This problem is resolved, now i can compile my program, but as the
result i receive:

/home/xpurogo/ecos/gnutools/arm-eabi/bin/../lib/gcc/arm-eabi/4.3.2/../../../../arm-eabi/bin/ld:
address 0x40004b7c of a.out section .bss is not within region ram. I
know that this is common question, but is there any common answer for
that? :)

My linker script looks like that:

MEMORY
{
    ram : ORIGIN = 0x40000000, LENGTH = 16k
    rom : ORIGIN = 0x00000000, LENGTH = 256k
}

These are available memory sizes for my system. I'm using kernel
konfiguration, which seems to be too big to handle in memory? I've
tried use minimal configuration but i've got more stragne errors
trying to compile my program. Is it possible to disable some options
in kernel configuration to handle that?
