swap (or new swapint) is placed inside Adafruit_GFX library (file Adafruit_GFX.h)

download this lib and change:
from

Code: Select all#define swap(a, b) { int16_t t = a; a = b; b = t; }

to

Code: Select all#define swapint(a, b) { int16_t t = a; a = b; b = t; }

Thyanks very much again.

In my GFX_Library swap was defined as adagfxswap.
So I changed your swapint to adagfxswap. Now it is compiling without errors
Thanks

I see latest commit for it on adafruit github

tnx @canedje for info
now I fixed my version of lib for compatibility with Adafruit_GFX:

Edit2:
seems like that latest Adafruit_SSD1306 works too without any changes inside lib (but with little tuning inside included examples)

It's working fine now.
The display is showing what i want.
I'm happy.

I do have an additional question.
What is the command to draw a line?
