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.
