Using SoftI2C with INA219 (curent sensor) compiler errors

Greetings,

I'm trying to use felias-fogg excellent Soft I2C library

with Adafruits

https://github.com/adafruit/Adafruit_INA219

As instructed there, I replaced the

#include <Wire.h>

with

#include <SoftWire.h>
SoftWire Wire = SoftWire();

(also in the INA libray) but get a bunch of errors.

I tried some combinations of declaring in this or the other files s(.cpp, .h or .ino) but the compiler always complains.

I use all those three files in one folder, if that's of some importance here.

Arduino: 1.8.5 (Windows 7),
Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Can anybody help please?

Thanks!!
Attached the code and verbosed error messages

No one is going to open a zip file from an unknown source.
