I tried to build the in-progress port of EPICS for the uC5282 BSP last night
against a release build of RTEMS-5.1 with tools and BSP built using RSB. It
looks like the g++ cmath routines haven't been configured properly for this
target. It failed at the first C++ source file includes math.h (other BSPs such
as the beatnik and qoriq_e500 get further than this, and only the pc686 build
completely succeeds right now):

There could very well have been errors building the BSP on my part as I had to
hand-create a uC5282.bset file for RSB to build it:
> tux% cat config/5/bsps/uC5282.bset
> %define mail_single_report 1
>
> %define with_rtems_bsp uC5282
> %define rtems_target m68k-rtems5
> %define rtems_host %{rtems_target}
>
> 5/rtems-m68k
> 5/rtems-kernel
> 5/rtems-libbsd
The libbsd line there might be wrong, but I wouldn’t expect that to affect the
availability of <cmath> functions to the C++ compiler.
Any suggestions?
Thanks,
