An overview of system requirements is provided in System requirements on FreeBSD. The sections that follow discuss any relevant details.
LispWorks 7.0 for FreeBSD requires that the X11 release 6 (or higher) is installed.
LispWorks 7.0 also requires that either GTK+ or Open Motif with Imlib are installed.
The remainder of this section contains the details for each of these distinct GUI options.
In order for the LispWorks IDE to run "out of the box", GTK+ must be installed on the target machine.
Open Motif version 2.2 or higher is required to run LispWorks with the Motif GUI.
Install Open Motif 2.2.x from the FreeBSD distribution or ports tree. Your systems administrator may be able to help if you do not know how to do this.
You will also need Imlib (not Imlib2). Install this from the FreeBSD distribution or ports tree. Imlib version 1.9.13 or later is recommended.
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.
