C:\Users____\Documents\Arduino\libraries\VGA/VGA.h: In function 'void _v_digitalWriteDirect(int, boolean)':

C:\Users____\Documents\Arduino\libraries\VGA/VGA.h:49:11: error: 'g_APinDescription' was not declared in this scope

if(val) g_APinDescription[pin].pPort -> PIO_SODR = g_APinDescription[pin].ulPin;

       ^

C:\Users___\Documents\Arduino\libraries\VGA/VGA.h:50:11: error: 'g_APinDescription' was not declared in this scope

I had the same issue. The "'g_APinDescription' was not declared in this scope" error happens when the wrong board is selected in the Arduino IDE. In my version 2:1, I couldn't select the correct "Arduino Due (programming port)" for some reason. Instead I downloaded version 1.8 and was able to install and update the board through Tools > Boards > Board manager. After restarting the IDE and compiling, the code works perfectly. I have no idea why the correct "Arduino Due" doesn't appear in the version 2 of the IDE, but this fixed the issue anyhow.
