Re: [Swarm-Support] compile error, now almost working

[Paul Johnson]

Well, I dunno about your build since you have not done it the way I do.

It looks like you have a typographical error, in the prefix you say 
"user" and in your compiler output it says "usr".

I hasten to say that if you did ./configure once and built swarm, then 
running ./configure --prefix will not do anything. You can erase the 
build dir to get a fresh start.

Also, I wonder if you noticed that when swarm installs, it gives lots of 
warnings about dynamic libraries and I suspect you have not taken into 
account the fact that your swarm libraris are not in your 
LD_LIBRARY_PATH. Consider setting the library path in the environment with

# export LD_LIBRARY_PATH=/home/user/swarm:$LD_LIBRARY_PATH

so it knows where to look.
