ELDK on 64-bit host

Hi,

I tried to copy the ELDK 4.0 installation I had to a new Core 2 Quad
machine running 64-bit Ubuntu 7.10, but the new machine refuses to
execute the cross compiler. Has anyone succeeded in running ELDK in
this kind of environment?

I also tried compiling the ELDK from source RPMs as described in the
documentation, but at least some of the RPMs the scripts try to
download are no longer available on the net, and the build environment
described doesn't seem to quite match the one on the source rpm ISO
image.

Yes (at least with 64-bit Debian on a single core Xeon), but you need
a special library on the host.  I think it's call 'ia32-libs'.  It
should be available via aptitude.

Thanks, that was indeed the correct library to install. Now it works just 
fine.

I'm a bit surprised there wasn't really any useful search results from 
Google with obvious keywords. I was already about to install the 32-bit 
version of Ubuntu to get the compiler working again. But then, perhaps 
installing this library was obvious to everyone else :)

We added an FAQ entry[1] to our DULG documentation.  And just as a
reminder, there is also an ELDK mailing list for such questions[2].
