Hi,

I ran the command "./make.cross ARCH=arm arch/arm/" on my 64 bit x86
machine but got the following error:

scripts/Kbuild.include:113: *** Recursive variable `CC_OPTION_CFLAGS'
references itself (eventually).  Stop.
make: *** [arch/arm/] Error 2

I commented out the line "CC_OPTION_CFLAGS = $(filter-out
$(GCC_PLUGINS_CFLAGS),$(KBUILD_CFLAGS))" in the scripts/Kbuild.include
file and the driver compiled.

Is this the only solution to make the compilation work? What is this
line signifying?

Thanks,
Bhumika

I don't know what "make.cross" is supposed to do, but if it's invoking
the kernel build like this:

make CROSS_COMPILE=... ARCH=arm arch/arm/

then that is wrong - although we support building subdirectories using
that notation, that does not apply to arch/<$ARCH>/ subdirectories.  The
makefile in there is designed to be included into the kernel's top level
makefile, and is not a stand-alone makefile in the same way as (eg)
fs/Makefile, fs/ext4/Makefile or arch/arm/kernel/Makefile.
