Hello all
I tried to port linux 2.6.11-mipscvs-20050313 on MIPS 4KEC processor.
But I faced with some problems.
1. I have question regarding toolchain, I use toolchain which came from
uclibc buildroot
application. Gcc version is 3.4.2, is it ok?
2. I tried to use sde-lite 5.03 toolchain but this toolchain (sde-gcc)
failed to build kernel.
Please any comments regarding this issue?
3. I tried to remove optimization from kernel:
ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE
CFLAGS += -Os
else
#CFLAGS += -O2
endif
but kernel failed to compile with next messages:
init/built-in.o(.init.text+0x216c): In function
`identify_ramdisk_image':
init/do_mounts_rd.c:92: undefined reference to `ntohl'
kernel/built-in.o(.text+0xf6f4): In function `put_files_struct':
include/asm/system.h:270: undefined reference to
`__xchg_u64_unsupported_on_32bit_kernels'

kernel/built-in.o(.text+0x13278):include/asm/system.h:273: undefined
reference to `__xchg_called_with_bad_pointer'
....
I tried with googling but it seems that nobody faced similar problem? Is it
possible to buidl kernel without optimization?
Best regards Mile
