Kernel build error with IMX53 QSB

[Swamy]

Hi,

I am trying to build the kernel module, I am using linux-2.6.35.3 headers for compilation. I am getting following error. Request you to please guide,

cc1: error: unrecognized command line option "-mlittle-endian"
cc1: error: unrecognized command line option "-mapcs"
cc1: error: unrecognized command line option "-mno-sched-prolog"
cc1: error: unrecognized command line option "-mabi=apcs-gnu"


Regards,
Swamy

Here is how you build a kernel without the sources - just the headers:

The procedure can be easily adapted to the mx5 kernel.

Did you configure your source code? 

I don´t know how to build a module without the kernel source code, although it looks like it´s a configuration missing error...

Hi,

Thanks for your reply,

I tried your command, I am getting this error (attached file). Please suggest.

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.

Did you set up your cross-compilation correctly?

You need to set the CROSS_COMPILE=[toolchain prefix] and ARCH=arm when you compile, e.g.

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -j6

Also, your cross-compiler needs to be in the PATH.
