Basic Installation
==================
These are generic installation instructions.
These are installation instructions for Readline-4.3.
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').
The simplest way to compile readline is:
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.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.

`configure' itself.

libraries will be built also. See below for instructions on compiling
the other parts of the distribution. Typing `make everything' will
cause the static and shared libraries (if supported) and the example
programs to be built.
3. Optionally, type `make check' to run any self-tests that come with
the package.

libraries, the readline include files, the documentation, and, if
supported, the shared readline and history libraries.

Some systems require unusual options for compilation or linking that

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:

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

If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile readline for one architecture at a

readline for one architecture, use `make distclean' before
reconfiguring for another architecture.
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'.
By default, `make install' will install the readline libraries in
`/usr/local/lib', the include files in
`/usr/local/include/readline', the man pages in `/usr/local/man',
and the info files in `/usr/local/info'. You can specify an
installation prefix other than `/usr/local' by giving `configure'
the option `--prefix=PATH' or by supplying a value for the
DESTDIR variable when running `make install'.
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.
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'.
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.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.
If you give `configure' the option `--exec-prefix=PATH', the
readline Makefiles will use PATH as the prefix for installing the
libraries. Documentation and other data files will still use the
regular prefix.
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
There may be some features `configure' can not figure out
automatically, but need to determine by the type of host readline
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 (e.g., i386-unknown-freebsd4.2).
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.
See the file `config.sub' for the possible values of each field.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
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'.

`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.

`configure' also accepts some other, not widely useful, options.
Optional Features
=================
The readline `configure' recognizes a single `--with-PACKAGE' option:
`--with-curses'
This tells readline that it can find the termcap library functions
(tgetent, et al.) in the curses library, rather than a separate
termcap library. Readline uses the termcap functions, but does not
link with the termcap or curses library itself, allowing applications
which link with readline the to choose an appropriate library.
This option tells readline to link the example programs with the
curses library rather than libtermcap.
`configure' also recognizes two `--enable-FEATURE' options:
`--enable-shared'
Build the shared libraries by default on supported platforms. The
default is `yes'.
`--enable-static'
Build the static libraries by default. The default is `yes'.
Shared Libraries
================
There is support for building shared versions of the readline and
history libraries. The configure script creates a Makefile in
the `shlib' subdirectory, and typing `make shared' will cause
shared versions of the readline and history libraries to be built
on supported platforms.
If `configure' is given the `--enable-shared' option, it will attempt
to build the shared libraries by default on supported platforms.
Configure calls the script support/shobj-conf to test whether or
not shared library creation is supported and to generate the values
of variables that are substituted into shlib/Makefile. If you
try to build shared libraries on an unsupported platform, `make'
will display a message asking you to update support/shobj-conf for
your platform.
If you need to update support/shobj-conf, you will need to create
a `stanza' for your operating system and compiler. The script uses
the value of host_os and ${CC} as determined by configure. For
instance, FreeBSD 4.2 with any version of gcc is identified as
`freebsd4.2-gcc*'.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
position-independent code. If you are using gcc, this
should probably be set to `-fpic'.
SHOBJ_LD The link editor to be used to create the shared library from
the object files created by $SHOBJ_CC. If you are using
gcc, a value of `gcc' will probably work.
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
If you are using gcc, `-shared' may be all that is necessary.
These should be the flags needed for generic shared object
creation.
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
creation. Many systems use the -R option to the link
editor to embed a path within the library for run-time
library searches. A reasonable value for such systems would
be `-R$(libdir)'.
SHLIB_LIBS Any additional libraries that shared libraries should be
linked against when they are created.
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
generating the filename of the shared library. Many systems
use `so'; HP-UX uses `sl'.
SHLIB_LIBVERSION The string to append to the filename to indicate the version
of the shared library. It should begin with $(SHLIB_LIBSUFF),
and possibly include version information that allows the
run-time loader to load the version of the shared library
appropriate for a particular program. Systems using shared
libraries similar to SunOS 4.x use major and minor library
version numbers; for those systems a value of
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
Systems based on System V Release 4 don't use minor version
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
Other Unix versions use different schemes.
SHLIB_STATUS Set this to `supported' when you have defined the other
necessary variables. Make uses this to determine whether
or not shared library creation should be attempted. If
shared libraries are not supported, this will be set to
`unsupported'.
You should look at the existing stanzas in support/shobj-conf for ideas.
Once you have updated support/shobj-conf, re-run configure and type
`make shared' or `make'. The shared libraries will be created in the
shlib subdirectory.
If shared libraries are created, `make install' will install them.
You may install only the shared libraries by running `make
install-shared' from the top-level build directory. Running `make
install' in the shlib subdirectory will also work. If you don't want
to install any created shared libraries, run `make install-static'.
