android.mk arm-linux-androideabi-g++ exceptions and __cxa_allocate_exception

Question

I am rebuilding Android from source (to flash onto a device, right now using emulator), trying to add a single command line tool. I've put my source in repo/exernal/... and written Android.mk.

I get the following undefines:

__cxa_allocate_exception
__cxa_begin_catch
__cxa_end_catch
__cxa_end_cleanup
__cxa_free_exception
__cxa_get_exception_ptr
__cxa_rethrow
__cxa_throw
__gxx_personality_v0

I've searched through the other issues here with the same undefines, but can't quite seem to find the solution for Android.

The final link command gets generated as:

Android.mk is:

include $(CLEAR_VARS)
LOCAL_MODULE := wavsender
LOCAL_MODULE_TAGS := eng
LOCAL_CFLAGS += -fexceptions -D_GNU_SOURCE -DPLATFORM_ANDROID
LOCAL_SRC_FILES += WavSender.cpp
LOCAL_SHARED_LIBRARIES := libc libcutils libnetutils
LOCAL_STATIC_LIBRARIES := libcutils libopenhome
LOCAL_STATIC_LIBRARIES += libopenhome libgtest libstlport_static libstdc++ libgabi++
LOCAL_LDLIBS += -lstdc++
include external/stlport/libstlport.mk
include $(BUILD_EXECUTABLE)

Can anyone see a problem or point me in a direction to get the correct behavior from arm-linux-androideabi-g++ ?

Answer 1

Consider removing libstd++ as a static in Android.mk it should default to the standard Android implementation and you should be fine

Actually, I see you added it both as a static and dynamic libraries.

Remove either static libstdc++ or the dynamic one. If that doesn't do it try removing both
