Hi,
I have a Perl module, which uses Perl internals and doesn't use them
right on
big-endian platforms (see
http://analysis.cpantesters.org/reports_by_field?distv=Regexp-
Compare-0.12;field=conf%3Abyteorder for details). Since I don't have
big-endian
hardware, I'd like to debug the problem under a simulator, and
scratchbox
seems like it should be able to do it - almost... I tried ARM
emulation for
Maemo (which I had lying around from a previous project), only to
find out that
the L in FREMANTLE_ARMEL apparently stands for little endian :-)
(and, on a
more positive note, that the emulation can compile perl, at least
5.8, which
should be enough)... So, what is the best (simplest to install, most
stable)
scratchbox toolchain for a big-endian platform?
Compiling perl modules with scratchbox is possible, but not too easy
nor straightforward.
With scratchbox 1 one has to do special tricks when compiling perl
modules (I assume that you are using SB1, as you refer to fremantle)
and with SB2 it is one of those things that can't be done with the
"simple" mode (there "accel" and "devel" modes should handle the
trickery automatically, but I don't know any complete SB2-based big-
endian SDKs)
The safest & simplest solution in this case is probably to use Qemu in
full-system mode with a big-endian complete Linux distro. Slow, but
safe.
