Hi, In http://www.codesourcery.com/cxx-abi/cxx-closed.html#B7, the question of how to support C++ objects in shared memory is resolved by requiring "to force the objects, Vtables, functions, etc. to the same addresses in the various processes involved." How could this be done with GCC (specifically on Linux or Solaris if that is relevant)? Is it as simple as ensuring the executable text is in the same place? Or is some of the vtable data initialized at runtime? Any help much appreciated! Thanks Anthony This communication is for informational purposes only.
