I don't know? What did you do?
I do start makefile
I wrote and tested this only on Mac. Are you using Linux?
yes
same problem in macOS
I know its late but add -fno-pie to gcc compilation
May I know the code with -fno-pie added?
its --no-pie and not -fno-pie
Adding -fno-pie in gcc fix the problem to me
gcc -fno-pie -m32 -ffreestanding -c kernel.c -o kernel.o
