I have built a toolchain with crosstool-0.28-rc34 for arm-iwmmxt. I used gcc-3.4.0, glibc-2.3.2, binutils-2.14.90 and linux-2.6.8.1 kernel head files. I find it is needed to add GLIBC_EXTRA_CONFIG="--without-fp" in arm-iwmmxt.dat, or there is an error report: selected processor does not support "rfs r2". Then it progressed well.
The toolchain can be used to compiled linux-2.6.8.1 kernel. But there
is a weird feature about this toolchain. I built a linux-2.6.8.1
kernel image and busybox with it, then I run it in a xscale board, it
always report: illegal instructions when the busybox is loaded. I
overwrite the libc-2.3.2.so with an old one built with an old
toolchain, then it works fine.
Try building busybox static with the new glibc, and seeing if it works on a system with the old libc-2.3.2.so. If it still fails, you can then use gdb or something like that to find the problem.
Alternately, you might try glibc-2.3.3 or glibc-20000827, which are newer and might have important fixes, who knows.
Do you have the sources and build script for the old libc-2.3.2.so? Or a URL where it came from?
Finally, you should also bring up this problem on the arm-linux or arm-linux-toolchain mailing lists if you don't get enough help here. Please let us know what happens in the end. - Dan
