Yes, sort of.
ELF makes it a bit easier. If a C program is using C linkage to a C++
shared object, all will be just fine so long as the C++ shared object was
linked to any necessary shared object dependencies (libsupc++, libgcc_s,
and/or libstdc++). This is normally accomplished by using "c++ -shared" to
link the C++ shared object.
Ideally, and in most cases, ELF dependencies would take care of that, so the
C program need only link or dlopen() the C++ shared object.
