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
