I get "call of overloaded ‘to_string(double)’ is ambiguous" error when compiling with -std=c++11 on Kubuntu 14.04.1, using Flightgear from GIT release/3.2.0 at 2014-09-21.
C++ 11 has to_string() also:

Here's original bug report for Flightgear:
https://code.google.com/p/flightgear-bugs/issues/detail?id=1551
This should now be fixed in CVS.
Could you please check and let us know if the problem is fixed on your side as well ?
FYI the fix has been ported to FlightGear.
Yes, Flightgear from next branch compiles fine now (with exception of std::auto_ptr deprecation warning).
Thank you!
