2 problems running Heatbugs

[jones . peter]

Dear Swarm-Support:

I am able to install Swarm in the following situation:

RedHat Linux 7.0.1 on an Intel platform, with all current updates
gcc 3.0.1 (using a CVS archive), installed in /usr/local/gcc3
Blackdown Sun JDK 1.3.1 
HDF5 installed at /usr/local/hdf5

Swarm itself is installed at /usr/local/swarm.


When trying to run heatbugs, I have two problems:

1) I am getting 11 warnings about dynamic symbols, once in the
"make", and again for each execution of the compiled program.
They appear to be related to entries in HeatbugObserverSwarm.h
and HeatbugObserverSwarm.m.

Is there a way to avoid these warnings?


2) In order to compile, I seem to have to specify
EXTRALDFLAGS="-rpath /usr/local/gcc3/lib". Otherwise, if I specify
only the SWARMHOME directory, the make appears to succeed, but
running heatbugs itself gives the diagnostic:
lt-heatbugs: error while loading shared libraries: libgcc_s.so.1: cannot load 
shared object file: No such file or directory
I feel this flag is burdensome for end-users, but it will go away
when gcc3 becomes the standard compiler. Probably it would not
occur if I stuck to the standard gcc compiler. If Swarm needs
libgcc_s.so.1, then it should set this flag. Otherwise, I agree
it's the end-user's responsibility; maybe this flag could be set
in the makefile.


In a correct execution, I cd to the heatbugs directory, and type:
make SWARMHOME=/usr/local/swarm EXTRALDFLAGS="-rpath /usr/local/gcc3/lib"
giving:

creating heatbugs

Then, 
./heatbugs
gves the same 11 warnings, but the simulation runs.
