2.1 Installing the ACE Package
To install, unpack the archive file, which should have a name of form
ace-XXX.zoo for some package version number XXX, as a
sub-directory in the pkg hierarchy of your version of GAP 4. This
might be the pkg directory of the GAP 4 home directory; it is
however also possible to keep an additional pkg directory in your
private directories, see Section Installing a GAP Package in your home directory. (The only essential difference with installing ACE
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. 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 ace 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.
Note that the current version of the configuration process only sets
up directory paths. If you need a different compiler or different
compiler options, you need to edit src/Makefile.in yourself, prior
to calling make.
If you use this installation of GAP on different hardware platforms
you will have to compile the binary for each platform separately. This
is done by calling configure, editing src/Makefile.in possibly,
and calling make for the package anew immediately after compiling
GAP itself for the respective architecture. If your version of
GAP is already compiled (and has last been compiled on the same
architecture) you do not need to compile GAP again, it is
sufficient to call the configure script in the GAP home
directory.
The manual you are currently reading describes how to use the ACE
Package; it can be found in the doc subdirectory of the package. If
your manual does not have a table of contents or index, or has these
but with invalid page numbers please re-generate the manual by
executing
./make_doc
in the doc subdirectory.
The subdirectory standalone-doc contains the file ace3001.ps which
holds a version of the user manual for the ACE standalone; it forms
part of Ram99). You should consult it if you are going to
switch to the ACE standalone, e.g. in order to directly use
interactive facilities.
The src subdirectory contains a copy of the original source of
ACE. (The only modification is that a file Makefile.in was
obtained from the different make.xyz and will be used to create a
Makefile.) You can replace the source by a newer version before
compiling.
If you encounter problems in installation please read the README.
To use the ACE Package you have to request it explicitly. This is done by calling
gap> RequirePackage( "ace" ); #I The ACE (Advanced Coset Enumerator) Package #I C code by George Havas <havas@itee.uq.edu.au> and #I Colin Ramsay <cram@itee.uq.edu.au> #I ACE binary version: 3.001 #I GAP code by Greg Gamble <gregg@itee.uq.edu.au> and #I Alexander Hulpke <hulpke@math.colostate.edu> #I ACE package version: 3.003 #I #I For help, type: ?ACE 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 fail.
If you know you have a working ACE binary, as well as a correctly
installed ACE Package, it is possible to suppress the Info
messages by temporarily setting the InfoLevel of InfoWarning to 0,
and a duplicated semicolon will suppress the true result:
gap> SetInfoLevel(InfoWarning, 0); RequirePackage( "ace" );; gap> SetInfoLevel(InfoWarning, 1);
The banner is also 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 ACE package by default, you can put the
RequirePackage command into your .gaprc file (see Section The .gaprc file in the GAP Reference Manual).
