<![CDATA[T-RGB Example Compile Errors]]>I have the 2.1" Half T-RGB. I'm trying to load the GFX example through Arduino IDE. However, I keep getting the following error when I try to compile it:

Well, Arduino IDE 2.0 is much nicer to use with very little learning curve!
ESP 2.0.11 board defs are most likely mandatory but older ones may still work.
I would update all libraries and, then, I would copy the contents of the Lib directly to your libraries and overwrite all, as 'replace'. In that order.
["I typically download the zip from Git Hub and launch from the extracted files. Is that good enough? If I have that local file structure do I need any of the libraries installed? "] should be OK.

I typically download the zip from Git Hub and launch from the extracted files. Is that good enough? If I have that local file structure do I need any of the libraries installed? I'm just wondering if I might try a fresh IDE install with just the zip from LilyGO.

I would do a complete Arduino IDE Library update.
I am using the "Arduino_GFX_Library.h" straight from the LilyGO supplied GitHub repository.
LilyGO can be annoying by modifying standard libraries to work with their custom designs...without re-naming the LilyGO_Arduino_GFX_Library.h (e.g.)
So for my successful test I cloned the LilyGO repository for the T-RGB and ran the example from inside the examples folder.

I don't have a T-RGB to try but the GFX example compiled first try.
I using:
Arduino IDE 2.2.1
ESP 2.0.11
I used Github to down load (clone) the complete set of files.
All my libraries are current.
Hope that helps -Terry

//  Full circle 2.1 inches using CST820 touch screen
// #define USING_2_8_INC_GT911      1           
//  Full circle 2.8 inches using GT911 touch screen
// #define USING_2_1_INC_FT3267     1           
//  Half circle 2.1 inches use FT3267 touch screen

BTW When people are impressed that an old guy is into Arduino IDE, I compare it to the skill and complexity of building a ship in a bottle.
