Hi Rene,
Thanks for the heads up.
Here (attached) are patches to get perl to cross build.
The perl cross build (on Mips) has been broken for years, back in 2011, I was just rolling
back to an earlier version to get it to work. I put some time into it, and now have the
latest version cross building.
The install process for perl now calls Porting/pod_lib.pl which makes use of the cpan/md5
modules.
Since the cross build uses a native miniperl, and not the real perl, the md5 related calls
were failing. I first tried to get the MD5 modules built into miniperl, but could not get
that to work, so I back-ported the older install method from an earlier perl version that
did not have the MD5 dependencies.

Hi Jan,
just a heads up: the last months we (at ExactCODE) were way too busy with projects not
related to T2. So unfortunately from our side we put less time in using and polishing T2
as we did before with certain embedded projects.
Of course that may change every other quarter as we have projects coming in and
such, …
Patches welcome! Guess I should update T2 on my G5 for the cross build test of
it, … ;-)

Hi,
I am going through a T2 cross build for Mips64 (octeon processor) on a 32-bit ubuntu
11.10 (Oneric) build host. The last time that I tried the mips64 build was 2011, and it
needs a lot of updating.
I will be reporting my progress as I go, and sending patches as they are
discovered.
The first thing that I ran into was that glibc stage 0 would not build. it may be
something specific to my build host, or to the mips target selection. First, I was
getting configure errors where the test for hard or soft float was failing. I had soft
float set in my T2 config file, so I modified configure to default to soft float, if it
could not determine the test, just to get through the configure stage. (looking back on
this, since it's stage 0, soft float does not matter, since it's going to build for
x86, not mips).
This allowed me to get to the build stage, but during the compile I was getting errors
that __WORDSIZE was not set. this was down in the mips specific directories. In
looking at the .h files that set this, there is an attempt to set __WODSIZE to
MIPS_SZPTR. and my native gcc on the ubuntu machine has no definition for MIPS_SZPTR.
For a stage 0 build, I am puzzled why it is going into the MIPS specific code, I
thought that it should be a straight x86 build at this point. After wasting most of the
day on this and not really getting anywhere, I decided to roll back glibc from 1.17 to
the previous 2.13. That version built OK, with some very minor tweaks. I would like to
get to the bottom of why 2.17 will not build, but for now I will stick with 2.13, an d
continue.
I am currently working on the stage 1 perl build, which is broken.
