Buildroot failed because of fbtft

[notro]

fbtft doesn't use struct timespec in 5.17, it uses ktime_t so I don't know how you can get the same compile error: https://elixir.bootlin.com/linux/v5.17/source/drivers/staging/fbtft/fbtft.h#L228

[notro]

Are you enabling this option on a >=4.0 kernel?

config BR2_LINUX_KERNEL_EXT_FBTFT
	bool "FB TFT drivers"
	select BR2_PACKAGE_FBTFT
	help
	  Linux Framebuffer drivers for small TFT LCD display modules,
	  e.g. Adafruit PiTFT displays for Raspberry Pi (this extra
	  package is only needed for linux kernels until v3.19, since
	  v4.0 the drivers are included in the staging area).

If so that's your problem.

Hello @notro . thanks for the answer.
Yes, that is enabled

[notro]

Unless you use an old kernel you need to disable that.

[OmidID]

I using 5.17 . Actually, I tried both, disabled and enabled. the result will be the same :(
Is there any flag or something that I must set to the gcc?
Currently, I using gcc 11.

YOU RIGHT!!!
I confused. How did I end up with this problem! :D
Maybe something is wrong with the Buildroot.
Do you have any idea what can check?

[notro]

If you disable the config option but doesn't clean the builddir, the driver stays around and you keep getting the error. The buildroot dependency system doesn't detect things like this.

I did clean before each make run. each time I waited for 1-2 hours.
