thank you for your effort! I did clone your 
https://github.com/cppljevans/spirit/tree/get_rhs into the sources and 
changed the CMake file accordingly , but run into compile errors now. 
The defines are taken from your responses, also your successfully 
finished compile log file above.

But following your links there seems to be  no easy solution yet. 
Fortunately it's a spare time project ...

Or, do I miss something?

Thanks,
Olaf
