I have just tested with Arduino IDE 1.8.13 and ESP8266 source code, no this error. You may try update the ESP8266 source code and try again.

I install last update the ESP8266 source code, also i tried reinstall IDE and delete everything that relates to it , but still not working((( I dont know what to do.

Arduino_TFT.cpp:1010:1: error: a15 cannot be used in asm here is odd since it is not asm code. Wild guess it may have file corruption, you may try delete the C:\Users\User\Documents\Arduino\libraries\GFX_Library_for_Arduino folder and get the library again.

Hi, thank you for your good lib. Note that this message is an incompatible change in the newer ESP8266 compiler: https://www.reddit.com/r/esp8266/comments/ggapj8/new_compiler_breaks_programs_error_a15_cannot_be/
If you upgrade your esp8266 compiler, you will likely see the same error.

This makes the compilation problem go away, of course it also breaks what your code is trying to do:

But it confirms that pgm_read_byte broke in the newer ESP8266 compiler. Are you able to replace this with new code that doesn't conflict with the compiler?

Is it only related to certain OS? I have no this problem in MacOS and I
also use FastLED with no problems.

If you have the arduino environment, go to board manager, esp8266, and check your version.
I think it's broken with 2.6.x and 2.7.x but it works with 2.5.x and earlier. The bug I just linked, gives details.
If I downgrade to 2.5.2, it works, but the problem is that it won't work anymore for anyone installing new arduino.
If you do not have an ESP8266 chip, you can still select ESP8266 and try to compile (verify) to see the error

I am using Arduino 1.8.13 on MacOS and just run git pull origin master --recurse-submodule under ~/Documents/Arduino/hardware/esp8266com/esp8266.

Thank you for the details.
I think you are correct, the compiler on linux and MacOS may not be the same.
Do you have a directory called hardware/esp8266 (maybe packages/hardware/esp8266 )?
which version do you have in there? do you have package.json ?
Mine looks like this for an old version
sauron [mc]$ cat package.json

Thank you. It looks like you have access to a completely different compiler on MacOS. This is quite confusing.
@dos1axgod is using windows, I'm using linux, and we are both seeing the exact same problem.
The latest in library manager, gives:
{
"name": "framework-arduinoespressif8266",
"description": "Arduino Wiring-based Framework (ESP8266 Core)",
"url": "https://github.com/esp8266/Arduino",
"version": "2.7.4"
}
and it does not work.
But I see you have the git version, so I went to https://github.com/esp8266/Arduino , then went to
/home/merlin/.arduino15/packages/esp8266/hardware/esp8266 , git clone https://github.com/esp8266/Arduino and renamed it to 3.0.0
Sure enough, that one worked, so they fixed the incompatibility they added in 2.6. This is great news. Unfortunately it's not released yet, so you need to use git to get it. It works for me though @dos1axgod try it too, it should work for you.
@moononournation , now that it builds again on ESP8266, I see a few new warnings:

oooh, that's a good idea, you basically undo the change in the new ESP8266 compiler suite and restore the old define they used to have. Nicely done.
