Re: GraphDemo

Hi Pietro!

Two possibilities:

1) Did you download the GraphLib directory into the src area of Swarm?
   There should be a libgraph.a (I think) in your .../swarm/lib area after
   you do a make of the GraphLib stuff.

2) Also, in the Makefile (of GraphDemo) there is a line which looks
   like this:

   APPLIBS=-lgraph

   And it is supposed to show up when you link the application:

  gcc -g -L../../swarm/lib -L/usr/X11R6/lib  -o bank FEntity.o FLink.o ILink.o
  BLink.o FNet.o main.o BankModelSwarm.o BankObserverSwarm.o BankBatchSwarm.o
    ../../swarm/lib/swarm.x -lobjc -lX11 -lm
  ^
 /|\
  |

 missing reference: "-lgraph"

Now, it seems that you are using a binary distribution of Swarm (hence the
swarm.x) and I have no experience compiling against the shrinkwrapped dist.
It may be that there is actually a bug with that, and that the APPLIB var
is being ignored (either that, or it is commented out of your makefile).

In any case try cut & pasting the final compilation line and inserting
-lgraph before the rest of the stuff, and see if that works...

Manor.

PS. Actually, I was just checking the Makefil.appl, and I notice this:

  ifeq ($(LDCONFIG),bin)
  APPLIBS=
  endif

Which could mean that if LDCONFIG is bin (i.e. this is a shrink-wrapped
distribution), then the system disallows application specific libraries,
(which would explain the lack of a -lgraph in you compilation). This is
a bit odd but I'm sure there's a reason for it... I think this is a
question for Glen :-)
