[Swarm-Support] Pretest 8

[Marcus G. Daniels]

Hi,

I've just put up 
ftp:/ftp.santafe.edu/pub/swarm/binaries/w32/latest/Swarm-2.2-pretest-8.tar.gz. 


This is the latest build of Swarm with the addition of a build of GCC 
3.3.1, the latest
stable release of GCC.  This build of GCC 3.3.1 includes a build of the 
GCJ compiler and libraries, with some bug fixes to make dynamic linking 
[of the Swarm libraries]  work with Cygwin.

To use GCJ to build Swarm executables of Java Swarm models, you can add 
rules like this to your model implementation Makefile:

Here's an example for Java heatbugs:   (one line)

CLASSPATH=/Swarm-2.2/share/swarm/swarm.jar gcj -O2 -g 
--main=StartHeatbugs -L/Swarm-2.2/lib *.class 
/Swarm-2.2/lib/gcj_{swarm,gnubytecode}.o -o jheatbugs

Then you will need to inform the dynamic linker as to the location of 
the libraries:

export LTDL_LIBRARY_PATH=/Swarm-2.2/lib

Finally, run it:

./jheatbugs

Btw, there are still problems making recent Cygwin DLLs and Sun JDK 
place nice.   I've figured out what some of the conflicts are, but some 
remain.  A good thing to do would be to make the Java Swarm DLL builds 
not dependent on the Cygwin DLL.
