Error while building LibreELEC for Khadas vim

I have tried to build Libre ELEC up to the step “make -j8 CROSS_COMPILE=aarch64-linux-gnu-” under build U-boot. The following screen shot is showing the error while executing the last step. Please find the attachment and do the needful to overcome the error

i found the solution … thanks for no replays and comments.
solution is “sudo apt-get install gcc-aarch64-linux-gnu”.Then try again.
This is becz aarch64-linux-gnu-gcc is not installed.

please help me … i got stuck in Build Initramfs and RAM Disk stage. While typing the below command "make -C initrd " .
error shown is

cinesoft@Cinesoft-Electronics-dept:~/project/khadas/ubuntu/u-boot/linux$ make -C initrd
make: Entering directory /home/cinesoft/project/khadas/ubuntu/u-boot/linux/initrd' find . ! -path "./.git*" \ ! -path "./" \ ! -path "./Makefile" \ | cpio -H newc -ov | gzip > ../images/initrd.img /bin/sh: 4: cannot create ../images/initrd.img: Directory nonexistent . ./etc ./etc/fstab ./etc/mtab make: *** [all] Error 2 make: Leaving directory/home/cinesoft/project/khadas/ubuntu/u-boot/linux/initrd’

Did you want to build the LibreELEC? But I saw the path information from you was about Ubuntu.
About how to create the Initrd and ramdisk,you can refer to the post
