Hey Joey,

Would this be something you'd be interested in contributing to NDT? If so, is anything needed beyond the makefile listed below?

Cheers,
Aaron

Hey Aaron and Richard,

Thanks for putting me in touch with the dev team.  I was able to get it working with enough tinkering.  I ended up not trying to cross compile via the SDK but instead created an OpenWRT package and this seemed to do the trick:

jfreeland@slinky:~$ cat openwrt/trunk/package/feeds/packages/ndt/Makefile

# Let's see if this works..

include $(TOPDIR)/rules.mk

PKG_VERSION:=3.6.4
PKG_RELEASE:=3

PKG_BUILD_DIR:=${BUILD_DIR}/ndt-$(PKG_VERSION)
PKG_SOURCE:=ndt-$(PKG_VERSION).tar.gz

include $(INCLUDE_DIR)/package.mk

define Package/ndt
  SECTION:=utils
  CATEGORY:=Utilities

Could you send the logs when you have a chance? I've not tried cross-compiling NDT, but may be able to help debug.

Thanks for the super fast response and thanks for your work on NDT!  Unfortunately I'm on the go right now, but I'll give 3.6.5.1 a try soon.
