I found the problem. I make a mistake that make a fault sym-link to a
old library..... -_-;

By the way, I 'ven't install Kaffe. I re-compile the Swarm and now I can
compile the jheatbugs with "make".

However, I can't run it... I've tried:

(1)
# javaswarm StartHeatbugs
Error: could not find Java 2 Runtime Environment.

(2)
# java StartHeatbugs
Exception in thread "main" java.lang.NoClassDefFoundError:
swarm/simtoolsgui/GUISwarmImpl

(3)
# java -cp "./:/usr/local/share/swarm/swarm.jar" Start Heatbugs

Do I make anything wrong again? (sure....)

Yes, I use Sun JDK 1.3.1. Here are some log come from my compilation:

Those messages appear near the end of my compilation. I also noticed
that there is a error : could not find Java 2 Runtime Environment too.

Sorry. I show them here:
1. In libobjc/objc/hash.c, it complain that it can't find the "strncmp"
function. So I add a include header <stdio>, <stdlib>, <string> into it.

2. In libobjc/objc/Protocol.h, the last #endif have a extra token after
it, remove it.

3. In src/activity/, the "make" will run a srcipt called "make-h2x" to
produce a .xm file. The activity.xm file gen. out seems have problem
(may be a bug in make-h2x). Some lines in activity.xm seems wrong and
should not be there. I remove these lines:
#481 "./activity.h" (several this kind of line)
typedefunsignedlonginttimeval_t=0

then "make" it again.

Hope my information is usful. Thanks for reply.

Best regards,
