3.2 Platform Specific Notes

This section contains some installation notes that are platform specific under UNIX.

Solaris SPARC 64-bit
You cannot install (or build) the 64 bit version of SICStus using gcc 2.x. You need to use the Sun Workshop/Forte compiler, version 5.0 or later. InstallSICStus will try to find it during installation but if that fails, you can set the environment variable CC to e.g. /opt/SUNWspro/bin/cc before invoking InstallSICStus. Using gcc 3.x does seem to work but has not yet received much testing. To install with gcc 3.x, set the environment variable CC appropriately before invoking InstallSICStus.

The following libraries are not supported: library(bdb), library(tcltk).

Solaris 8
Library timeout does not work with the default thread implementation in Solaris 8. Instead the “Alternate Thread Library (T2)” must be used. This is ensured automatically for executables built with the spld tool. See http://developers.sun.com/solaris/articles/alt_thread_lib.html for further information.

This problem does not affect Solaris 9 or later.

Mac OS X

An executable built with spld will only work if there is a properly configured subdirectory sp-4.0.0 in the same directory as the executable; see Runtime Systems on UNIX Target Machines.

Alternatively, the option --wrapper can be passed to spld. In this case a wrapper script is created that will set up various environment variables and invoke the real executable.

When using third-party products like BDB, you may need to set up DYLD_LIBRARY_PATH so that the Mac OS X dynamic linker can find them. When using the SICStus development executable (sicstus), a wrapper script does this automatically.

Sometimes, the default limit on the process's data-segment is unreasonably small, which may lead to unexpected memory allocation failures. To check this limit, do

          tcsh> limit data
          datasize 	6144 kbytes
          bash> ulimit -d

This indicates that the maximum size of the data-segment is only 6 Mb. To remove the limit, do

          tcsh> limit datasize unlimited
          datasize 	unlimited
          bash> ulimit -d unlimited
          bash> ulimit -d
Please note: limit (ulimit) is a shell built-in in csh/tcsh (sh/bash). It may have a different name in other shells.
Please note: The limit will also affect SICStus when started from within Emacs, e.g. with M-x run-prolog. To change the limit used by Emacs and its sub-processes (such as SICStus) you will need to change the limit in the shell used to start Emacs. Alternatively you can create a shell wrapper for the emacs command.

library(timeout) does not work reliably when Mac OS X runs on a multi-CPU machine. In particular, timeouts tend to happen much later than they should. This is caused by an OS bug. One workaround is to disable all but one CPU using the “Processor” control in the “System Preferences” or the hwprefs command. These utilities are part of “CHUD” which can be installed as part of Apple XCode. The underlying bug is related to setitimer(ITIMER_VIRTUAL) and has been observed at least up to Mac OS X 10.4.8 (Darwin 8.8.1).

File names are encoded in UTF-8 under Mac OS X. This is handled correctly by SICStus.

If SICStus encounters a file name that is not encoded in UTF-8, it will silently ignore the file or directory. This can happen on file systems where files have been created by some other OS than Mac OS X, e.g. on network file servers accessed by other UNIX flavors or Windows.

The default character encoding for the SICStus standard streams is based on the current locale which is POSIX/C, i.e. US ASCII, by default on Mac OS X. This will come in conflict with the default character encoding for the Terminal application which is UTF-8. A clickable launcher for SICStus is optionally installed in the Applications folder. This launcher will set the character encoding of the standard streams to UTF-8 for both the Terminal and SICStus.
