ERROR: rm: cannot remove 'kernel.img': No such file or directory - makefile

Question

I've been trying to get my Raspberry Pi 4 OS (not Linux or anything, I'm making an OS from scratch) to work.
The Makefile has this error when I use the command "make":
rm -rf objects
rm -rf SuperPiOS.elf
rm SuperPiOS.img
rm: cannot remove 'SuperPiOS.img': No such file or directory
make: *** [Makefile:110: clean] Error 1
I can't figure out why it wouldn't work though.
Here's the Makefile:

Answer 1

You have two problems. The most obvious one is that this command:
rm SuperPiOS.img
is failing because that's how the rm program is defined: if the file you ask it to delete doesn't exist then rm will fail. If you don't want that to happen, add the -f option:
rm -f SuperPiOS.img
Now if the file doesn't exist, rm will silently succeed. You can examine the man pages for the rm program.
However, the higher level question you are probably asking is, why when I run make is it running the clean rule?
That's because make, if you don't specify what to build on the command line, always builds the first explicit target. In this makefile the first explicit target you defined is clean, so that's what's built. This is almost certainly not what you want. You should figure out what target you want to build when you run make with no arguments and put the rule for that target as the first explicit target in your makefile.
Other than this rule it normally doesn't matter much what order rules come in (if you have multiple pattern rules that could all build the same target, for example multiple pattern rules to build %.o, then order can matter there).
