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 ?
Regards,
Jon Benediktsson

that 's right! If you use hhl 1.2
you should have a link to /
/opt/hardhat/devkit/ppc/8xx/powerpc-hardhat-linux
as you have in your NFS root filesystem.

I don't have, but minimum ramdisk is depend on
which application you want to support.
if you just want to boot , configure IP address, mount, see my list:
other dir is empty

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.
