Hi Sue.

The following info is IIRC - it's been a while I last
looked into a similar problem:

Have you installed the rtems cross-compiler into
a location different from the install location specified
when building the cross compiler (gcc configure options
--prefix & friends) ?

If so, then the first-choice of builtin search paths for
system headers, executables, libraries, etc.
won't work. Normally, gcc tries
a few alternatives which should work but this
is overridden by EPICS defining (for historical reasons?)

CONFIG.CrossCommon:

export GCC_EXEC_PREFIX = $(GNU_LIB)/gcc-lib/

I say in CONFIG.Common.RTEMS

unexport GCC_EXEC_PREFIX

and relocating my cross-toolchain then works.

For debugging this sort of problems gcc's

-print-<xyz>

options (not literally 'xyz' but the type of info you're
interested in) are your friends -- RTM. Make sure you
try these from an EPICS Makefile so that all other
options and environment variables as defined by
the EPICS build system are in effect.
