==================
These are installation instructions for Readline-8.1.
The simplest way to compile readline is:
1. `cd' to the directory containing the readline source code and type
`./configure' to configure readline 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 some time. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile readline and build the static readline
and history libraries. If supported, the shared readline and history
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. Type `make install' to install the static readline and history
libraries, the readline include files, the documentation, and, if
supported, the shared readline and history libraries.
4. You can remove the created libraries and object files from the
build directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile readline for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the readline developers, and should be used with care.
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 the build directory,
and Makefiles in the `doc', `shlib', and `examples'
subdirectories. It also creates a `config.h' file 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 readline, please try
to figure out how `configure' could check whether to do them, and
mail diffs or instructions to 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'. The readline `configure.in' requires autoconf
version 2.50 or newer.
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 readline 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 readline for one architecture at a
time in the source code directory. After you have installed
readline for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
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
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 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.
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: the readline `configure' looks for a site script, but not
all `configure' scripts do.
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.
`--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.
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'.
`--enable-bracketed-paste-default'
Enable bracketed paste by default, so the initial value of the
`enable-bracketed-paste' Readline variable is `on'. 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_LIBPREF The prefix to use when generating the filename of the shared
library. The default is `lib'; Cygwin uses `cyg'.
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_DLLVERSION The version number for shared libraries that determines API
compatibility between readline versions and the underlying
system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
can be overridden at configuration time by defining DLLVERSION
in the environment.
SHLIB_DOT The character used to separate the name of the shared library
from the suffix and version information. The default is `.';
systems like Cygwin which don't separate version information
from the library name should set this to the empty string.
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'.

\`configure' configures readline 8.1 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/readline]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-multibyte enable multibyte characters if OS supports them
--enable-shared build shared libraries [[default=YES]]
--enable-static build static libraries [[default=YES]]
--disable-install-examples
don't install examples [[default=install]]
--disable-bracketed-paste-default
disable bracketed paste by default
[[default=enable]]
--disable-largefile omit support for large files
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-curses use the curses library instead of the termcap
library
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

doc/Makefile.in
- add a VPATH assignment so the documentation is not remade if it's
already up-to-date in the distribution
configure.in

@LOCAL_LDFLAGS@
7/9
---
config.h.in

they are not found in the current (build) directory -- only an
issue if the libraries are built in a different directory than
the source directory
5/1
---

8/3
---
shlib/Makefile.in
- made the suffix rule that creates xx.so from xx.c write the
compiler output to `a.o', which is then mv'd to xx.so, because
some compilers (Sun WSpro 4.2, for example) don't allow any
suffixes other than `.o' for `cc -c' (not even `a.out')

generated postscript files. Set to 300 because I don't have
any 600-dpi printers

install-headers and uninstall-headers
- install and uninstall depend on install-headers and uninstall-headers
respectively
- changed install-shared and uninstall-shared targets to depend on
install-headers and uninstall-headers, respectively, so users may
choose to install only the shared libraries. I'm not sure about
the uninstall one yet -- maybe it should check whether or not
the static libraries are installed and not remove the header files
if they are
9/3
---

the minor version number
11/13
-----
examples/rlfe.c
- rlfe can perform filename completion for relative pathnames in the
inferior process's context if the OS supports /proc/PID/cwd (linux
does it OK, Solaris is slightly warped, none of the BSDs have it)

Makefile.in
- install-examples: should not depend on `shared', since the examples
themselves are not built using shared libraries. Report from
support/shobj-conf
- [from bash] darwin: changed the install_name embedded into the
shared library to contain only the major version number, not the
minor one. The idea is that the minor versions should all be API/ABI
compatible, and it is better to link automatically with the latest
one. Idea from Max Horn
