Very confusing. You want to use Pascal, C++ or both?

C++, although Pascal is easy to write, but I think Pascal couldn't call any Pascal's function

And a reason......
I don't have any servers.
So, it might be more and more harder build x86_64 elf on Windows

My hopes are a CLI, have a shell(hpsh-hyperon shell)

In that case you can find the C++ example kernel here, mykernel/cpp

What kind of servers are you talking about? There are no servers involved in this.

FreePascal can generate both ELF and PE on both Linux and Windows systems. For C++ you could use LLVM CLang, that can generate both ELF and PE on both Linux and Windows. Otherwise for GNU gcc you'll need a cross-compiler. Try MSYS2, it can install many different compilers for you, gcc cross-compilers included. Or use WSL.

Not so long ago it was a GUI. You can do both, GUI and a CLI, and it doesn't matter in which order you implement those. For a CLI, you probably want to implement a VT100 emulator first, then a shell. For GUI, see GUI first, and then when you have a windowing system, you can emulate VT100 in a window, and run the same shell in that.

Maybe you should start with the basics (that page explains the difference between GUI, CLI and shell), and it would worth reading the beginner mistakes too.

Agreed. Looks like the OP doesn't know what they want.

I have successfully used freebasic + fasm to build my os under windows
