I trying to do some recursive memory searches. I have run into a couple of searches which require large amounts of memory. I understand that CLISP has an option of -m to allocate more memory. On the NT side, It does not seem to work at all. On NT, I get about 2000 levels down before "Program Stack Overflow. RESET" regardless of the value by option -m. RedHat Linux seem to have a limit too. The -m10m gives me about 8000 levels, -m20m gives me about 9500 levels, and -m40m has the same limit as -m20m. How do I get more memory of CLISP to use? Or is there a bigger concept that I am missing? Thanks in Advance Randy |

For using large amounts of memory, use: clisp -W It's a bit slower, though. Ricardo. -------- mailto: "Ricardo Aler Mur" <al...@in...> http://scalab.uc3m.es/~aler |

Hello! I have been using clisp with a extension called clg (it let to use the gtk functions in lisp) and it runs OK but it doesn't free the lisp listener. I don't know if this is because the clg or the clisp. Can anyone know any about it? If it is because clisp, is there any function that set the listener free? Thanks Gerardo Sarria |

CLG does some magic with CMUCL to make sure that the listener is "freed". I do not know whether you could do the same with CLisp, although I suppose so.

On Windows, the stack size needed by a program must be hardwired in the executable (lisp.exe). On Unix, the maximum stack size is changeable through the 'ulimit' shell builtin; its use might require superuser privileges. Therefore all you can do is a) prefer iteration over recursion when you are iterating through long lists, b) compile your lisp programs, then they eat less stack, c) become superuser and use "ulimit -s" to change the stack size, then su back to your normal identity and start clisp.

Try increasing them using `ulimit' on linux+bash (don't know the NT equivalent). -- Eric Marsden <URL:http://www.laas.fr/~emarsden> |
