hello all,
I'm trying to compile the microblaze-toolchain from source on a 64 bits
linux system, but got stuck. The source from the petalogix repository
doesn't compile. a first problem was solved with help of colleague:
a declaration error in 2 header files of binutils/gas (just wondering if
this is done on purpose by petalogix..). Anyhow, compilation proceeded with
building of gcc, but it stopped after the first xgcc line after
mkinstalldirs libgcc etc. I subsituted as cflag -m32 to force 32 bits cross
tools and the build process got a bit further, but still an error. The
following line is stopper:

Somebody any idea how to solve this?
Anybody succesful with building this toolchain with a 64 bit linux system
(it's running suse 10.2)? 
Anybody willing to put a ready-to-run toolchain in a tarball somewhere?

I can assure you the source tarball you found on the PetaLogix website 
is the same as was used to build the gcc at that time.  It builds fine 
on a RHEL/CentOS 3 machine, such as the one I am using right now.

Hello john, 
are you sure? I just did everything again in a clean directory. Executing
do_everything results in:
/usr/local/microblaze/microblaze-toolchain-sources/srcs/binutils//gas/config/tc-microblaze
.h:63:
error: array type has incomplete element type
and the compilation stops.
The solution is to move the struct relax_type from tc.h to as.h in
srcs/binutils/gas and remove the forward declaration from as.h. It's just a
simple order, but I assume that this also will not work on a RHEL system
without doing this unless your gcc compiler works different.
(a colleague running ubuntu had the same problem by the way)

After this modification the same script continues but stops again in the gcc
phase:
mkdir -p -- libgcc
mkdir -p -- bs
mkdir -p -- libgcc/bs
mkdir -p -- m
mkdir -p -- libgcc/m
mkdir -p -- bs/m
mkdir -p -- libgcc/bs/m
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

Well, this one is perhaps more related with the compiler/64 bits
environment. so I changed do_all_gcc.csh with the -m32 flags and this gives
the already mentioned error (libgcc2.c compilation):
/tmp/ccYgSyAu.s: Assembler messages:
/tmp/ccYgSyAu.s:124: Error: operand must be absolute in
range -2147483648..2147483647, not -1042284544
If you've any idea, that would be very nice.
