[ELDK] ELDK with x86 target

Thanks for your quick response. I'd love to help you start an x86
target project, but unfortunately my company's x86 product is a legacy
product that we may never even need to upgrade. Given that, it's hard
to justify the effort that would be required to create a real cross
compilation environment, so I think I'll probably go with the
quick-and-dirty approach of building Fedora 8 packages on a Fedora 8
Also, when you say that 4.2 is based on Fedora 8, I assume that you're
referring to the packages that make up the ELDK4.2, but not the
environment to build ELDK4.2, right? My experience from the past few
days has lead me to believe that if you want to build ELDK4.2 from
scratch, you're still best to go back to a Fedora 5 distro. I'm not
sure I have any reason to build from scratch anyway... I think I
immediately jumped in and tried to do that because of my "traditional"
embedded build process mindset.

Note that ELDK 4.2 is based on Fedora 8, so that could be your base
for such work (and actually this is what we would recommend in such a
But I am well aware that a controlled toolchain environment like the
ELDK has it's advantages even for x86 host / x86 target combinations.
Like in so many other cases it's the effort that stopped us from
providing such a version yet - respective customers who needed this
so urgently that they would be willing to cover at least some
significant part of this effort.
The alternative would be to start such a version as community
project; I'd be happy about such a thing.

The quick and easy way to get something that is pretty close to ELDK
4.2 is to install Fedora 8, eventually under some emulation/virtuali-
zation layer like qemu or so.
Or we try and start an x86 port of ELDK as community project.
