You can reproduce using the following defconfig: BR2_arm=y BR2_cortex_m4=y BR2_TOOLCHAIN_EXTERNAL=y BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-cortex-m4-full-2017.11-rc1.tar.bz2" BR2_TOOLCHAIN_EXTERNAL_GCC_6=y BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_13=y BR2_TOOLCHAIN_EXTERNAL_LOCALE=y # BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set # BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_NPTL is not set BR2_TOOLCHAIN_EXTERNAL_CXX=y BR2_INIT_NONE=y # BR2_PACKAGE_BUSYBOX is not set BR2_PACKAGE_I2C_TOOLS=y # BR2_TARGET_ROOTFS_TAR is not set Could you look into this, and submit an updated version? It would be preferably to support building without shared library support, because i2c-tools are very basic, and potentially useful on noMMU systems. Thanks!
