A compiler that can build linux.
That level of quality should be sufficient.
Do you know any low quality programmers that write C compilers in rust THAT CAN BUILD LINUX?
No you don't. They do not exist.

Also, the booting part, as stated some times, is discutable.
Huh. Interesting. Like the other guy pointed out, compiler classes often get students to write toy C compilers. I think a lot of students don't understand the meaning of the word "toy". I think this thread is FULL of people like that.
Lots of segfaults, too.
So, things you don't think I or my coursemates could do include writing a C compiler that builds a Linux kernel.
What else do you think we couldn't do? I ask because there are various projects I'll probably get to at some point.
Things on that list include (a) writing an OS microkernel and some of the other components of an OS. Don't know how far I'll take it, but certainly a working microkernel for one machine, if I have time I'll build most of the stack up to a window manager. (b) implementing an LLM training and inference stack. I don't know how close to the metal I'd go, I've done some low level CUDA a long time ago when it was very new and low-level, depends on time. I'll probably start the LLM stuff pretty soon as I'm keen to learn.
Are these also impossible? What other things would you add to the impossible list?
Amiga OS is basically a microkernel and that was built 40 years ago. There are also many other examples, like Minix. Do I think most people could build a full microkernel based mini Unix? No. But they could get “something” working that would qualify as an OS.
On the other hand, there are not many C compilers that build Linux. There are many implementations of C compilers, however. The goal of “build Linux” is much more specific.
So what other projects are impossible? That was my question.
Doing a real compiler to be used by humans is difficult. Doing a compiler that “gets the thing done” is a different thing.
I think you might be thinking of C++
I also should’ve qualified my message with “in 2 weeks”, or even “in 2 months.” Given more time it’s obviously possible for more people.
You can give a developer the GCC test suite and have them build the compiler backwards, which is how this was done. They literally brute forced it, most developers can brute force. It also literally uses GCC in the background... Maybe try reading the article.
