In same thread of discussion, for accessing non-virtual public functions of C++ class of dynamic library which will be loaded at runtime, Greg suggested following way:
Another possible strategy is to wrap the libopbx.dylib
's non-
virtualclasses in your own virtualized wrapper library, with libopbx.dylib linked
as a dependent library of the wrapper. Then your main app would weak-link
to your
virtual classes in the wrapper, and your virtualized wrapper would
"hard-link" to libopbx.dylib. This would free your main program from
direct dependence on libopbx.dylib, by moving that dependence to an
intermediary. This is essentially the Proxy design pattern.

I know requirement of declaring C++ class public member function as Virtual for accessing them (explained by Alastair in other thread of discussion), but still searching that is there any way exist for accessing non-virtual public functions from runtime loaded library.
Greg, can u elaborate this in detail or is there any other way exist?
Thanks,
Palav

don't support
10.2 now anyway.
