compiling the Hurd from an installed glibc?

[Marcus Brinkmann]

Hi,

in trying out the new interfaces, I noticed that it is very inconvenient to
do so in a native environment.  The problem is two-fold:

I need to compile glibc with the new interfaces, so I have to install them
into my system.  It would be nice to have a way to tell configure and the
Makefiles to look for the interfaces in a different install prefix.

I need to compile the Hurd with the new glibc.  However, installing glibc
would leave me with a broken system, so I need to install it in a staging
area and compile the Hurd with the version there.  However, I did not find
an easy way to set up gcc and everything to make it link with a glibc
different with the /lib one.  My experiments included various combinations
of -B, -nostdinc, -L and -I (with the problem being -nostdlib, because that
removes the startup files etc).  It would be good to have a way to tell
configure of the Hurd to set up an environment so I can use a different
glibc install than /.

OTOH, the right fix for all of this is probably to not change the interfaces
in a non-backward compatible way :)

Thanks,
Marcus
