Hi,

I think you need to add std:: namespace for the stoi function.

Hello,
This also doesn’t work. The compiler is behaving really strange, at some instance it compiles and at other, it comes up with errors.

Did you include <string> header file?

Yes , it was included right from the first attempt.

I think it is because the mbed2 build does not support c++11 feature.

It is compiling the same code in other file .
