Incremental linking of new stars does not work in the Ptolemy 0.x NT
port.
The usual way of doing incremental linking is to build a binary
that is dynamically linked.
Currently, the Ptolemy 0.x NT port is statically linked. I was
unable to build a dynamically linked version.
The -fPIC option denotes Position Independent Code, which
is used to generate shared objects which can be loaded in at runtime.
Older versions of Ptolemy used the BSD ld -A option to load
stars into statically linked binaries, but that option is not
available in newer versions of ld.
The way I would figure out how to do incremental linking would be to
build a dynamically linked binary with the Microsoft Visual C++ port
(PTARCH=nt4.vc) and then port those changes to the Cygwin port.
This is a fairly big job.
With the cd2dat demo, it should be possible to build a binary that
had the appropriate stars built in, and then to create a new
simulation that used those stars. This sort of defeats the purpose of
this simulation though, since the cool thing is that it generates
a star on the fly that gets loaded in at run time. However, if
you were interested in the CD to DAT conversion, then this might
do the trick.

Hi,
I just finish the installation of Ptolemy 0.7.1 under Windows NT 4.0
with Cygwin32 Beta 19.1 with egcs 1.0.2. and I test it. But the demo
under
mixed Domains Demo --> SDF/CGC Combinations --> cd2dat don't seem to
work and I don't know how to resolve the problem.
when I want to run the demo, the message is the following:
rshCommand: mkdir -p $HOME/PTOLEMY_SYSTEMS/CGC
rcpWriteFile: writing file SDFcd2dat_compiled.sched
rcpWriteFile: writing file SDFcd2dat_compiled.pl

/users/ptolemy/obj.nt4/ptlang ; make ptlang VPATH=../../src/ptlang
>/dev/null 2>&1); fi; if [ ! -f /users/ptolemy/obj.nt4/ptlang/ptlang.exe
]; then echo ptlang; else echo /users/ptolemy/obj.nt4/ptlang/ptlang.exe;
