Hello everyone! I'm just getting started with OS dev. So far, I've had success with assembly only code (babysteps), but when I attempt a mixed language kernel (barebones C), I have problems. The compiling works fine, and generates good .o files, but when I try to link with it outputs Apparently ld can't access loader.o properly. I'm pretty sure what I typed into the command prompt is wrong, because Barebones didn't mention anything about the link command. Any suggestions?

I would be glad to update the tutorial once I get this figured out to prevent further confusion.

Thanks in advance!

the linker is looking for the entrypoint and isnt finding it in the C file. It shouldnt be an issue though overall. You will notice that if you included an assembly file with the label 'start' in the linker setup, it will go away.

I had that same issue. I looks really wierd. Replace "_loader" with "_main" in the link file ENTRY statement, and the error will go away and everything will still work fine. (as long as you link the loader.o first, I think)
