[syslinux] how to compile syslinux-4.03

[Aaron Luo]

Hi,

Is anyone compiled a new pxelinux.0 with syslinux code 4.03?
right now, I got a error in compiling this version code,

objdump -h pxelinux.elf > pxelinux.sec
perl lstadjust.pl pxelinux.lsr pxelinux.sec pxelinux.lst
objcopy -O binary pxelinux.elf pxelinux.raw
../lzo/prepcore pxelinux.raw pxelinux.bin
../lzo/prepcore: pxelinux.raw: output too big (30197, max 0)
make[1]: *** [pxelinux.bin] Error 1
rm ldlinux.raw isolinux-debug.raw pxelinux.raw isolinux.raw ldlinux.o
pxelinux.o isolinux.o isolinux-debug.o
make[1]: Leaving directory `/root/syslinux-4.03/core'
make: *** [all] Error 2

I think the problem cause in this utility *prepcore*. 
can any one help me to resolve this problem?

thanks

Aaron
