Help!Kernel compile problem!!!!!!

[superlau]

i was compile the kernel-source from sourceforge,but i got a error when i type
make zImage
in the kernel source directory!!!!
the result message:

my system is Gentoo 2005.1,and my host compiler's configure is

but i can build lot of any userspace program,any the flashkit kernel module,and run perfect!!!
any body tell me why?

As I know You can compile the kernel just only using the crosstool provide by Montavista.

Hi All,

Sorry for double posting!!!

I was able to generate a Toolchain!! Hello World works on Phone..

Was wondering whether anybody would shared with a copy of Kernel config file .config so that I can try compiling the kernel modules for my A780..

Thanks

See the README file (E680\ README.txt) in the tar you downloaded. The .config used for the A780 can be generated by the appropriate make command.

However, with the normal toolchain you'll be able to 'make modules' but not 'make zImage'. It fails on one assembly file that uses some unknown instructions. Other than that, the kernel compiles fine, but its useless without a working scheduler.

[alebm]

Maybe some wmmx instructions? hehe

[mack]

Yeah, but do you know how to build a toolchain that supports WMMX ?
Is there a public release of gcc that supports it ?

[evaldas]

try google, there are wmmx extensions in gcc 3.4 but i'm not sure if you'll be able to compile kernel.

U can get the pre .config in kernel direction in which linux-2.4.17/arch/arm/def-configs/ezx-780, What u need do is:
1 cd /usr/src/linux-2.4.17/
2 cp arch/arm/def-configs/ezx-780 .config
3 make oldconfig
4 make modules
Then u get the modules, And u can modify .config before u make oldconfig to create ur own modules.

you need to add an

#include <asm/proc/ptrace.h>

to the top of arch/arm/kernel/wmmx.S

and it will compile like a charm.
