The external toolchain configure step calls the check_kernel_headers_version make function to compare the kernel headers version declared in the configuration with the actual kernel headers of the toolchain. This function takes 4 arguments, but due to a missing comma what should be the first two arguments are both passed into the first argument. Due to this, when check_kernel_headers_version does: if ! support/scripts/check-kernel-headers.sh $(1) $(2) $(3) \ $(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \ Then: $(1) contains "$(BUILD_DIR) $$(call toolchain_find_sysroot,$$(TOOLCHAIN_EXTERNAL_CC))" $(2) contains "$$(call qstrip,$$(BR2_TOOLCHAIN_HEADERS_AT_LEAST))" $(3) contains "$$(if $$(BR2_TOOLCHAIN_EXTERNAL_CUSTOM),loose,strict))" So from the point of view of check-kernel-headers.sh, it already has four arguments, and therefore the additional argument passed by: $(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \ is ignored, defeating the $(BR2_TOOLCHAIN_HEADERS_LATEST) test. The practical consequence is that a toolchain that has 5.4 kernel headers but declared as using 5.3 kernel headers does not abort the build, because the check is considered "loose" while it should be "strict".

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
