We definitely need to support OpenEmbedded style SDKs since they are
becoming more common.
I just wish they didn't force everyone to change how they use autotools
and make, and didn't rely heavily on a plethora of environment variables
that can easily cause obscure support problems.
While it was easy enough to get your Ettus/OE SDK to builid all prereqs
and OpenCPI, the required patches are not as clean as they need to be
and I did no execution of course.
I'll send you a patch file for the preliminary changes I made, but I
intend to create a cleaner solution for such SDKs in general "soon" as a
patch to 1.5.

I believed that specifying the same environment information in the rcc-platform.mk file the tools could be properly instructed. It is unfortunate to have to replicate information in multiple formats and locations but realistic when using multiple disparate toolsets. It appears to me that use of bash scripting in general requires awareness of the bash environment when passing commands to subsystems.

Xilinx also has a system and project standardization that enables everything to know where things are or should be. The only open-source projects I can think of that aspire to such goals and serve as wide array of targets as OpenEmbedded are Linux and GNURadio and even they can have their challenges.
