In order to build a runtime system for distribution on a target machine,
the option --moveable must be passed to
spld from hardcoding any (absolute) paths into
the executable. As of release 4.2, --moveable is the default on
most platforms, including Linux, Mac OS X and Solaris.
Next, in order for SICStus to be able to locate all relevant files, the following directory structure should be used.
myapp.exe sp-4.4.1/ +--- libsprt4-4-1.so +--- sicstus-4.4.1/ +--- bin/ | +--- sprt.sav +--- library/ +--- <files from $SP_PATH/library>
If support for multiple SICStus instances is needed, then the runtimes named e.g. libsprt4-4-1_instance_01_.so need to be available as well, in the same place as libsprt4-4-1.so.
If SICStus Prolog is installed on the target machine, then a symbolic link named sp-4.4.1 can be used, in which case it should point to the directory of the SICStus installation that contains the libsprt4-4-1.so (or equivalent).
If the runtime system needs to be debugged, then the above file system layout should be complemented as follows: The file spds.sav from the development system should be copied and placed in the same folder as sprt.sav and the license information must be made available. See Debugging Runtime Systems for details.
myapp.exe is typically created by a call to
% spld --main=user --moveable […] -o ./myapp.exe
On most platforms, the above directory layout will enable the executable
to find the SICStus runtime (e.q., libsprt4-4-1.so) as well as the
boot file sprt.sav (spre.sav). In addition, application
specific files, e.g. a .sav file, can be found using the
automatically set system properties
SP_RT_DIR. On some platforms a wrapper script, generated by
spld, is needed to ensure that the files are found.
Unless the --static option is passed to
spld, it might also be
necessary to set
LD_LIBRARY_PATH (or equivalent) to
/home/joe/lib (in the example above) in order for the dynamic
linker to find libsprt4-4-1.so. If the --static option is used,
then this is not necessary. Setting
LD_LIBRARY_PATH is not recommended
unless it is really needed.
When a runtime system is redistributed to third parties, only the following files may be included in the distribution. All filenames are relative to <prefix>/lib/sicstus-4.4.1:
Please note: you cannot redistribute spds.sav or license.pl.
