In commit6136765b23("toolchain: generate check-headers program under $(BUILD_DIR)"), the check_kernel_headers_version function was simplified to not check the return value of the check-kernel-headers.sh script, assuming that "make" does bail out on the first failing command. However, check_kernel_headers_version when used in $(2)_CONFIGURE_CMDS from pkg-toolchain-external.mk, is called in a sequence of commands, where the return value of each command is not checked. Therefore, a failure of check-kernel-headers.sh no longer aborts the build. Since all other macros are using this principle of calling "exit 1", we revert back to the same for check_kernel_headers_version, as it was done prior to6136765b23.

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.
