Newer Linux distributions use libraries that are incompatible
to those used by the ELDK's installation tools.
This problem was fixed in later releases of the ELDK (version 3.0 and later).
It is therefore recommended to use a more recent version of the ELDK.
If you really want to install an old version,
the following back-port is available:
Please download the file
ftp://ftp.denx.de/pub/tmp/ELDK-update-2.2.0.tar.bz2
Then change into the source tree with the ELDK files and perform the following operations:
bash$ rm RPMS/rpm-4.0.3-1.03b_2.i386.rpm \
RPMS/rpm-build-4.0.3-1.03b_2.i386.rpm \
RPMS/rpm-devel-4.0.3-1.03b_2.i386.rpm \
tools/usr/lib/rpm/rpmpopt-4.0.3
bash$ tar jxf /tmp/ELDK-update-2.2.0.tar.bz2
Then build the ISO image as documented, and try again.
