Unable to determine node size of C++ container

[razr]

While cross-compiling I get this error. It worked in 0.7-1

We switched to a new method of node size detection since then, and apparently your SDK cannot compile cmake/get_node_size.cpp. I don't have access to it, so I can't help you with that.

[razr]

It looks to me that you have broken the cross-compilation for your project which I fixed a while back, see #78

[foonathan]

We're no longer running anything, we're just compiling and inspecting the error message, so the emulator shouldn't be necessary, right?

[razr]

maybe it is a VxWorks-specific error, I don't know. I'm good for now with 0.7-1 :) Will try to fix it later.
