Linker errors in Android NDK (undefined reference to `__cxa_end_cleanup')

Android 中移植一个库(该库 使用了 libstlport )时 产生如下错误:

./obj/local/armeabi/objs/jniWrapper/native.o: In function `_Vector_base':
D:/opt/android-ndk/sources/cxx-stl/stlport/stlport/stl/_vector.h:73: undefined reference to `__cxa_end_cleanup'

  • After reading android-ndk/docs/CPLUSPLUS-SUPPORT.html I found that there a couple more libraries that I can link to:

                 C++       C++   Standard
    Exceptions RTTI Library system no no no
    gabi++ no yes no
    stlport no yes yes
    gnustl yes yes yes

    This stops my linker errors (and pushes the build onto a new set of errors :))

    Application.mk

    APP_STL := gnustl_static
  • Take a look here: Linux C++: Linker is outputting strange errors.

    In Android's Application.mk this would be:

    APP_CPPFLAGS := –frtti
  • You can fix this problem by adding the compiler option -lsupc++.

    Edited: The reason: your code is using C++ exception mechanism which compiler automatically generate try/catch/finally block hidden code which in turn call __cxa_end_cleanup somewhere. lsupc++ means link to libsupc++.a

    Another way to resolve this problem is add -fno-exceptions option to gcc which obviously means disable exception handler mechanism.

    BTW, you should also add -fno-rtti to avoid other maybe-encountered compilation error, this is because all android's C++ class is compiled without dynamic type info in class memory layout.

    In a word, you shoud use one of these option combos: 1. -fno-rtti -fno-exceptions 2. -fno-rtti -lsupc++
