[Swarm-Support] errors compiling jheatbugs bytecode with gcj after javaswarm fails in initSwarm

[Tim Howe]

Greetings ...

 

I get these errors when I try to compile the bytecode for jheatbugs-2001-03-28 using gcj:

 

/Swarm-2.2/lib/libgcj.a(natInflater.o)(.text+0x88): In function `_ZN4java4util3zip8Inflater3endEv':

Can you tell me how to fix these errors?

 

Here's how I got to this point: I was able to run Swarm (for example, jheatbugs-2001-03-28) for a long time. Then I upgraded from cygwin.dll 1.5.5-1 to 1.5.10-3. That seemed to kill Swarm; when I invoke jheatbugs through javaswarm, it dies silently in initSwarm(). Next I followed this advice, which I found at http://www.swarm.org/pipermail/support/2004-May/014150.html: 

There is something wrong with the java swarm and the current version of
Cygwin. However, it is easy to get around this. Just follow the steps
below and you should be able to run any java swarm application.
1. Compile your code using javacswarm
2. Compile your bytecode using gcj. The command you have to write to
compile jheatbugs is($ is the prompt):
$CLASSPATH=/Swarm-2.2/share/swarm/swarm.jar gcj --main=StartHeatbugs
*.class /Swarm-2.2/lib/gcj*.o -L/Swarm-2.2/lib -o jheatbugs
3. Run your application by typing:
$LTDL_LIBRARY_PATH=/Swarm-2.2/lib ./jheatbugs

-Vegard

Using that gcj command, I got errors, some of which I eliminated by installing 
Devel - gcc-Java and Libs - libiconv. The Cygwin libraries I have installed by 
explicit request are now libiconv 1.9.2-1, libpng12 1.2.5-4, and tcltk 20030901-1 
(all are the current Cygwin versions as of Aug 3 2004). 
 
I use the following script to run gcj. The result is the same (shown at the top of this message)
whether I use -specs=/cygdrive/d/cygwin/lib, or /cygdrive/d/cygwin/lib/mingw, 
or Swarm-2.2/lib, or (as in Vegard's posting) no -specs option at all.
