integer to ascii (itoa) usage or equivalent

[TeMa_1467596]

I've searched and read other threads in this forum but I can't get this to be recognized. I want to take an ADC result and convert it to a string so I can send t out over UART.

   

itoa seems not to be recognized.

   

I'm in PSoC creator 4.1 and the compiler is GCC 4.1.0.2686

   

Thanks in advance.
