I just updated my laptop to ubuntu 15.10 (from 15.04).

And got into some intereasting issues.

I rebuild my game with the new compiler, and it doesnt link anymore.

I got a bunch of undefined references like below:

undefined reference to `Leadwerks::Window::Create(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int, int, int, int, int)'

This didnt make any sense, the program was linking just fine with the previous version of gcc (4.9.2).

After some digging i found the explanation:

https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html

It seems in gcc 5.1 a new abi was introduced, and the Leadwerks static lib was built with some previous version causing the above problems.

The solution i used was to add this macro at the begining of every cpp file in the project (in case of linux)

#define _GLIBCXX_USE_CXX11_ABI 0

Ths forces the use of the old abi and the game links just fine.

I suppose this wont be really a problem for Leadwerks, but was annoying to me.
