Re: warning while running [libc]/configure

[Alfred M. Szmidt]

   It prints warning message:
   configure: WARNING: --prefix= (empty) is requed for GNU/Hurd to work
   normaly.

   I wish to install libc to the root. So I try
   $ ../configure --prefix=/
   Warning message printed again, --prefix="/" follow to same results.

   Why setting --prefix does not avoid warning message?

Because of the following:

,----[ (standards)Directory Variables ]
| When building the complete GNU system, the prefix will be empty and
| `/usr' will be a symbolic link to `/'.
`----

So setting --prefix to / is wrong, and it should be empty, as the
warning correctly notes.
