Hi All, I'm having trouble compiling my kernel using a 32-bit toolchain (for ARM) on a 64-bit host (Ubuntu 14.10). The kernel version is 3.14.17. I understand that 32-bit binaries require "ia32-libs" (or equivalent) for compiling on 64-bit hosts. I installed the required packages (lib32z1 lib32ncurses5 lib32bz2-1.0 for Ubuntu 14.10), but still keep getting errors: $ make CROSS_COMPILE=arm-none-linux-gnueabi- all Makefile:616: Cannot use CONFIG_CC_STACKPROTECTOR_REGULAR: -fstack-protector not supported by compiler make: arm-none-linux-gnueabi-gcc: Command not found CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date. CC kernel/bounds.s /bin/sh: 1: arm-none-linux-gnueabi-gcc: not found make[1]: *** [kernel/bounds.s] Error 127 make: *** [prepare0] Error 2 I've ensured that the PATH to the toolchain binaries is correct. If I try to export CROSS_COMPILE to my environment, then too I get an error (although it's for a different reason): $ make all Makefile:616: Cannot use CONFIG_CC_STACKPROTECTOR_REGULAR: -fstack-protector not supported by compiler CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date. CC kernel/bounds.s gcc: error: unrecognized argument in option ‘-mabi=aapcs-linux’ gcc: note: valid arguments to ‘-mabi=’ are: ms sysv gcc: error: unrecognized command line option ‘-mlittle-endian’ gcc: error: unrecognized command line option ‘-mapcs’ gcc: error: unrecognized command line option ‘-mno-sched-prolog’ gcc: error: unrecognized command line option ‘-mno-thumb-interwork’ gcc: error: unrecognized command line option ‘-mfpu=vfp’ make[1]: *** [kernel/bounds.s] Error 1 make: *** [prepare0] Error 2 It looks like make is starting a new shell which does not have either PATH (1st case) or CROSS_COMPILE (2nd case) set. Any hints on how to get make to use the toolchain?
