I am trying to cross-prelink a simple hello world program. I use the cross-compile toolchain arm-2012.03-57-arm-none-linux-gnueabi-i686-pc-linux-gnu and I am not sure if I have used the prelink-cross options correclty. I'll be glad if someone could point me to the right direction. More details about the source code on github. Thank you.

If I extract all the libraries that the executable is dependent on into a separate folder and set the links accordingly, then I still get the following error:
prelink: bin_arm/hello: Could not parse `/usr/local/sbin//prelink-rtld: error while loading shared libraries: ld-linux.so.3'
Yay, I found the solution:
I had to specify the sysroot and explicitly tell prelink which libraries to precompile.
The directory structure now looks like this:
|- arm-2012.03/arm-none-linux-gnueabi/libc/usr/local/bin/hello
\- /arm-none-linux-gnueabi
\- libc
\- lib
\- libc-2.15.so
|- libgcc_s.so.1
|- ld-2.15.so
|- ...
|- usr
\- local
\- bin
\- hello
|- etc
\- prelink.conf
|- Makefile
prelink.conf
-l /libc/lib
-h /libc/lib
And this is the prelink command:
PATH=/usr/local/sbin prelink --verbose --root=arm-2012.03/arm-none-linux-gnueabi/libc/ --cache-file=/etc/cache/prelink.cache --config-file=/etc/prelink.conf --ld-library-path="/lib;" -h /usr/local/bin/hello /lib/libc-2.15.so /lib/libgcc_s.so.1 /lib/ld-2.15.so
