[Swarm-Support] Swarm on Mac

[David Camacho Trujillo]

Dear Swarmers,

I use to work with Swarm under Linux, (some time under windows) and my model
runs fine. Recently I have installed Swarm on a Intel Mac (Intel Core Duo)
following the instructions on the wiki (many thanks to Bill Northcott, I just
will suggest to include the prerequisite of run X11 before run any application,
as you already explain in this mailing list) and the swarmapps runs fine also.
But now my application (Objective-c code) does not compile.
The output is:

make gamodel
gcc -B ../../tools -c -g -O2 -Wno-long-double -B /tools -fgnu-runtime
-fno-strict-aliasing -Wall -Wno-import -Wno-protocol -Wno-long-long  -arch ppc
-D_GNU_SOURCE -DAPPNAME= -DAPPVERSION=2.2 address@hidden  
-I/usr/local/swarm2.2/include  BinChrom.m

make: *** [BinChrom.o] Error 1

I am not really sure where to start looking at the problem, so I really
appreciate any advise. ( I am new to Mac´s) 
I have :
System Version: Mac OS X 10.4.8 (8N1150)  (Tiger)
Kernel Version: Darwin 8.8.3
Thanks in advance,
David
