15.5 GTK+ window system

LispWorks uses GTK+ as the default window system for CAPI and the LispWorks IDE on Linux, FreeBSD, AIX and x86/x64 Solaris. GTK+ is also supported on Mac OS X as an alternative to Cocoa. LispWorks requires GTK+ 2 (version 2.4 or higher).

Note: LispWorks on SPARC Solaris does not support GTK+.

A few known problems are documented on Problems with CAPI on GTK+.

15.5.1 Using Motif instead of GTK+

Use of Motif with LispWorks on Linux, FreeBSD, x86/x64 Solaris and Mac OS X is deprecated, but it is available by

(require "capi-motif")

To use LispWorks 7.0 with Motif you also need Imlib installed, as described earlier in this manual.
