You seem to be missing some library. If any library (or library needed
by another library) isn't loadable, you get this error.
Maybe you forgot ld-linux.so ?
Compile youe hello program and run "ldd hello" to see what libraries you
need.

No such problems (except like forgetting libs or wrong permissions).
What architecture are you building for? Do you have a linux on that
system, so you can setup a chroot to the ramdisk to be? Using chroot
is a quick way to test if a ramdisk would work.
