[Buildroot] cp -dpR fails on BSD systems -- advice on resolving?

[Buildroot] cp -dpR fails on BSD systems -- advice on resolving?

[Allan Clark]

Hi everyone;

I ran into a problem when I moved from uclibc-snapshot to
uclibc-0.9.28 or 0.9.29: the "cp" command is a non-Unix option: "cp
-a" or "cp -dpR", or "cp --no-dereference"

I assume it's on Linux, and works, so those of us doing something
funky (like BSD or MacOSX) invite a few problems.

I'm wondering if the fix should be:
1) submit compatible patches to the group, using an older
syntax/options for all hosts, or
2) detect, and download/build/use a replacement (same way I did for
gmake, as was done for sed)

OT: Any particular reason you're using a Chinese charset? Anyway, issues
of cp have been discussed before on this list. And there are bug reports
about it in the tracker. I suppose nothing conclusive was ever reached.
In the case of uClibc, one could imagine replacing the cp with the tar
trick that's used in the SVN trunk, but the problem, as you surely know
by now, has much wider manifestation over buildroot, and should be dealt
with some uniform, generally agreed upon, way everywhere.

This is http://bugs.uclibc.org/view.php?id=944
Please followup there (would be nice if we could fix this once and for
all).
