Error on enable support for SPI TFT displays

[GustavoRSSilva]

I am trying to enable support for SPI TFT displays.

Everything seems to work properly expect when I enable this option.

The error is:

https://loboris.eu/forum/showthread.php?tid=111 shows following, and it works for me.

After changing the configuration via menuconfig you should (almost always) clean the build first:

./BUILD clean

or to clean and build: ./BUILD clean all

or for faster build: ./BUILD -j4 clean all

I have the exact same problem. I tried ./BUILD clean: no success. milinatw: could you please indicate what options you chose in menuconfig. Might there be a dependency?

[patbeppo]

After deselecting all modules, build clean (without any -j) and selecting it again it worked.
