[HELP] Compile error with GCC 4.7

---

Hi everybody.

I use Linaro toolchain 2012.05 GCC 4.7 on my Archlinux x86_64 and when I compile Nexus S stock kernel, I have some errors like these:

[matt@ArchLinux samsung]$ make
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: «include/generated/mach-types.h» è aggiornato.
  CC      kernel/bounds.s
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 argument in option ‘-mabi=aapcs-linux’
gcc: note: valid arguments to ‘-mabi=’ are: ms sysv
gcc: error: unrecognized command line option ‘-mno-thumb-interwork’
make[1]: *** [kernel/bounds.s] Errore 1
make: *** [prepare0] Errore 2

With GCC 4.6 I have another errors. I want to use GCC 4.7 like Thalamus.

Can you help me?

PS:

export ARCH=arm
export CROSS_COMPILE=
export PATH=$PATH:~/android-toolchain-eabi/arm-eabi/bin/

Q&A Section would be the right place for this.

Thank you! Now I have some errors.

Can I risolve it?

Those are warnings, read up on building kernels more.

I use this guide: http://source.android.com/source/building-kernels.html

You'll really get more help if you post this in the correct section. That's what the Q&A section is for - Questions and Answers.

Try to use the bfd linker, which is also provided at the linaro prebuild toolchain package. For details look at:
