Release notes for Clozure CL 1.8
Clozure CL 1.8 runs on the following platforms:
- Mac OS X 10.5 and later (x86, x86-64)
- Linux (x86, x86-64, ppc32, ppc64, armv7l)
- FreeBSD 6.x and later (x86, x86-64)
- Microsoft Windows XP and later (x86, x86-64)
The preferred way to get Clozure CL is via Subversion. For example to get CCL for Mac OS X running on x86, one would run the following command from a shell prompt:
$ svn co http://svn.clozure.com/publicsvn/openmcl/release/1.8/darwinx86/ccl
For other platforms, change the darwinx86 to one of linuxx86, freebsdx86, solarisx86, windows, linuxppc, or linuxarm.
Both 32 bit and 64 bit binaries are included with all versions (except for ARM, which is 32 bit only).
For more details, please see SystemRequirements.
Please use the Trac instance at http://trac.clozure.com/ccl to review existing bug reports and to submit new ones.
Mac OS X
The Cocoa-based IDE requires Mac OS X 10.6 or later. The command-line lisp still runs on Mac OS X 10.5.
On Mac OS X 10.7, the AltConsole? application may not automatically activate when the standalone Clozure CL.app crashes. Clicking on the AltConsole? icon in the dock will activate it and it should then behave normally.
The binaries are built on a FreeBSD 8.1 system. If you are running 6.x or 7.x, you should be able recompile the lisp kernel on your own system and run the lisp without any further trouble:
$ cd ccl/lisp-kernel/freebsdx8632 # or freebsdx8664, as appropriate $ make
If you have an older system, the lisp kernel binary may fail to run, complaining that it's linked against an unavailable version of glibc. The release binaries are built on a Debian 5.0 system so this shouldn't affect many people, but if it does this fix is simple:
$ cd ccl/lisp-kernel/linux8632 # or linux8664 $ make
An ARMv7 processor is required. This unfortunately rules out several interesting small ARM-based systems. One such system is the Raspberry Pi, which uses an ARMv6 architecture chip (namely a ARM1176JZFS core), and will therefore not run CCL.
The nomenclature used to identify various ARM processors is extremely confusing. http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores may be of some help.
The IDE can communicate with a remote lisp process via a new protocol named "swink". (The verb "to swink" means to toil or to slave.)
The variable ccl:@, which is set by the inspector to the object being inspected, is available in the listener.
"CCL" is now a special Objective-C word, so that names like "ccl-application" will be translated to "CCLApplication". This prefix is reserved for CCL's own private use.
The function execute-in-gui was rewritten to use a different method of thread synchronization.
New exported symbols
The following new symbols are now exported from the CCL package:
On Unix-based systems, the HOME environment variable is now used by default to initialize user-homedir-pathname. This is optional: set ccl:*trust-paths-from-user-environment* to nil to disable this.
Minor incompatible change: the lisp kernel no longer treats a single command-line argument as an image name. This enables users to avoid writing a shell script wrapper for simple "standalone binaries" in some cases.
In certain cases, case and similar constructs compile into a jump table and therefore execute in constant time.
The bundled version of ASDF is now version 2.20.
