Well unfortunate is that Emacs' Makefiles make a number of assumptions
that are completely incompatible with cross-compilation :) Like
compiling and executing the resulting program in a single Makefile rule.
The dumping is even more hackier. Didn't even know that such a
procedure is possible on current operating systems :)
The problem with a simulated environment, that you're suggesting, is,
that OpenWrt packages (or rather the recipies used to compile a package)
need to be self-contained inside OpenWrt. If I needed a target system
emulator I'd have to write a recipie how to compile one on any host and
add a build-dependency to it. Quite some work, and maybe not even
possible in a completely stable way. Qemu user-space emulation for the
MIPS32 target seems currently broken (at least it doesn't work for me),
so I'd even need to write a rule for how to generate a root-filesystem
to get into a simulated environment. And that would have to work for
every of the target CPUs that OpenWrt supports :/

Going to do that eventually.

Hmm, so maybe related to the CANNOT_DUMP config (note: it's not NO_DUMP,
my mistake).

Ok, thanks for the answers. Then it might be time to do some more
in-depth debugging to see where in loadup.el that entry originates.
cheers,
David
