Don't Panic! (older releases)

Known Bugs and Some Provisional Fixes SICStus 4.7.1

• Crashes on Windows 11 with 64-bit version of SICStus. This probably affects older versions of SICStus as well. This problem has been fixed in forthcoming 4.8.0.

  A workaround is to turn off the jit compiler, i.e. start SICStus with the system property SP_JIT set to disabled. One way to do this is:

   sicstus.exe -DSP_JIT=disabled
  

  You can also set the environment variable SP_JIT to disabled in the shell (or globally) before starting SICStus.

• Installer complains about missing config.sub file (SICStus 4.7.0 on Linux and macOS, fixed in 4.7.1).

  When doing a full install, i.e. not the default "pre-built" install, the installer will fail with a message similar to

  $ sudo ./InstallSICStus
  ...
  Configuring system. This may take a few minutes...
  Configuration phase failed. Output:
  configure: error: cannot run /usr/bin/sh ./config.sub
  ...
  Installation aborted.
  

  A workaround is to download the missing file into the same folder as where InstallSICStus is located, e.g.

  $ curl --output config.sub https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
  

  You can then start the installer again (it will remember your previous answers to any questions).
