the
 | |
| source code in the directory that `configure' is in and in `..'.
 | |
| 
 | |
|    If you have to use a `make' that does not supports the `VPATH'
 | |
| variable, you have to compile the package for one architecture at a time
 | |
| in the source code directory.  After you have installed the package for
 | |
| one architecture, use `make distclean' before reconfiguring for another
 | |
| architecture.
 | |
| 
 | |
|    On MacOS X 10.5 and later systems, you can create libraries and
 | |
| executables that work on multiple system types--known as "fat" or
 | |
| "universal" binaries--by specifying multiple '-arch' options to the
 | |
| compiler but only a single '-arch' option to the preprocessor.  Like
 | |
| this:
 | |
| 
 | |
|      ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
 | |
|                  CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
 | |
|                  CPP="gcc -E" CXXCPP="g++ -E"
 | |
| 
 | |
|    This is not guaranteed to produce working output in all cases.  You
 | |
| may have to build one architecture at a time and combine the results
 | |
| using the 'lipo' tool if you have problems.
 | |
| 
 | |
| Installation Names
 | |
| ==================
 | |
| 
 | |
|    By default, `make install' will install the package's files in
 | |
| `/usr/local/bin', `/usr/local/man', etc.  You can specify an
 | |
| installation prefix other than `/usr/local' by giving `configure' the
 | |
| option `--prefix=PATH'.
 | |
| 
 | |
|    You can specify separate installation prefixes for
 | |
| architecture-specific files and architecture-independent files.  If you
 | |
| give `configure' the option `--exec-prefix=PATH', the package will use
 | |
| PATH as the prefix for installing programs and libraries.
 | |
| Documentation and other data files will still use the regular prefix.
 | |
| 
 | |
|    In addition, if you use an unusual directory layout you can give
 | |
| options like `--bindir=PATH' to specify different values for particular
 | |
| kinds of files.  Run `configure --help' for a list of the directories
 | |
| you can set and what kinds of files go in them.
 | |
| 
 | |
|    If the package supports it, you can cause programs to be installed
 | |
| with an extra prefix or suffix on their names by giving `configure' the
 | |
| option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
 | |
| 
 | |
| Relocatable Installation
 | |
| ========================
 | |
| 
 | |
|    By default, `make install' will install a package with hardwired
 | |
| file names, and the package will not work correctly when copied or
 | |
| moved to a different location in the filesystem.
 | |
| 
 | |
|    Some packages pay attention to the `--enable-relocatable' option to
 | |
| `configure'.  This option makes the entire installed package
 | |
| relocatable.  This means, it can be moved or copied to a different
 | |
| location on the filesystem.  It is possible to make symlinks to the
 | |
| installed and moved programs, and invoke them through the symlink.  It
 | |
| is possible to do the same thing  with a hard link _only_ if the hard
 | |
| linked file is in the same directory as the real program.
 | |
| 
 | |
|    For reliability it is best to give together with --enable-relocatable
 | |
| a `--prefix' option pointing to an otherwise unused (and never used
 | |
| again) directory, for example, `--prefix=/tmp/inst$$'.  This is
 | |
| recommended because on some OSes the executables remember the location
 | |
| of shared libraries (and prefer them over LD_LIBRARY_PATH !), therefore
 | |
| such an executable will look for its shared libraries first in the
 | |
| original installation directory and only then in the current
 | |
| installation directory.
 | |
| 
 | |
|    Installation with `--enable-relocatable' will not work for setuid /
 | |
| setgid executables.  (This is because such an executable kills its
 | |
| LD_LIBRARY_PATH variable when it is launched.)
 | |
| 
 | |
|    The runtime penalty and size penalty are nearly zero on Linux 2.2 or
 | |
| newer (just one system call more when an executable is launched), and
 | |
| small on other systems (the wrapper program just sets an environment
 | |
| variable and execs the real program).
 | |
| 
 | |
| Optional Features
 | |
| =================
 | |
| 
 | |
|    Some packages pay attention to `--enable-FEATURE' options to
 | |
| `configure', where FEATURE indicates an optional part of the package.
 | |
| They may also pay attention to `--with-PACKAGE' options, where PACKAGE
 | |
| is something like `gnu-as' or `x' (for the X Window System).  The
 | |
| `README' should mention any `--enable-' and `--with-' options that the
 | |
| package recognizes.
 | |
| 
 | |
|    For packages that use the X Window System, `configure' can usually
 | |
| find the X include and library files automatically, but if it doesn't,
 | |
| you can use the `configure' options `--x-includes=DIR' and
 | |
| `--x-libraries=DIR' to specify their locations.
 | |
| 
 | |
|    For packages that use the GNU libiconv library, you can use the
 | |
| `configure' option `--with-libiconv-prefix' to specify the prefix you
 | |
| used while installing GNU libiconv.  This option is not necessary if
 | |
| that other prefix is the same as the one now specified through --prefix.
 | |
| 
 | |
|    For packages that use the GNU libintl library, you can use the
 | |
| `configure' option `--with-libintl-prefix' to specify the prefix you
 | |
| used while installing GNU gettext-runtime.  This option is not necessary if
 | |
| that other prefix is the same as the one now specified through --prefix.
 | |
| 
 | |
| Particular Systems
 | |
| ==================
 | |
| 
 | |
|    On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
 | |
| is not installed, it is recommended to use the following options in order
 | |
| to use an ANSI C compiler:
 | |
| 
 | |
|      ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
 | |
| 
 | |
| and if that doesn't work, install pre-built binaries of GCC for HP-UX.
 | |
| 
 | |
|    On AIX 3, the C include files by default don't define some necessary
 | |
| prototype declarations.  If GNU CC is not installed, it is recommended to
 | |
| use the following options:
 | |
| 
 | |
|      ./configure CC="xlc -D_ALL_SOURCE"
 | |
| 
 | |
|    On BeOS, user installed software goes in /boot/home/config, not
 | |
| /usr/local.  It is recommended to use the following options:
 | |
| 
 | |
|      ./configure --prefix=/boot/home/config
 | |
| 
 | |
| Specifying the System Type
 | |
| ==========================
 | |
| 
 | |
|    There may be some features `configure' can not figure out
 | |
| automatically, but needs to determine by the type of host the package
 | |
| will run on.  Usually `configure' can figure that out, but if it prints
 | |
| a message saying it can not guess the host type, give it the
 | |
| `--host=TYPE' option.  TYPE can either be a short name for the system
 | |
| type, such as `sun4', or a canonical name with three fields:
 | |
|      CPU-COMPANY-SYSTEM
 | |
| 
 | |
| See the file `config.sub' for the possible values of each field.  If
 | |
| `config.sub' isn't included in this package, then this package doesn't
 | |
| need to know the host type.
 | |
| 
 | |
|    If you are building compiler tools for cross-compiling, you can also
 | |
| use the `--target=TYPE' option to select the type of system they will
 | |
| produce code for and the `--build=TYPE' option to select the type of
 | |
| system on which you are compiling the package.
 | |
| 
 | |
| Sharing Defaults
 | |
| ================
 | |
| 
 | |
|    If you want to set default values for `configure' scripts to share,
 | |
| you can create a site shell script called `config.site' that gives
 | |
| default values for variables like `CC', `cache_file', and `prefix'.
 | |
| `configure' looks for `PREFIX/share/config.site' if it exists, then
 | |
| `PREFIX/etc/config.site' if it exists.  Or, you can set the
 | |
| `CONFIG_SITE' environment variable to the location of the site script.
 | |
| A warning: not all `configure' scripts look for a site script.
 | |
| 
 | |
| Operation Controls
 | |
| ==================
 | |
| 
 | |
|    `configure' recognizes the following options to control how it
 | |
| operates.
 | |
| 
 | |
| `--cache-file=FILE'
 | |
|      Use and save the results of the tests in FILE instead of
 | |
|      `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
 | |
|      debugging `configure'.
 | |
| 
 | |
| `--help'
 | |
|      Print a summary of the options to `configure', and exit.
 | |
| 
 | |
| `--quiet'
 | |
| `--silent'
 | |
| `-q'
 | |
|      Do not print messages saying which checks are being made.  To
 | |
|      suppress all normal output, redirect it to `/dev/null' (any error
 | |
|      messages will still be shown).
 | |
| 
 | |
| `--srcdir=DIR'
 | |
|      Look for the package's source code in directory DIR.  Usually
 | |
|      `configure' can determine that directory automatically.
 | |
| 
 | |
| `--version'
 | |
|      Print the version of Autoconf used to generate the `configure'
 | |
|      script, and exit.
 | |
| 
 | |
| `configure' also accepts some other, not widely useful, options.
 | |
|
