GNU Smalltalk and cross-building images

Hi Paolo,

for the OpenEmbedded integration I will need to build a GNU Smalltalk image
for ARM/PPC 32bit on maybe a AMD64 build host. Right now I only have the need
to build an image, any ideas how to approach this best? A script to convert
images, dedicated image writing?

My current deployment script is:

Eval [
    | name img |
    name := Smalltalk arguments at: 1.
    img := Smalltalk arguments at: 2.

    (PackageLoader packageAt: name)
        fileIn;
        start.

    ObjectMemory
        snapshot: img;
        quit.

]

32-bit to 32-bit should work across hosts, even cross-endianness
(modulo bugs which should be fixed easily).  Just use an i686 binary
on the AMD64 host.

Can you set me up to look at debian multiarch?  Thanks,

Paolo

Feel free to send me a public ssh key.

Then I don't care.  Sorry.  You don't break 20-year-old conventions and
invent new toolchain options without bothering to contact upstream gcc.

It us added later, compare these:

$ gcc -print-multiarch             # on Debian unstable
x86_64-kfreebsd-gnu
$ gcc --print-multi-os-directory   # on Fedora
../lib64

I agree, it is insane to have that crap. On the other hand GNU Smalltalk is
probably not important enough for Canonical to fix that. But thanks for your time.

okay, I will verify it is working on kFreeBSD64/debian and then don't care for
this version of Ubuntu.
