In order to locate all relevant files, the following directory structure should be used:
myapp.exe sprt4-4-1.dll sp-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. sprt4-4-1_instance_01_.dll need to be available as well, in the same place as sprt4-4-1.dll.
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 […] -o ./myapp.exe
If the directory containing sprt4-4-1.dll contains a directory
sp-4.4.1, then SICStus assumes that it is part of a runtime system
as described in the picture below. The (extended) runtime library,
sprt.sav (spre.sav), is then looked up in the directory
(sp-4.4.1/bin), as in the picture. Furthermore, the initial
library_directory/1 fact will be set to the same directory with
The directory structure under
library/ should look like in a
regularly installed SICStus, including the platform-specific subdirectory
x86-win32-nt-4 in this case). If your application needs to use
library(random), then your directory
structure may look like:
myapp.exe sprt4-4-1.dll sp-4.4.1\ +--- bin\ | +--- sprt.sav +--- library\ +--- random.po +--- timeout.po +--- x86-win32-nt-4 \ +--- random.dll
sp* files can also be put somewhere else in order to be
shared by several applications provided the sprt4-4-1.dll can be
located by the DLL search.
Naming the files with version number enables applications using
different SICStus versions to install the
sp* files in the same
When a runtime system is redistributed to third parties, only the following files may be included in the distribution. All filenames are relative to %SP_PATH%:
Please note: you cannot redistribute spds.sav or license.pl.
Prior to release 4.4,
library(timeout) also used a foreign resource. This is no longer the case.
