How to log a message from a string variable in Unreal Engine?


I am trying to log a message form a string variable , below is the code I used

std::string s = "ss";//std::to_string(FPaths::GetPath("../"));
 UE_LOG(LogTemp, Warning, *s);

but it's not working, Can someone tell me how to do this ? enter image description here


Solution

  • Finally I am answering my own question here.

    It doesn't compile because I need to use the TEXT Macro before giving a string into UE_LOG.

    FString s = "ss";
     UE_LOG(LogTemp, Warning, TEXT("%s"), *s);
    
     //or
    
     UE_LOG(LogTemp, Warning, TEXT("ss"));
    
     //this should work
     UE_LOG(LogTemp, Warning, TEXT("%s"), *FPaths::GetPath("../"));
    

    should work with Unreal's version of Datatypes instead of using the std library
