Exception in: flat namespace

Hi,

I have a small root application (compiled) which runs fine on linux systems but not on my new Mac Pro. The gcc compiler on Mac is: i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5659).

The code is compiled OK but breaks down when I execute it. The errors are the following:

dyld: Symbol not found: __ZN14TVirtualFitter8SetCacheEii   Referenced from: /software/root/lib/libHist.so   Expected in: flat namespace
 in /software/root/lib/libHist.so
Trace/BPT trap

Any hints on the errors?

Thanks,
Xiaochun
