Even if their code compiles and executes well, developers may receive an overwhelming number of Error Insight notifications while using C++ Builder 12.1P1. Incorrect library paths or conflicts between IDE features like Visual Assist and Error Insight are frequently the cause of this. These misleading errors can be reduced by modifying the environment settings and making sure namespaces are used correctly. Writing unit tests also aids in confirming that the code runs correctly despite the error messages displayed by the IDE.
