After some hacking, I've been able to build a toolchain based on binutils-2.19.1, gcc-4.4.0, and glibc-2.9, using the tc-fsl-x86lnx-armeabi-nptl-4.1.2-3.src.rpm (resultant SRPM attached).  I'm trying to use a i386 version build on Ubuntu 9.04, and running it on my x64 Ubuntu 9.04 (which has the 32-bit libraries installed and can run the 4.1.2 ARM toolchain to build up my ARM rootfs/kernel).

Unfortunately when I try to run the new toolchain on my x64 Ubuntu, it aborts with:

sudo /opt/ltib/usr/bin/rpm --dbpath /opt/ltib/var/lib/rpm -ivh --force --ignorearch /home/peter/work/logic/svn/LTIB/trunk/ltib-test/lpd-BASE-package-pool/tc-lpd-x86lnx-armeabi-nptl-4.4.0-1.i386.rpm

Any ideas where I can find a 32-bit verison of libmpfr I can load on my x64 verison?  I've hunted around and can find libmpfr, libmpfr-dev, but no lib32mpfr or lib32mpfr-dev components I can load with "apt-get install".

Any help is appreciated - thanks in advance!
