We have a customer complaining that the --wrap option to ld (again,
2.12.1) doesn't work with C++. Would I be correct in assuming that
this is because of the C++ name mangling? If so, is there anything
(other than extern "C") that they can do to make it work?
--wrap should work fine with C++. However, you do have to mangle the
names yourself, and use --wrap with the mangled name.
There is no real alternative. It is not practical for the linker to
incorporate a C++ mangler, particularly as different compilers, even
different versions of g++, use different mangling schemes.
