Re: Problems with Swarm on LinuxPPC

[SCHREIBER,DARREN MATTHEW]

I managed to get a similar error when I was compiling on my Win98 box at
work that uses Swarm 2.1.1.  I include the compilation report and the
output from nm main.o.

I found that this error was somehow connected to a failure of a previous
version of my model to properly quit.  I tried to force the model to quit,
but eventually had to reboot.  Upon reboot, the compile and run went just
fine.

I don't think an analogous problem could have happened on my Linux box
since I didn't get it to compile at all.  However, the errors look
similar.

Let me know if you have any ideas.  I will reply with the results from nm
main.o on my Linux box when I get home.
