This seems unacceptable to me. Depending on what is wanted for
any given situation, I agree that trade-offs must be taken. I
would much prefer to less segmentation than to have to recompile
and relink for every download. On each "host" connected to my
"target", I want a bunch of applications. I accept the need for
a download manager (on the host) and a program manager (on the
target), but I don't accept the need for cross-compilation and
linking tools on the host.
At this point, I like Joel's recommendation of the linker option,
but I didn't know that existed. I have to look into that.
These are all great options!
Cheers,
Jake
