Ignore my last email. I changed in the wrong source tree. It now builds correctly.

	Many thanks for your help Ralf & Chris.

Have tried what you suggested but still get the same problem, build output for app shown below:

With rtems-4.6, implement a for your driver, add this
Makefile to your BSP's and add the BSP side to BSP_PIECES
in lib/libbsp/<cpu>/<bsp>/wrapup/

With rtems-CVS, add a "*.rel" block
(cf.lib/libbsp/<cpu>/<bsp>/ to
lib/libbsp/<cpu>/<bsp>/ and let add the '*.rel" to

In both cases, after editing the the
cd lib/libbsp/<cpu>/<bsp>

cd builddir
.../configure ....
