The kernel headers must be at least as old as the oldest kernel you intend to run on your target. If you use Buildroot to build a kernel, then you can use the sources from that kernel as source for the headers. If you choose a custom version of the kernel headers, or choose to use the same sources as the kernel, you'll have to select (below) the series of that kernel, so that Buildroot can show or hide packages that have strong requirements on the kernel headers. config BR2_KERNEL_HEADERS_AS_KERNEL bool "Same as kernel being built" depends on BR2_LINUX_KERNEL select BR2_KERNEL_HEADERS_LATEST if BR2_LINUX_KERNEL_LATEST_VERSION config BR2_KERNEL_HEADERS_4_4 bool "Linux 4.4.x kernel headers" depends on !BR2_riscv depends on !BR2_csky select BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_4 config BR2_KERNEL_HEADERS_4_9 bool "Linux 4.9.x kernel headers" depends on !BR2_riscv depends on !BR2_csky select BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_9 config BR2_KERNEL_HEADERS_4_14 bool "Linux 4.14.x kernel headers" depends on !BR2_riscv depends on !BR2_csky select BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_14 config BR2_KERNEL_HEADERS_4_19 bool "Linux 4.19.x kernel headers" depends on !BR2_csky select BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_19 config BR2_KERNEL_HEADERS_5_4 bool "Linux 5.4.x kernel headers" select BR2_TOOLCHAIN_HEADERS_AT_LEAST_5_4 config BR2_KERNEL_HEADERS_5_9 bool "Linux 5.9.x kernel headers" select BR2_TOOLCHAIN_HEADERS_AT_LEAST_5_9 config BR2_KERNEL_HEADERS_5_10 bool "Linux 5.10.x kernel headers" select BR2_TOOLCHAIN_HEADERS_AT_LEAST_5_10 select BR2_KERNEL_HEADERS_LATEST config BR2_KERNEL_HEADERS_VERSION bool "Manually specified Linux version" help This option allows you to use a specific official version from kernel.org, like 2.6.x, 2.6.x.y, 3.x.y, ...
