2.1 Installing the Example Package
To install the Example package, unpack the archive file, which should
have a name of form example-XXX.zoo for some version number XXX, by
typing
unzoo -x example-XXX
in the pkg directory of your version of GAP 4, or in a directory
named pkg (e.g. in your home directory; see Section Installing a GAP Package in your home directory). (The only essential difference with
installing Example in a pkg directory different to the GAP 4 home
directory is that one must start GAP with the -l switch, e.g. if
your private pkg directory is a subdirectory of mygap in your home
directory you might type:
gap -l ";myhomedir/mygap"
where myhomedir is the path to your home directory, which may be replaced by a tilde in GAP 4.3 or later. The empty path before the semicolon is filled in by the default path of the GAP 4 home directory.)
After unpacking the archive, go to the newly created example directory
and call ./configure path where path is the path to the GAP home
directory. So for example if you install the package in the main pkg
directory call
./configure ../..
This will fetch the architecture type for which GAP has been compiled
last and create a Makefile. Now simply call
make
to compile the binary and to install it in the appropriate place.
2.2 Loading the Example Package
To use the Example Package you have to request it explicitly. This is done by calling
gap> RequirePackage("example");
The Example package
Version 1.2
by Werner Nickel
For help, type: ?Example package
true
The RequirePackage command is described in Section RequirePackage
in the GAP Reference Manual.
If GAP cannot find a working binary, the call to RequirePackage will
still succeed but a warning is issued informing that the HelloWorld()
function will be unavailable.
The banner is suppressed if the global GAP variable QUIET is true
or BANNER is false (these conditions occur if GAP is invoked with
the -q or -b command line switches, respectively). If you want to
load the Example package by default, you can put the RequirePackage
command into your .gaprc file (see Section The .gaprc file in the
GAP Reference Manual).
