Re: emacs-snapshot for arm

[alephnull@hcoop.net (Alok G. Singh)]

I've tried to setup a armel build environment using sb2 and the emdebian (lenny)
toolchain for armel.

$ sb2 -eR dpkg-buildpackage -uc -us

Running just the chown part causes no error. However, piping find
through xargs does cause the problem. http://bugs.debian.org/566026
seems relevant, but it's filed against fakeroot-ng, which I do not have
installed.

I cannot use the fakeroot inside the build env.

Embedded development and these toolchain gotchas have me beat, any help
appreciated.

TIA.
