I think it has something to do with building limine? The only thing I can make from looking it up is the -no-pie -fno-pie and -fno-pic might help but the command the compiles limine excludes those commands
from limine-c-template.

Try replacing the -fno-pic flag with -fno-PIC; should that fail, you will either need to use a cross compiler (for x86_64-elf target) or you can use WSL if you're on Windows 10/11.

Alright, I followed the cross compiler instructions linked on the README and I get this output

I have a few more things I'm going to try.

Okay the other thing i was going to try was to compile limine with just CC and then compile the kernel with the cross compiler

Maybe I followed the instructions too closely. I was compiling for i686 elf. I will try again with x86_64-elf as the target

Okay. after redoing everything to compile for x86_64,

I can try again with WSL but i feel like this should work. what version of GCC do you use?

Ah, my bad. It says it doesn't recognize the option -z

Because you also need to pass LD=$TARGET-ld

Thank you. Maybe it should be noted that CC with Cygwin will not work (I assume because it's trying to build a windows executable, which is why the -z command is not present). Other than that most of this thread is just me demonstrating my incompetence on unix systems
