“internalsuu undefined symbol” typically occurs during dynamic linking when a symbol (function, variable, etc.) cannot be resolved in the shared library (DLL or SO). This can happen due to missing dependencies, incorrect library versions, or mismatched symbol tables. Dynamic linking allows for code reuse and modularity, while also improving performance by loading shared libraries only when needed. Internalsuu refers to symbols internal to a library and not exported, which can lead to undefined symbol errors when attempting to link to the library.
