Description Harald Kubota 2006-09-01 07:37:22 UTC

crossdev for sh4-gentoo-linux-uclibc does not compile linux-headers-2.6.17 due to 2 bugs:
-m4-nofpu is not understood by gcc (4.1.1) as there's no multilib support for non-FPU systems compiled, and a header file defines something which is not used with something which is not defined.

The fix is simple if you always have an FPU (I do):
arch/sh/Makefile:
harald@play1$ diff Makefile.orig Makefile
42c42
<       $(call cc-option,-mno-implicit-fp,-m4-nofpu)
---
>       $(call cc-option,-mno-implicit-fp)

and include/asm-sh/page.h: change FPN_START to PFN_START as this:

#define ARCH_PFN_OFFSET             (FPN_START)

is likely a typo in the kernel headers. Then it's a problem of linux-2.6.17 and should be fixed there.

I'm using crossdev-0.9.16, gcc-4.1.1, uclibc-0.9.28.
