SIMSCRIPT II.5 release.
Note that ranlib is not available on all systems. On systems where it is not available it is
not needed. To link the object files in a directory with this library, enter:
% simld *.o –lxyz
A SIMSCRIPT II.5 program can call routines written in other languages, such as C or
FORTRAN. To link such a program, specify to simld (or simgld if the program makes
use of SIMGRAPHICS features) the name of each object file created by the other compiler,
along with the name of each object file created by the SIMSCRIPT II.5 compiler.
SIMSCRIPT II.5 supports two graphics systems SIMGRAPHICS I and SIMGRAPHICS
II. As of Release 1.9, SIMGRAPHICS II is the default SIMGRAPHICS in SIMSCRIPT
II.5 systems. Compiler switch -G will link graphical models with SIMGRAPHICS II
libraries.
simc -G *.sim
Also simgld will automatically link with SIMGRAPHICS II libraries. If you want to use
SIMGRAPHICS I, you must compile your model with the -c option and use simgld1 as
follows:
simc -c *.sim
simgld1 *.o
SIMSCRIPT II.5 runtime libraries as well as SIMGRAPHICS libraries are distributed in two
versions: dynamic link libraries and archive libraries. This facilitates dynamic and static
linking. By default programs will be linked dynamically.
When a model is linked dynamically, the executable image does not include the entire object
modules it needs for execution. It contains pointers to the dynamic link libraries also called
“shareable libraries”. The benefits of dynamic linking are twofold: first linking time is
shorter, second all SIMSCRIPT models in the same computer platform share the same
runtime libraries which results in substantial savings of disk space. When you use existing
link commands: simld, simgld, simgld1 and simgld2 your model will be linked
dynamically.
If you want to execute your model on some other platform, which does not have the same
release of SIMSCRIPT II.5, or does not have SIMSCRIPT II.5 installed at all, your model
must be linked statically. This means that you have to perform static link or “total link”. In
other words, your executable has to include all object modules in itself.
SIMSCRIPT II.5 provides commands for platform independent static linking or “total
linking” for both non-graphical and graphical SIMSCRIPT models:
tsimld
tsimgld
tsimgld1
tsimgld2
