Porting dash with already made the executable.

[chrissacchi]

Hey, guys! I am making my own operating system, and I'm wondering: how I can run dash at startup? I have already ported dietlibc (from a CVS repo) and have successfully built my own cross-compiler.

"How can I run?"

It is a much to vague question.

I mean: How can I port dash shell so that it runs at startup in my new OS?

As with any software development cycle, split the objective into small pieces into:
- port dash
- runs
- at startup

port dash
There are articles on porting dash, which itself involve its own dependency and more works to do - further break them down

run an application
This can be further break down into (or depends on):
- process management
- VFS (so to load the executable)
- user mode (optional)
- kernel service / syscall / API
- etc


at startup
This is probably the easiest part, just define your logistic for boot sequence.
