libc.so.6 error but not in Montavista

libc.so.6 error but not in Montavista

[David de Andrés Martínez]

I am trying to build a ramdisk for a TQM823L module using the LinuxPPC
(2.4.4) and CDK provided by DENX.

I have built the CDK withouth any problems and so the ramdisk.
But when I try to boot the system, I obtain the following error:
....
EXT2-fs warning: checktime reached, running e2fsck is recommended
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 52k init
init: error in loading shared libraries: libc.so.6: cannot open shared
object fi
le: No such file or directory
Kernel panic: Attempted to kill init!
Rebooting in 180 seconds..

I have been searching the lists for a solution but it seems that people
with the same problem were using the Montavista version, not the DENX
one.
The proposed solution for Montavista is:
--------
If your shared libraries are (as usual) in the "/lib" directory, add the
following option to the GCC command line when linking your binary:
-Wl,-R/lib
--------
In fact, I don't know where to add this option.

The /lib/libc.so in the ramdisk shows the following code:
---------------------
/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
GROUP ( /LinuxPPC/CDK/lib/libc.so.6 /LinuxPPC/CDK/lib/libc_nonshared.a )
---------------------
I think that this isn't right.

Any help would be great.

There is a patch for our old version of the cross tools; see
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/patches/specs.tar.bz2

This fixes the compiler "specs" files to automatically add this option.
