Coreutils impossible to compile and bash pipes

[AlfaOmega08]

My kernel is finally able to execute bash. Now I want to port coreutils using my cross-compiler.

When configuring the script exit with this error:

configure: error: could not determine how to read list of mounted file systems

Someone knows how to make it work?

The only problem I got with bash are pipes. If I execute e.g. "ls | grep ..", I receive a page fault.
Do I need some special syscall to handle pipes?

Well, assuming you are running this on your OS, it probably needs some syscalls you haven't implemented?

exec, and, what's it dup or something?, to get stdin/out to be linked. But really, it should be rather straigtforward to debug, right? Or have you just compiled bash without a clue what's in it?

"pipe" and "dup2" are what's required.

Ah, yes, I haven't got a copy of POSIX in my head :). Anyway, it seems to me the OP could do much more research himself.

I ran into the exact same problem while trying to cross compile GNU coreutils packages with newlib. I poked around the configure script a bit to no avail.

(Congrats on getting bash running, nice feeling isn't it?)
