Problem with shared libraries in HHL with initrd

[Kári Davíðsson]

You need to mimic the installation in you cross development environment,
e.g.
if your cross development libraries are in /usr/cross/lib on your host
you should put
them at the same place on your ramdisk.

In addition you nee the linker in /lib, i.e. something like the
following
-rwxr-xr-x   1 root     0          182887 Apr 16  2000 ld-2.1.3.so
lrwxrwxrwx   1 root     0              11 Aug 23  2000 ld.so.1 ->
ld-2.1.3.so
The linker is in /usr/cross/lib on your cross development host.

There is a lot of stuff in /usr/cross/lib. Some you need some you don't.
I managed to cut the libs down to the following, and you might even
strip it more.

-rwxr-xr-x   1 root     0            3652 Aug 17  2000

Subject: Problem with shared libraries in HHL with initrd



Hi

I am using Hard Hat Linux 1.2 with a custom MPC823 board and I am trying
to
create a minimal initial ram disk, so the board can boot without having
an
NFS root file system.  I am having a problem because shared libraries
are
not being found.  For example init reports:

  init: error in loading shared libraries: libc.so.6: cannot open shared
object file: No such file or directory

My minimal file system has the following directories: /bin, /dev and
/lib .
I put the shared libs
in the /lib directory.  In /bin I have init, sh and ls, copied from
/opt/hardhat/devkit/ppc/8xx/target/bin.

I seems the system expects to find the shared libraries in some other
directory than /lib.

I saw some discussion on the list about some symbolic links being
required
to get this
working, but I have tried everything I can think of.

Everything is fine if I use staticly linked binaries.

Can anyone give me directions ?
Does someone have a "minroot.tar.gz" made with HHL 1.2 ?
