Experimental Physics and
Industrial Control System

Hi

it would be lovely if the experts who have done stuff like that before
could help me with this one, even though this is not strictly speaking,
an EPICS matter.

My goal is to build the RTEMS cross tools from source under ubuntu. I
tried the manual procedure as described in [1], as well as the debian
source package from [2]. I tried building on 32bit Ubuntu precise, and
64bit ubuntu saucy and (lately) 64bit trusty.

The build always fails at the same point, output displayed below. Note
that in this case I built with nix (therefore the strange path names),
but it makes no difference if I do all the steps manually (/tmp/nix-
build-gcc-powerpc-rtems4.9.drv-1/ is the temporary directory with the
downloaded sources and the build-powerpc build directory).

I'd very much appreciate any kind of hints as to what can be done about
this.
