MBX kernel compile error

Hi,

I tried to compile linux kernel for MBX board on
i686-pc-linux. The package I used to built my
cross-compiler is:

    binutils-2.10
    glibc-2.1.3
    gcc-2.95

The kernel package I used is

    linux-2.2.17

I passed make xconfig, make dep, make clean, but got
the following error at make zImage:

powerpc-linux-gcc -D__KERNEL__
-I/home/compiler/sources/linux/include -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer
-fno-strict-aliasing -D__powerpc__ -fsigned-char
-msoft-float -pipe -fno-builtin -ffixed-r2
-Wno-uninitialized -mmultiple -mstring -mcpu=860
-D__ASSEMBLY__ -c head.S -o head.o
head.S: Assembler messages:
head.S:1829: Error: unsupported relocation type
make[1]: *** [head.o] Error 1
make[1]: Leaving directory
`/home/compiler/sources/linux/arch/ppc/kernel'
make: *** [_dir_arch/ppc/kernel] Error 2

Could anyone give me any idea about where I was wrong?

Thank you.
Yiran.

I've built for MBX with almost the same, only binutils 2.9.5 instead
of 2.10.

    linux-2.2.17

Looking at
  http://lxr.linux.no/source/arch/ppc/kernel/head.S
the problem is apparent:

  255 #ifndef CONFIG_8xx
  256         bl      prom_init
  257         .globl  __secondary_start
  258 __secondary_start:
  ...

  1293 #ifndef CONFIG_8xx
  ..
  1822 #else  /* CONFIG_8xx */
  1823         .globl  giveup_fpu
  1824 giveup_fpu:
  1825         blr
  1826 #endif /* CONFIG_8xx */
  1827
  1828 mmu_off:
  1829         addi    r4, r3, __secondary_start - _start
  1830         mfmsr   r3

__secondary_start is not defined for CONFIG_8xx.  It looks like
head.S changed a bit since 2.2.14, and I wouldn't know which way to go
about fixing it, but I might suggest either backing down to 2.2.14 or
jumping to 2.4.0-test2.

The latest Monta Vista CDK (1.2) appears to include both, and last I
tried their stuff worked quite well with little headaches - I'd recommend
giving it a try,

Thank you.

Hi,

What does LIST_HEAD do in drivers/pci/pci.c ?

     LIST_HEAD(pci_root_buses);
     LIST_HEAD(pci_devices);

Thanks,

Try this:

   demo% grep -C LIST_HEAD /usr/src/linux/*.h

Ooops, I meant:

    demo% grep -C LIST_HEAD /usr/include/linux/*.h

which should be the same as:

    demo% grep -C LIST_HEAD /usr/src/linux/include/linux/*.h

Hi,

Anybody knows where the function "pci_read_config_byte(..)" is defined ?

Try looking in drivers/pci/pci.c This is where the code resides. It
is also where the symbol is exported.

Search for 'PCI_OP' in drivers/pci.c. Also, there are machine-specific
routines defined in arch/ppc/*pci*.

Do yourself a favour and grab "cscope" from sourceforge at:
    http://sourceforge.net/projects/cscope/

I find it extremely handy for navigating the Linux kernel source tree.
