error in building boot image Sculpt OS

Good Afternoon

I am new to Sculpt OS and I was working on building genode from source code and then later on building boot image (sculpt OS). I faced an issue while working on the boot image when I run the following line :

make -C build/x86_64 run/sculpt KERNEL=nova BOARD=pc

Error presented with and without debug in the image shown below (image 1 and 2) .

I also noticed the error changed if I revert the changes I made in build.conf for building genode from source code (image 3) asboth the process required modifying the same file.

This was the official document like via which I tried to build boot image : https://genode.org/documentation/articles/sculpt-22-04#Building_the_boot_ima...

How should I resolve this issue ?

Thanks Vasvi
