Some toolchain can't be used by Buildroot due to sysroot location issue, so the $(ARCH)-linux-gnu-gcc -print-file-name=libc.a command return only "libc.a" This lead to an error during the header check version helper, so these toolchains can't be imported into Buildroot. cc1: fatal error: $PWD/libc.a/usr/include/linux/version.h: No such file or directory compilation terminated. support/scripts/check-kernel-headers.sh: line 38: /tmp/check-headers.4V5PPF: Permission denied This issue happen with the first linaro 2015.11 [1] release and CodeSourcery standard edition [2]. Here is the sysroot directory tree for linaro 2015.11: $ ls libc/arm-linux-gnueabihf etc lib sbin usr var Here is the sysroot directory tree for CodeSourcery standard: $ ls libc/sgxx-glibc etc lib lib64 sbin usr var Add a check to error out with an explicit error message The check don't use toolchain_find_libc_a function directly since "realpath -f" is used internally and return an absolute path.

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
