Problem at the building for ESP32S3N16R8

Hi Wolle!
I tried to make a actual build (Feb,2nd) for ILI9488 display with TP9488 and build failed:

The problem is in SPI call. Could you help?

Thank you, that was a copying error on my part.
Instead of
extern TFT_SPI tft(spiBus, TFT_CS);
it should correctly read
extern TFT_SPI tft;.

Hi Wolle!
Thank you for your response. I made a correction. After this the build stopped at function.hpp in line 6:
I changed it to:
extern TFT_SPI tft;
and made the build again. Here is the result:

Successfully created ESP32S3 image.

What do you propose to do?

[schreibfaul1]

It is unfortunate that it did not work.
I have completely removed the "external..." part.
How does it look now?

[JozefKc]

Works again. Thank you.
