`-rpath DIR' Add a directory to the runtime library search path. This is used when linking an ELF executable with shared objects. All `-rpath' arguments are concatenated and passed to the runtime linker, which uses them to locate shared objects at runtime. The `-rpath' option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the `-rpath-link' option. If `-rpath' is not used when linking an ELF executable, the contents of the environment variable `LD_RUN_PATH' will be used if it is defined.
My problem occurs not at run time, but at link time.

Works fine for me.
It looks like you need an rpath specified. Try adding:
-Wl,-rpath /home/sjackman/lib/newlib

When trying to link "Hello, world!" with a native shared newlib library, I get this hidden symbol error. The same application links perfectly with -static.
Thanks in advance for any help you can give.
Please cc me in your reply. Cheers, Shaun
