Looks like a 64 bit problem. Could you try applying this fix in sugar-jhbuild/source/squeak?

Actually, I committed the proposed fix so you can simply "sugar-jhbuild buildone squeak" to try.

[sascha_silbe]

Your patch (applied it manually) did the trick, thanks! Astonishing what a difference a single word can make. :)

While I had just look at the wrong source again (etoys instead of squeak), I probably wouldn't have been able to fix it myself anyway (without a lot of research about squeak internals).

Replying to sascha_silbe:

Hehe, great!

While I had just look at the wrong source again (etoys instead of squeak), I probably wouldn't have been able to fix it myself anyway (without a lot of research about squeak internals).

"squeak" in jhbuild is the platform-dependent part, the virtual machine, written in Smalltalk and C . "etoys" itself is platform-independent (all Smalltalk).

I think we can close this.
