How building and run

[ShadowASO]

I'm trying compiler and exec this OS without sucess. I can compiler but not run. This is my script.
#!/bin/bash

RAMSZ=$1
RAM=" -m $RAMSZ"

QEMU="qemu-system-x86_64 "

BOOT_BIN="kern/image"
RAMDISK_BIN="build/ramdisk"
FINAL_HD_IMAGE="build/hd-image"

if [[ $RAMSZ == "" ]]; then
RAM=" -m 128"
fi

echo "qemu: ram = $RAM"

Software emulation

qemu-system-x86_64 \

AMD-V or Intel VT

Use QEMUs multiboot capabilities to boot the kernel directly,

attach a PATA drive and simulate 8 CPUs

Required images: kernel, hdimage

HD=""
KERNEL=""
SMP=" "
APPEND="-monitor stdio -no-reboot "
HD="-drive format=raw,file=build/hd-image,media=disk"

#HD="-drive format=raw,file=build/hd-image,if=ide,media=disk"
KERNEL="-kernel build/hd-image"
SMP="-smp 2"
#APPEND="-append "use_debug_port=1 root=769 loglevel=0 vga=1 use_acpi=1""
#APPEND=" -monitor stdio"

QEMUFLAGS=" -no-reboot"
QEMUFLAGS+=" -boot d "
QEMUFLAGS+=" -net none"
QEMUFLAGS+=" $RAM "
QEMUFLAGS+=" -smp sockets=1,cores=4,threads=1 "
QEMUFLAGS+=" -serial stdio "
QEMUFLAGS+=" -drive format=raw,file=build/hd-image,media=disk"
#QEMUFLAGS+=" -drive format=raw,file=boot/bootsect.bin,media=disk"

#QEMUFLAGS+=" -hda kern/image"
#QEMUFLAGS+=" -cdrom $(iso)"
#QEMUFLAGS+=" -hda HDOS-Lab.img"

#"CMD="$QEMU $RAM $SMP $HD $KERNEL $APPEND"

CMD="$QEMU $QEMUFLAGS"

echo "Running " $CMD
#echo $QEMUFLAGS
eval $CMD

How run it?
