| |
Linux has an recent option to define CROSS_COMPILE in menuconfig.
Typically, one of the options when building for another target is ('arm' is just an example):
# make ARCH=arm CROSS_COMPILE=arm-cc O=../build
If I omit CROSS_COMPILE and use the new way in .config: CONFIG_CROSS_COMPILE="arm-cc"
I got:
cc1: error: unrecognized command line option "-mlittle-endian" cc1: error: unrecognized command line option "-mabi=aapcs-linux" cc1: error: unrecognized command line option "-mno-thumb-interwork" /usr/src/linux/kernel/bounds.c:1: error: bad value (armv5t) for -march= switch /usr/src/linux/kernel/bounds.c:1: error: bad value (armv5t) for -mtune= switch make[2]: *** [kernel/bounds.s] Error 1 make[1]: *** [prepare0] Error 2 make: *** [sub-make] Error 2
Verbose output clearly says that I'm using the host compiler instead cross compiler. This patch fixed my problem:
