Hey Boris,

thx for your clarification - seems the procedure works better when I use 
version 17 of the
android ndk.
I'm still in the compilation process, so I can probably report back once 
it is finished.

Given the earlier mentioned errors just disappear when using the 17 NDK, 
I wonder how/if it is possible
for the odb compiler (on the host machine) to generate valid c++ code 
for the target, when the target probably
uses a completely different standard c/c++ library and has no support 
for GCC at all.

I do not want to go this way either if not possbile, sounds like pain to me.
Does that mean you have tried to use odb on a recent android ndk >= 18?
