Error when compiling for ESP32

[LennartHennigs]

Hey,
I get the following errors when I try to compile a program for the ESP32 Dev C module:

Do you have any suggestion on how to fix this?

Cheers

(...and since you asked in the README: it works fine on the Ardudino Nano! )

At the moment the library makes the assumtion that the esp32 dev compiler has a working implementation of the std.
I guess properly chacking if there is an std implementation is the proper way to go.
I will try to fix this but it should not be that hard to fix.

I found the issue can you check if it works now?

[LennartHennigs]

Wow that was fast.
And yes, it works! Thanks a lot!
