Hello, I have problem when compiling linux kernel for S3C2440 SoC, everytime the compiling failed with the following message,

Code:

  GEN     /tmp/kbuild/Makefile
scripts/kconfig/conf -s arch/arm/Kconfig
drivers/net/fec_mpc52xx/Kconfig:7:warning: 'select' used by config symbol 'FEC_MPC52xx' refer to undefined symbol 'PPC_BESTCOMM'

common-smdk.c:(.init.text+0xb98): undefined reference to `s3c2410_sysclass'
make[1]: *** [.tmp_vmlinux1] Error 1

And I have read some of the related code, doesn't find any clue. I am new to embedded linux, can anyboday give me some suggestion ? The toolchain used to compile it is arm-linux-gcc 4.0.0 (comes from ELDK4.1 for ARM).

Just googling for your symbol, it apparently causes some people issues if void. I'm no expert here btw.

http://www.fluff.org/ben/linux-26/26...0-ifdefs.patch

How do I phrase this neatly? Competitor sites also have references to it.

Thank you. I apply the patch, still cannot compiling the kernel.

But I find if I choose to include support for smdk2410 besides smdk2440, then I can compiling the kernel successfully without error and get a zImage.

What I want is a zImage for smdk2440 but not smdk2410. I don't know why should I include smdk2410 in kernel config ? I havn't tried to run the kernel been build in real hardware. I will try it later.
