Release Notes for Clozure CL 1.7
Clozure CL 1.7 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)
- Solaris (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 on x86, one would run the following command from a shell prompt:
$ svn co http://svn.clozure.com/publicsvn/openmcl/release/1.7/darwinx86/ccl
Versions for other platforms are available by changing 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).
Please use the Trac instance at http://trac.clozure.com/ccl to review existing bug reports and to submit new ones.
The 32-bit Windows lisp now runs on 64-bit Windows.
The 64-bit Windows lisp kernel now builds with (and requires) a recent version of the mingw-w64 toolchain. See WindowsNotes.
An ARMv7 processor is now required. There have been a great many improvements and bug fixes to the ARM port since it was first released in version 1.6.
Mac OS X
Support for Mac OS X running on PowerPC has been dropped. Linux on PowerPC is still supported.
The interface databases for Mac OS X are now built from Snow Leopard (10.6) headers. This required the use of an experimental version of the interface translator that recognizes C blocks. See BuildFFIGEN.
The FreeBSD binaries were 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
New exported symbols
The following new symbols are now exported from the CCL package:
- dparef, sparef
- allow-heap-allocation, heap-allocation-allowed-p, allocation-disabled (r14807, ARM only)
When ccl:*disassemble-verbose* is true, the x86 disassembler will print the opcode bytes along with the disassembled instructions.
The macros dparef and sparef are shorthand for paref of :double and :float arrays. For example, (dparef p 3) => (paref p :double 3).
The image and fasl file versions have changed. Old heap images and fasl files won't work with 1.7.
The bundled version of ASDF is now 2.016.
asdf-install is no longer bundled. (See http://www.quicklisp.org/ for an alternative.)
In previous versions of CCL, *gensym-counter* was thread-local. It is now global, which means that gensym will produce lisp-wide unique symbol names. This implies, however, that user code that modifies *gensym-counter* must arrange to serialize access to it in some way. See http://trac.clozure.com/ccl/ticket/799 for discussion.
Further code coverage improvements.
An obscure low-level change: On Unix-like systems, we now have the operating system restart system calls interrupted by the signal used to suspend a thread. (The GC suspends all other threads every time it runs, so this is not rare.) We don't foresee any problems with this, but mention it here just in case.
Fee-based support for Clozure CL is available from Clozure Associates on a per-incident or contract basis. Please send mail to business@… for more information.
