error trying to compile ssd1306_128x64_i2c

after downloading the ssd1306 master library and fixing the height error

(found here https://forum.arduino.cc/index.php?topic=364400.0)

I tried to download the program to my Arduino and got the error message “include adafruit_gfx.h”. after downloading that code and adding it to the library, I was met with the error “include gfxfont.h”, so i downloaded that code and added it to the library as well.

now when I try to download the code to my Arduino I get what you see in the attached picture.

I am new to this but is seems the problem is in the adafruit_gfx.h code. All the undefined references (setTextcolor, height() const, etc.) seem to come from there

(for reference: Adafruit-GFX-Library/Adafruit_GFX.h at master · adafruit/Adafruit-GFX-Library · GitHub)

please advise, thanks.

You have to copy and paste the error message in a code window with the </> icon. A screen dump is useless. Also post the code you are trying to run so we can try it as well.
