If after reading the information on the web pages you still face
unsurmountable problems, please send an email to
firstname.lastname@example.org, describing your problems. (Include the
operating system you are using and the error messages or indications of
installation failure that you get.)
Once installation is complete, please send a short note to
email@example.com to inform us of the installation.
For a complete installation fetch the files

(with the extensions of your choice, see above).
Note, that certain packages will not or not fully work on Windows or
Macintosh systems, see the package infos on our Web pages for details.
and (optional additional tables of marks, need about 80 MB on disc)
(In contrast to older versions, the installation archives provided will
always contain the most recent bugfix -- if you install GAP afresh you do not
need to fetch any bugfix.)
INSTALLATION UNDER UNIX AND OS X
While the `gap4r4p12' archive must be unpacked *in* the directory
in which you want GAP's root directory to sit (say, '/usr/local/lib/', a
subdirectory 'gap4r4' is created), the
`packages...' archive must be extracted into the
`gap4r4/pkg' subdirectory created by the first extraction.
To compile GAP on UNIX/Linux/OS X systems you can often just say
inside GAP's root directory and copy the start script bin/gap.sh under
some name (probably 'gap') into a generally used bin directory (e.g.,
More information on compilation and optimization options can be found on the
Note that some packages need further installation/configuration. See the
README.* files in the 'pkg' subdirectory.
INSTALLATION UNDER WINDOWS
Decompress 'gap4r4p12-win.zip' on the top-level directory of drive C:\.
This creates a directory C:\GAP4R4, the 'GAP root directory'. Then
extract 'packages...-win.zip' into C:\GAP4R4\pkg\.
Click on C:\gap4r4p12\bin\gapw95.exe to start GAP.
(It is possible that using the rxvt shell via
C:\GAP4R4\bin\gaprxvt.bat will give a nicer user interface.
However, please note that we cannot provide support for this shell.)
To make GAP accessible from the start menu, create a link 'GAP
C:\GAP4R4\bin\gapw95.exe in a submenu of the start menu of your choice.
(If you want to install GAP in another directory, you will have to create a
suitable batch file -- see the `Installation' chapter of the reference
manual on the web pages.)
For getting access to the documentation via the start menu, you can also
create such links to the manual books, e.g. to C:\GAP4R4\doc\ref\manual.pdf
for the PDF- resp. HTML version of the reference manual. Of course,
this requires viewers for the respective types of files to be installed.
INSTALLATION ON MAC OS
Decompress 'unzoo4r4-...sit' (using, e. g. , Stuffit
Expander). You should now have an application 'unzoo'.
Move this application and gap4r4p12.zoo into the folder in
which you want to install GAP and decompress it by dragging it onto the
'unzoo' application icon.
. This should have created a folder 'gap4r4p12' with a
'GAP 4 ...' application in this directory.
To install the GAP packages, move 'packages....zoo' into the
folder 'pkg' inside 'gap4r4' and decompress them there.
