@ -4,7 +4,8 @@ Missing Key Function
If your build failed with a linker error something like this::
foo.cc:28: error: undefined reference to 'vtable for C'
the vtable symbol may be undefined because the class is missing its key function (see https://lld.llvm.org/missingkeyfunction)
the vtable symbol may be undefined because the class is missing its key function
(see https://lld.llvm.org/missingkeyfunction)
it's likely that your class C has a key function (defined by the ABI as the first
non-pure, non-inline, virtual function), but you haven't actually defined it.
