FWIW (should not matter, here): The offical target name is
"sparc-rtems4.10".
Thanks Ralf - I'll change the scripts (although as you say it
shouldn't make a difference).
All patterns in all binutils, gcc and gdb configuration scripts are
supposed to match on "sparc-rtems*", so it should not actually matter.
FWIW, I just built sparc-rtems on linux (Fedora 13) without incident from
the 7.2 tarball, so it should work for you, too.
I am building all *-rtems targets fairly frequently without many problems
(cf. ftp://ftp.rtems.org/pub/rtems/linux/4.11).
However gdb's dependencies are a royal pain and occasionally cause building
gdb produce bizarre errors. Which host OS are you using?
I'm using MinGW under Windows 7. If that's likely to be a problem I could
set up a VM for Linux.
It likely is a problem.
I am building mingw32 RTEMS packages Canadian-cross under Fedora
c.f. http://www.rtems.org/ftp/pub/rtems/mingw32
http://www.rtems.org/ftp/pub/rtems/mingw32/4.11/rtems-4.11-sparc-rtems4.11-gdb/
contains sparc-rtems4.11-gdb-7.2
(Despite the target name, these packages should also be usable with
rtems4.10.)
It all looks OK, and the makefiles seem to be sensible, but I'll check through
it again. I've done a diff between the "sparc-rtems" and "sparc-elf" versions
of the build and nothing obvious jumps out.
I have no idea. As you correctly found out, sparc-rtems*-gdb and
sparc-elf*-gdb are almost identical.
The only real difference is the official RTEMS packages have patches
applied, which are not in FSF's gdb.
Dunno, if you are using these patches - If so, timestamps could make a
difference.
However none of our patches explain your breakdown.
