- Weak_symbol abstract "A weak symbol denotes a specially annotated symbol during linking of elf object files. By default, without any annotation, a symbol in an object file is strong. During linking, a strong symbol can override a weak symbol of the same name. In contrast, 2 strong symbols that share a name yield a link error during compile-time. When linking a binary executable, a weakly declared symbol does not need a definition. In comparison, (by default) a declared strong symbol without a definition triggers an undefined symbol link error.Weak symbols are not mentioned by C or C++ language standards; as such, inserting them into code is not very portable. Even if two platforms support the same or similar syntax for marking symbols as weak, the semantics may differ in subtle points, e.g. if weak symbols during dynamic linking at runtime lose their semantics or not.".
