Release notes for Clozure CL 1.9
Clozure CL 1.9 runs on the following platforms:
- Mac OS X 10.5 and later (x86, x86-64)
- Linux (x86, x86-64, ppc32, ppc64, armv7l/armv6)
- 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 running on x86, one would run the following command from a shell prompt:
$ svn co http://svn.clozure.com/publicsvn/openmcl/release/1.9/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).
CCL's use of subversion depends on features introduced in subversion 1.5. Subversion clients for many platforms are available at http://subversion.apache.org/packages.html.
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 and later, 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.
CCL 1.9 is distributed with interfaces based on the OSX 10.8 (Mountain Lion) headers.
Apple's version of the GDB debugger can't be used to debug CCL 1.9 or later. In the event that you ever actually need to debug CCL at this level, slightly modified versions of Apple's GDB are available at http://ccl.clozure.com/FTP/gdb-768-limited-mach-exceptions.tar.gz (for OSX 10.5) and http://ccl.clozure.com/FTP/gdb-1820-limited-mach-exceptions.tar.gz (for OSX 10-6-10.8).
The binaries are built on a FreeBSD 6.3 system. If you are running a later version of FreeBSD, 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
The Linux/x86 binaries are built on a Debian 5.0 system. This is old enough that most people should not encounter any difficulty with running the lisp kernel binary. If, however, the provided binary fails to run, complaining that it is linked against an unavailable version of glibc, then you should be able to compile the lisp kernel on your own system and run the lisp without any further trouble:
$ cd ccl/lisp-kernel/linux8632 # or linux8664 $ make
Note that the m4 program needs to be installed in order to build the lisp kernel.
An ARMv6 or ARMv7 processor is required. 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 ARM Linux world has been transitioning between different sets of C function calling conventions; these changes have to do with how floating-point arguments and results are processed. Newer distributions (generally) tend to use the new "hard float" ABI; older distributions use the traditional "soft float" ABI, and some distributions can support both sets of conventions simultaneously.
The conventions that CCL uses depend on the options used to build the lisp kernel; the kernel build process will use the option specified in the file "ccl/lisp-kernel/linuxarm/float_abi.mk". As distributed, this file defines FLOAT_ABI as "softfp" (and a definition of FLOAT_ABI as "hard" is commented out.) To build a lisp kernel that uses the "hard-float" ABI:
1. cd ccl/lisp-kernel/linuxarm 2. (edit float_abi.mk so that FLOAT_ABI is defined as "hard".) 3. make clean 4. make
New exported symbols
