I just installed sbcl-1.0.36 on a 64 bit machine, and noticed that Ctrl-c doesn't interrupt computations that take too long for my patience. Is there any workaround for this? Many thanks, Martin

Are you using it inside Emacs/SLIME or some kind of wrapper library? Tamas This is SBCL 1.0.36, an implementation of ANSI Common Lisp.

Oh, sorry, that means the problem is elsewhere (I did try it on the command line, but my test was not good, obviously) > Are you using it inside Emacs/SLIME or some kind of wrapper library? Yes, I built FriCAS (a computer algebra system, cc-ing to that list) with it. I checked: martin(a)bustopherjones:~$ fricas Checking for foreign routines AXIOM="/home/martin//lib/fricas/target/x86_64-unknown-linux" spad-lib="/home/martin//lib/fricas/target/x86_64-unknown-linux/lib/libspad.so" foreign routines found openServer result 0 FriCAS (AXIOM fork) Computer Algebra System Version: FriCAS 2010-01-08 Timestamp: Friday March 5, 2010 at 12:34:46 ----------------------------------------------------------------------------- Issue )copyright to view copyright notices. Issue )summary for a summary of useful system commands. Issue )quit to leave FriCAS and return to shell. ----------------------------------------------------------------------------- (1) -> (1) -> )lisp (tagbody top (go top)) and pressing Ctrl-c doesn't "work" anymore. Curiously, when suspending with Ctrl-z, I indeed return to the shell, but the process keeps consuming 100% cpu! Many thanks for clarifying the source of the trouble! Martin |
