RE: Problems linking PSIM programs

["Wealand, Barry" <barry dot wealand at lmco dot com>]

Thanks, folks.  I've had better luck with later versions of the compiler
too, as I mentioned (gcc 3.4.4 with binutils 2.14 works fine).  There
just seems to be something about gcc 2.95.3 that somehow leads to this.
I've even moved everything to a Linux host platform - this produces the
same results.

For sake of completeness, I've attempted to build binutils 2.17 as
suggested, also for a Linux host and powerpc-eabi target.  This does not
build (using native gcc 3.3.4 on the Linux machine).  A whole slew of
errors are reported when building bfd, compiling module elf32-ppc.c.
The errors seem to occur in an include file, elf32-target.h, the first
from line 468:

elf32-target.h:468: error: `false' undeclared (not in a function)

Have I missed any new required steps for configuring and building
binutils-2.17?  (2.12 configures and builds on this machine just fine.)

I failed to mention that the interest in the older compiler comes from a
desire for (as near as possible) code generation that's similar to a
WindRiver GNU compiler we're using (they call it 2.96, apparently based
on 2.95.3).  That's where all the older version numbers come from.

Thanks again!

psim is one of the platforms we regularly test RTEMS on.  But we use
much more recent tools than that.  gcc 2.95.3 is quote old also.

gcc 4.1.1 + binutils 2.17 works great.
