SLIB

Before the the SLIB facilities can be used, the following Scheme expression must be executed:

(use-modules (ice-9 slib))

require can then be used as described in section `SLIB' in The SLIB Manual.

For example:

guile> (use-modules (ice-9 slib))
guile> (require 'primes)
guile> (probably-prime? 13)

SLIB installation

The following seems to work (e.g., with slib versions 2c7 and 2d2):

Unpack slib somewhere, e.g., /usr/local/share/slib.

Create a symlink in the Guile site directory to slib, e.g.,:

ln -s /usr/local/share/slib /usr/local/share/guile/site/slib

Use Guile to create the catalog file, e.g.,:
```
# guile
guile> (use-modules (ice-9 slib))
guile> (load "/usr/local/share/slib/mklibcat.scm")
guile> (quit)
```
The catalog data should now be in /usr/local/share/guile/site/slibcat. If instead you get an error such as:
```
Unbound variable: scheme-implementation-type
```
then a solution is to get a newer version of Guile, or to modify ice-9/slib.scm to use define-public for the offending variables.

Install the documentation:

cd /usr/local/share/slib
rm /usr/local/info/slib.info*
cp slib.info /usr/local/info
install-info slib.info /usr/local/info/dir

JACAL

Jacal is a symbolic math package written in Scheme by Aubrey Jaffer. It is usually installed as an extra package in SLIB (see section Packages not shipped with Guile).

You can use Guile's interface to SLIB to invoke Jacal:

(use-modules (ice-9 slib))
(slib:load "math")
(math)

For complete documentation on Jacal, please read the Jacal manual. If it has been installed on line, you can look at section `Jacal' in The SLIB Manual. Otherwise you can find it on the web at http://www-swiss.ai.mit.edu/~jaffer/JACAL.html
