[Swarm-Support] Execution error of heatbug application on Snow Leopard

[Cristiano Fontana]

Hello,

I successfully compiled swarm v 2.3 on my Mac (version 2.2 did not want to).

I then tried to run the heatbug application without success.
I compiles with some warnings like:

        /usr/bin/gcc-4.2 -c -O2 -arch x86_64 -B /tools -DH5_USE_16_API 
-fnested-functions -fgnu-runtime -fno-strict-aliasing -Wall -Wno-import 
-Wno-protocol -Wno-long-long  -I/opt/local/include -D_GNU_SOURCE 
-DAPPNAME=heatbugs -DAPPVERSION=2.1.1 address@hidden   -I/opt/local/include  
HeatbugModelSwarm.m 
        HeatbugModelSwarm.m: In function ‘+[HeatbugModelSwarm createBegin:]’:
        HeatbugModelSwarm.m:99: warning: receiver ‘CustomProbeMap’ is a forward 
class and corresponding @interface may not exist
        HeatbugModelSwarm.m: In function ‘-[HeatbugModelSwarm buildObjects]’:
        HeatbugModelSwarm.m:140: warning: receiver ‘Grid2d’ is a forward class 
and corresponding @interface may not exist

however it produces the executable.
But at the execution it crashes with:

        $ ./heatbugs
        objc[32102]: found old-ABI metadata in image 
/Users/fontana/Downloads/swarmapps-objc-2.2-2/heatbugs/./heatbugs !
        Version 0 doesn't match runtime protocol version 2
        Abort trap
 
This is my first time with ObjC so I do not know how to deal with this error.

        Thanks in advance,
        Cristiano
