uCLinux移植到S3C44b0X

(我用的是ubuntu)
我这里有两个问题：
我按照顺序执行:make menuconfig
make dep
make lib_only
make user_only
make romfs
make image
make
的时候出现以下两个问题
问题（1）：就是在make image的时候出现下面的错误：
/usr/local/bin/arm-elf-ld -r -o /home/zcz/linux_workspace/uClinux-dist/linux-2.4.x/romfs.o \
-b binary /home/zcz/linux_workspace/uClinux-dist/images/romfs.img
/usr/local/bin/arm-elf-objcopy -O binary -R .note -R .comment \
-S /home/zcz/linux_workspace/uClinux-dist/linux-2.4.x/linux /home/zcz/linux_workspace/uClinux-dist/images/image.ram
/usr/local/bin/arm-elf-objcopy: /home/zcz/linux_workspace/uClinux-dist/linux-2.4.x/linux: No such file or directory
make[1]: *** [image] Error 1
make[1]: Leaving directory `/home/zcz/linux_workspace/uClinux-dist/vendors/Samsung/44B0'
make: *** [image] Error 2

问题（2）就是在make 的时候出现下面错误：
drivers/char/char.o(.text.init+0xe0): In function `write_mem':
/home/zcz/linux_workspace/uClinux-dist/linux-2.4.x/drivers/char/mem.c:120: undefined reference to `s3c44b0x_console_init'
