Newbie on embedded linux on PPC: error: cannot find boot.o

Newbie on embedded linux on PPC: error: cannot find boot.o

[Thomas Gerlach]

hi folks,


my name is thomas trying to make embedded linux run on a powerpc, but we've got special boards here, although we use a xilinx virtex4 fpga...

as you said in the nabble-thread (see subject), i set up edk9.1 software platform settings und ran libgen to get the xparameters* files. i copied those bsp files into the kernel tree (i use your kernel linux-2.6-virtex from git.secretlabs.ca/git). after configuring the kernel settigs, i try

$ make ARCH=ppc CROSS_COMPILE=powerpc-eabi-

what i get is the following output:

>   CHK     include/linux/version.h
>   CHK     include/linux/utsrelease.h
>   CALL    scripts/checksyscalls.sh
>   CHK     include/linux/compile.h
>   LD      init/mounts.o
> powerpc-eabi-ld: cannot find boot.o
> make[1]: *** [init/mounts.o] Error 1
> make: *** [init] Error 2

so, i searched for boot.o (it exists) and even copied it into several dirs of the linux kernel tree (where i thought i would make sense), but the problem still remains.

googling results in

and this, too, doesn't take me further in solving the problem.

i hope you can help me.

many thanks in advance,

kind regards

You should be using a Linux cross compiler, not powerpc-eabi-.  The
Xilinx cross compiler will not work to compile Linux kernels.

You can build yourself a cross compiler using 'crosstool':
http://www.kegel.org/crosstool.

Alternately, you can download ELDK:

Hi Thomas,

Xilinx is building the tools in the EDK to work with VxWorks and for Standalone systems. In order to compile a Linux kernel you need to get a toolchain from one of the Third Party vendors, such as MontaVista. They have the correct linker scripts for building a kernel.

Cheers,
   Wolfgang

hi,
thank you much for this hint. this was the last thing i thought of... ;)

so long, keep on cross-compiling! :)

hi,
thank you much for this hint, i'll try it. this was the last thing i 
thought of... ;)

kepp on cross-compiling, :)

You can also build a ppc405 toolchain using Crosstool, and it works
fine..
