Re: [Swarm-Support] gcj - swarm - exe

[Paul E. Johnson]

The last time I fiddled with this, I wrote directions on compiling swarm 
programs
with swarm-gcj here:

http://lark.cc.ku.edu/~pauljohn/Swarm/Swarm-2.x_RPMSforRH7/


On August 12, 2003 Marcus Daniels posted a note called "Pretest 8" which 
announced a new MS Windows/Cygwin package,
and in there he mentioned that he followed this route to use gcj.

"
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
"

It seems to me that the only difference is that this one sets 
LTDL_LIBRARY_PATH rather than LD_LIBRARY_PATH
