[chord] a chord question

[jungao at cs.cmu.edu]

Hi,

This is Jun Gao at CMU. We are trying to use Chord in our project. I had a
couple questions which bothered me for a couple days now.

(1) We were able to follow the instructions on the Chord page to download 
chord/sfs package and compile it on our machine. 

I ran into rather weird problem when I ran the "lsd" program. 
It appeared to be working correctly for the first few times, and we can 
test with "dbm" etc.  Today, however, I always got this following error 
when I start the first node:

lsd:  1055384135:592731 Higher-level RPC Failure 2
69ecbdb13c0aefc64f71d7b2fa3c9ab16e88917: join RPC failed: RPC: Unable to
receive

(see details below)

When I set the ACLNT_TRACE and ASRV_TRACE variable, I saw it says something
about unknown node? 

Can someone give us some clue what may be happening?


(2) Another question we have is when use the configure file generated by 
the setup program in Chord, it always complains something about

[jungao at yucatan chord-build]#../sfsnet/configure --with-db3 --with-sfs=../sfs-build 

...

../sfsnet/configure: line 1478: syntax error near unexpected token
`PKG_CHECK_MODULES(GSTUFF,'

...

Because of this, we are not able to compile vis. (We had to comment the
corresponding line out to finish compilation of other parts.)


Thank you very much for your help. 

Best,

-Jun


P.S. the detailed output
