An overview of system requirements is provided in System requirements on AIX. The sections that follow discuss any relevant details.
LispWorks 7.1 for AIX requires that the X11 release 6 (or higher) is installed.
LispWorks 7.1 also requires that either GTK+ or Open Motif with Imlib2 are installed.
The remainder of this section contains the details for each of these distinct GUI options.
32-bit LispWorks requires about 160MB to install, and 64-bit LispWorks needs 180MB. This includes 110MB of documentation.
The documentation includes printable PDF format manuals. You may delete any of these that you do not need. They are available at
www.lispworks.com/documentation
in any case, and the same manuals are also available there in PostScript format.
