When link fmod with other C++ codes using Android NDK, it requires program link with libc++ instead of libstdc++, however libfmod.so was built for libstdc++ even with ver 2.02.07

In this thread you claimed that STL is no longer required [libfmodstudio and c++11 - #5 by jpopcenter](https://qa.fmod.com/t/libfmodstudio-and-c-11/11281/5)

But I still got those errors

libfmod.so: undefined reference to `__cxa_guard_release@LIBC_O' libfmod.so: undefined reference to `\_\_cxa\_guard\_acquire@LIBC\_O’  
libfmod.so: undefined reference to `operator delete(void*)@LIBC_O' libfmod.so: undefined reference to `\_\_cxa\_pure\_virtual@LIBC\_O’
