U-boot crosscompile OSX failed

Hi all,

I'm trying to build u-boot release 2.0.8 on OSX, using this manual:
https://tinkerboarding.co.uk/wiki/index.php/Software#U-boot

make CROSS_COMPILE=arm-linux-gnueabihf- O=miniarm-rk3288 tinker-rk3288_defconfig all

HOSTCC scripts/basic/fixdep
GEN ./Makefile
HOSTCC scripts/kconfig/conf.o

make[2]: *** [tinker-rk3288_defconfig] Error 2
make[1]: *** [__build_one_by_one] Error 2
make: *** [sub-make] Error 2

flex 2.6.4 is installed.

uname -a output:
16.7.0 Darwin Kernel Version 16.7.0: Wed Oct 4 00:17:00 PDT 2017; root:xnu-3789.71.6~1/RELEASE_X86_64 x86_64

Any ideas? I see in the Makefile a sort of OSX support, so it should work in general.

Thanks.

I am not sure if it can build from OSX directly. Our experience is that we need to install a virtual machine which runs Ubuntu on it. and use the Ubuntu environment to build the u-boot/kernel.
