[LinuxBIOS] Problem on Compilation

I have change my parameter in
LinuxBiosV2/targets/advantech/pcm-5823/Config.lb

target pcm-5823
mainboard advantech/pcm-5823

option DEFAULT_CONSOLE_LOGLEVEL=8
option MAXIMUM_CONSOLE_LOGLEVEL=8
option CONFIG_COMPRESSED_PAYLOAD_NRV2B=1

option ROM_SIZE=(256*1024)-(64*1024)-(32*1024)
#option FALLBACK_SIZE = ROM_SIZE

romimage "normal"
        option USE_FALLBACK_IMAGE=0
        option LINUXBIOS_EXTRA_VERSION=".0Normal"
        option ROM_IMAGE_SIZE=64*1024
        payload ../../../../etherboot-5.2.6/src/bin/rtl8139.elf
end

romimage "fallback"
        option USE_FALLBACK_IMAGE=1
        option LINUXBIOS_EXTRA_VERSION=".0Fallback"
        option ROM_IMAGE_SIZE=64*1024
        payload ../../../../etherboot-5.2.6/src/bin/rtl8139.elf
end

buildrom ./linuxbios.rom ROM_SIZE "fallback" "normal"

Adn I have the same error :

LOVER_IMAGE='0' -Os -nostdinc -nostdlib -fno-builtin  -Wall -o
rom_stream.o /home/ccases/LinuxBIOSv2/src/stream/rom_stream.c

I don't now why :(

If anyone has a solution, thank's by advance for your help
