This is a SlackBuild that will install ccl (Clozure Common Lisp). Ccl includes both 32-bit and 64-bit binaries (except ARM which is currently 32-bit only). Official scripts 'ccl' and 'ccl64' will be put on PATH, corresponding to the 32-bit and 64-bit lisp implementations in order. On Slackware64 with multilib installed, it's possible to run 32-bit ccl, using 'ccl' instead of 'ccl64'. Ccl uses low 16 bits of the address space for certain optimizations. The Linux kernel provides a feature that can prevent a process from mapping addresses below a certain base address to prevent exploitation of undiscovered null pointer dereference bugs in the kernel. To make ccl run on Slackware, 'mmap_min_addr' will be set to 4096. (see /etc/sysctl.d/ccl.conf) The 4K value will protect against certain (yet-to-be-discovered) NULL pointer deference bugs in the kernel, but will still allow applications to use low-memory addresses. For details see http://trac.clozure.com/ccl/wiki/PlatformNotes To make ccl usable before a reboot, execute the command below; # /sbin/sysctl vm.mmap_min_addr=4096
