Identifier "typeid" is undefined problem

Hello,

I try to compile following code. But mbed compiler say ""Identifier "typeid" is undefined" in file "/main.cpp", Line: 12, Col: 1"

Can't current mbed compiler use typeid?

sample

#include "mbed.h"
#include <typeinfo>
DigitalOut myled(LED1);

class A
{
};

int main()
{
    A a;
    if(typeid(a)==typeid(A)){
        myled=1;
    }
    
}

Hello Ryo lizuka,

RTTI is disabled by default which typeid requires. You can export it to any offline tool and turn RTTI back on. Your example compiles without error with rtti compiler option set.

Hello Martin-san,

Thank you for response.

It was possible to compile by previous mbed compiler. I want to know whether the problem is temporary or not. Do you know the information for that?

Regards.

I have this same problem. It only started occurring on Friday afternoon.
