This section contains some installation notes that are platform specific under UNIX.
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).
Problems causes by the old thread library include:
library(timeout) does not work.
SICStus object.
This problem does not affect Solaris 9 or later.
An executable built with spld will only work if there is a properly configured subdirectory sp-4.0.8 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), this should happen 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
6144
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
unlimited
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.
As of SICStus 4.0.1 SICStus will set the data segment size of itself according to the value of the environment variable SP_ULIMIT_DATA_SEGMENT_SIZE. If you set this variable in the initialization file for your shell you do not have to use the ulimit command.
library(timeout) does not work reliably in some versions of Mac OS X 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). It seems to
be fixed in Mac OS X 10.5.2 (Darwin 9.2.2).
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.
The SICStus binaries are not built as universal binaries, and neither spld nor splfr supports building universal binaries. You can however build a universal binary of your SICStus application by running spld from a SICStus PowerPC-installation (this may be done on an Intel-Mac using Rosetta) and running spld from a SICStus Intel-installation, and then joining the two generated binaries with lipo. The following example assumes that your program is in myprog.pl and the paths to your PowerPC-installation and your Intel-installation are SP-i386-BINPATH and SP-PPC-BINPATH respectively:
$(SP-i386-BINPATH)/sicstus -l myprog.pl --goal "save_program(myprog), halt."
$(SP-i386-BINPATH)/spld --main=restore myprog.sav -static -o myprog-i386
$(SP-PPC-BINPATH)/spld --main=restore myprog.sav -static -o myprog-ppc
lipo myprog-i386 myprog-ppc -create -output myprog
You cannot install a PowerPC-based SICStus on an Intel-Mac with the
SICStus Installer Tool. You must unpack the tar file and run the
script InstallSICStus with the --all-questions
argument. When asked if you want to install the prebuilt version
of SICStus, answer “yes”.
