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 ?

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

You can accept your own answer if it's correct :P And try to use Unreal's string, array, map...etc. instead of std ones since Unreal has its own magic...

Only the std algorithms are compatible with Unreal's containers since they support begin() and end(), otherwise I think you should use Unreal's equivalents.

UE_LOG(LogTemp, Warning, TEXT("%s"), *s); 🤦If you really have to than you can convert std::string to FString and than log that like this.
std::string someString = "Hello!";
FString layerName(someString .c_str());
UE_LOG(LogTemp, Warning, TEXT("%s"), *layerName);
