This is version 3.0 of Guile, Project GNU's extension language library.
Guile is an implementation of the Scheme programming language, packaged
as a library that can be linked into applications to give them their own
extension language. Guile supports other languages as well, giving
users of Guile-based applications a choice of languages.

Please send bug reports to bug-guile@gnu.org.

See the LICENSE file for the specific terms that apply to Guile. Note
that for any copyright year range specified as YYYY-ZZZZ in this
package, the range specifies every single year in that closed interval.

Additional INSTALL instructions ===========================================

Generic instructions for configuring and compiling Guile can be found
in the INSTALL file. Guile specific information and configure options
can be found below, including instructions for installing SLIB.

Guile depends on the following external libraries.
- libgmp
- libiconv
- libintl
- libltdl
- libunistring
- libgc
- libffi
It will also use the libreadline library if it is available.

There is a corresponding `--with-XXX-prefix' option for each of these
libraries (except for libgc and libffi which use `pkg-config', see
below) that you can use when invoking ./configure, if you have these
libraries installed in a location other than the standard places (/usr
and /usr/local).

These options are provided by the Gnulib `havelib' module, and details
of how they work are documented in `Searching for Libraries' in the
Gnulib manual (http://www.gnu.org/software/gnulib/manual). The extent
to which they work on a given OS depends on whether that OS supports
encoding full library path names in executables (aka `rpath'). Also
note that using these options, and hence hardcoding full library path
names (where that is supported), makes it impossible to later move the
built executables and libraries to an installation location other than
the one that was specified at build time.

Another possible approach is to set CPPFLAGS and LDFLAGS on the
configure command-line, so that they include -I options for all the
non-standard places where you have installed header files and -L
options for all the non-standard places where you have installed
libraries. This will allow configure and make to find those headers
and libraries during the build. E.g.:

../configure [...] CPPFLAGS='-I/my/include' LDFLAGS='-L/my/lib'

The locations found will not be hardcoded into the build executables and
libraries, so with this approach you will probably also need to set
LD_LIBRARY_PATH correspondingly, to allow Guile to find the necessary
libraries again at runtime.

Required External Packages ================================================

Guile requires the following external packages:

- GNU MP, at least version 4.2

GNU MP is used for bignum arithmetic. It is available from
http://gmplib.org/ .

- libltdl from GNU Libtool, at least version 1.5.6

libltdl is used for loading extensions at run-time. It is
available from http://www.gnu.org/software/libtool/ .

- GNU libunistring, at least version 0.9.3

libunistring is used for Unicode string operations, such as the
`utf*->string' procedures. It is available from
http://www.gnu.org/software/libunistring/ .

- libgc, at least version 7.2

libgc (aka. the Boehm-Demers-Weiser garbage collector) is the
conservative garbage collector used by Guile. It is available
from http://www.hboehm.info/gc/ .

- libffi

libffi provides a "foreign function interface", used by the
`(system foreign)' module. It is available from
http://sourceware.org/libffi/ .

- pkg-config

Guile's ./configure script uses pkg-config to discover the correct
compile and link options for libgc and libffi. For this to work,
the `PKG_CONFIG_PATH' environment variable must be set to point to
the places where libgc's and libffi's `.pc' files can be found:


Alternatively, when pkg-config is not installed, you can work around
this by setting some variables as part of the configure




Note that because you're bypassing all pkg-config checks, you will
also have to specify libffi flags as well:



When building from a Git checkout, these additional packages are needed:

- GNU Autoconf
- GNU Automake
- GNU Libtool
- Flex
- GNU Gettext
- GNU Texinfo

Special Instructions For Some Systems =====================================

We would like Guile to build on all systems using the simple
instructions above, but it seems that a few systems still need special
treatment. If you can send us fixes for these problems, we'd be

FreeBSD 11.0:
For a build supporting threads, please `pkg install' the following
- pkgconf : provides pkg-config
- gmake : /usr/bin/make does not work
- boehm-gc-threaded : needed for threaded support

Configure as:

./configure --with-bdw-gc=bdw-gc-threaded

Alternately if you want a Guile without threads, then install boehm-gc
and configure as:

./configure --without-threads

Guile specific flags Accepted by Configure =================================

If you run the configure script with no arguments, it should examine
your system and set things up appropriately. However, there are a few
switches specific to Guile you may find useful in some circumstances.

--without-threads --- Build without thread support

Build a Guile executable and library that supports multi-threading.

The default is to enable threading support when your operating
system offsers 'POSIX threads'. When you do not want threading, use


Guile may contain features that are `deprecated'. When a feature is
deprecated, it means that it is still there, but that there is a
better way of achieving the same thing, and we'd rather have you use
this better way. This allows us to eventually remove the old
implementation and helps to keep Guile reasonably clean of historic

See the file NEWS for a list of features that are currently
deprecated. Each entry will also tell you what you should replace
your code with.

To give you some help with this process, and to encourage (OK,
nudge) people to switch to the newer methods, Guile can emit
warnings or errors when you use a deprecated feature. There is
quite a range of possibilities, from being completely silent to
giving errors at link time. What exactly happens is determined both
by the value of the `--enable-deprecated' configuration option when
Guile was built, and by the GUILE_WARN_DEPRECATED environment

It works like this:

When Guile has been configured with `--enable-deprecated=no' (or,
equivalently, with `--disable-deprecated') then all deprecated
features are omitted from Guile. You will get "undefined
reference", "variable unbound" or similar errors when you try to
use them.

When `--enable-deprecated=LEVEL' has been specified (for LEVEL not
"no"), LEVEL will be used as the default value of the environment
variable GUILE_WARN_DEPRECATED. A value of "yes" is changed to
"summary" and "shutup" is changed to "no", however.

When GUILE_WARN_DEPRECATED has the value "no", nothing special
will happen when a deprecated feature is used.

When GUILE_WARN_DEPRECATED has the value "summary", and a
deprecated feature has been used, Guile will print this message at

Some deprecated features have been used. Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information. Set it to "no" to suppress
this message.

When GUILE_WARN_DEPRECATED has the value "detailed", a detailed
warning is emitted immediatly for the first use of a deprecated

The default is `--enable-deprecated=yes'.

In addition to setting GUILE_WARN_DEPRECATED in the environment, you
can also use (debug-enable 'warn-deprecated) and (debug-disable
'warn-deprecated) to enable and disable the detailed messaged at run

Additionally, if your toolchain is new enough, you will receive
warnings at link time if you have a Guile extension that uses
deprecated functions provided by Guile.

--disable-shared --- Do not build shared libraries.
--disable-static --- Do not build static libraries.

Normally, both static and shared libraries will be built if your
system supports them.

--enable-debug-freelist --- Enable freelist debugging.

This enables a debugging version of scm_cell and scm_double_cell,
and also registers an extra primitive, the setter

Configure with the --enable-debug-freelist option to enable the
gc-set-debug-check-freelist! primitive, and then use:

(gc-set-debug-check-freelist! #t) # turn on checking of the freelist
(gc-set-debug-check-freelist! #f) # turn off checking

Checking of the freelist forces a traversal of the freelist and a
garbage collection before each allocation of a cell. This can slow
down the interpreter dramatically, so the setter should be used to
turn on this extra processing only when necessary.

--enable-debug-malloc --- Enable malloc debugging.

Include code for debugging of calls to scm_malloc, scm_realloc, etc.

It records the number of allocated objects of each kind. This is
useful when searching for memory leaks.

A Guile compiled with this option provides the primitive
`malloc-stats' which returns an alist with pairs of kind and the
number of objects of that kind.

--enable-guile-debug --- Include internal debugging functions
--disable-posix --- omit posix interfaces
--disable-networking --- omit networking interfaces
--disable-regex --- omit regular expression interfaces

Cross building Guile =====================================================

As of Guile 3.0.x, the build process produces a library, libguile-3.0,
along with Guile "object files" containing bytecode to be interpreted by
Guile's virtual machine. The bytecode format depends on the endianness
and word size of the host CPU.

Thus, when cross building Guile, you first need to configure, build and
install it for your build host.

Then, you may configure Guile for cross building:

./configure --host=i686-pc-cygwin --disable-shared

A C compiler for the build system is required. If that doesn't suit it
can be specified with the CC_FOR_BUILD variable in the usual way, for

./configure --host=m68k-unknown-linux-gnu CC_FOR_BUILD=/my/local/gcc

Guile for the build system can be specified similarly with the
GUILE_FOR_BUILD variable, which defaults to whatever `guile' executable
is found in $PATH. It must have the exact same version has the Guile
that you intend to cross-build.

Using Guile Without Installing It =========================================

The "meta/" subdirectory of the Guile sources contains a script called
"guile" that can be used to run the Guile that has just been built. Note
that this is not the same "guile" as the one that is installed; this
"guile" is a wrapper script that sets up the environment appropriately,
then invokes the Guile binary.

You may also build external packages against an uninstalled Guile build
tree. The "uninstalled-env" script in the "meta/" subdirectory will set
up an environment with a path including "meta/", a modified dynamic
linker path, a modified PKG_CONFIG_PATH, etc.

For example, you can enter this environment via invoking

meta/uninstalled-env bash

Within that shell, other packages should be able to build against
uninstalled Guile.

Installing SLIB ===========================================================

In order to use SLIB from Guile you basically only need to put the
`slib' directory _in_ one of the directories on Guile's load path.

The standard installation is:

1. Obtain slib from http://www-swiss.ai.mit.edu/~jaffer/SLIB.html

2. Put it in Guile's data directory, that is the directory printed when
you type

guile-config info pkgdatadir

at the shell prompt. This is normally `/usr/local/share/guile', so the
directory will normally have full path `/usr/local/share/guile/slib'.

3. Start guile as a user with write access to the data directory and type

(use-modules (ice-9 slib))

at the Guile prompt. This will generate the slibcat catalog next to
the slib directory.

SLIB's `require' is provided by the Guile module (ice-9 slib).


(use-modules (ice-9 slib))
(require 'primes)
(prime? 7)

Guile Documentation ==================================================

The Guile Reference Manual (guile.info) is the primary documentation for
Guile. A copy of the R5RS Scheme specification is included too

Info format versions of this documentation are installed as part of
the normal build process. The texinfo sources are under the doc
directory, and other formats like Postscript, PDF, DVI or HTML can be
generated from them with Tex and Texinfo tools.

The doc directory also includes an example-smob subdirectory which has
the example code from the "Defining New Types (Smobs)" chapter of the
reference manual.

The Guile WWW page is at


It contains a link to the Guile FAQ.
