[chord] Error while make

[Roy Roemaat]

Hello,

I followed the steps in de Chord-Howto but i came till the make process
of chord. There I get an error.

....
In file included from server.C:36:
block_status.h:9: error: friend declaration requires class-key, i.e.
`friend
   struct block_status_manager'
make[2]: *** [server.o] Fout 1
make[2]: Leaving directory `/usr/src/sfsnet/dhash'
make[1]: *** [all-recursive] Fout 1
make[1]: Leaving directory `/usr/src/sfsnet'
make: *** [all] Fout 2
.......

Does someone know how to solve this error?

Regards,

Roy
