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
