RTTI won't build the project and throw errors

Development Programming & Scripting

n my code I need the typeof() function which need the rtti enabled but when I try to build my project it does not see the typeof function but when I include “bUseRTTI = true;” in the plugin build.cs file my project throw “/clang:-1: linker command failed with exit code 1 (use -v to see invocation)”

this is the plugin build.cs Code:
using UnrealBuildTool;

public class CryptoPPPlugin : ModuleRules
 {
    public CryptoPPPlugin(ReadOnlyTargetRules Target) :   base(Target)
    {
PCHUsage = ModuleRules.PCHUsageMode.UseExplicitOrSharedPCHs;

PublicIncludePaths.AddRange(
    new string[] {
        "CryptoPPPlugin/Public"

        // ... add public include paths required here ...
    }
    );


PrivateIncludePaths.AddRange(
    new string[] {
        "CryptoPPPlugin/Private",

        // ... add other private include paths required here ...
    }
    );


PublicDependencyModuleNames.AddRange(
    new string[]
    {
        "Core",

        // ... add other public dependencies that you statically link with here ...
    }
    );


PrivateDependencyModuleNames.AddRange(
    new string[]
    {
        "CoreUObject",
        "Engine",
        "Slate",
        "SlateCore",

        // ... add private dependencies that you statically link with here ...  
    }
    );

    // Turn on RTTI, support typeid()
    bUseRTTI = true;
    // support throw exception after opening
    bEnableExceptions = true;

DynamicallyLoadedModuleNames.AddRange(
    new string[]
    {
        // ... add any modules that your module loads dynamically here ...
    }
    );
    }
   }

Is there anything I need to do to make the rtti work in the project?!!

Why you need rtti for? you are aware UE4 already have extensive reflection system?
