I compiled it before with ESP32.
I tried to compile it again for ESP8266 but fail, I got this error

Can any one help me please to solve this problem,

Thanks on advance.
Best regards

I don't know why it gives you an error Recheck the installation of b4r and arduino sdk

 

[Adamdam]

Yes, Mr. XorAndOr ,
The problem with me due to the B4R compiler setting/configuration.
I need help to find my error and how to solve it.
