Yes, this is the real reason for the compile failure because g++-4.9
does only provide the old C++11 abi, but ... 

Since gccxml is abandoned by upstream in favor of castxml [1],
libgccxml has not been updated to work with g++-5 - it may compile with
g++-5, but when it is used to parse code in order to get the xml-files
that are then used to create language bindings it will choke on g++-5
provided headers, which means it is on no use on systems with g++ >= 5
as the default compiler. 

Best,
