multiple definition of `std::exception::~exception()'

[Ó. Egilsson]

I'm getting weird error when trying to use STL's vector:

/tmp/ndk/src/build/../gcc/gcc-4.4.3/libstdc++-v3/libsupc++/
eh_exception.cc:31:
multiple definition of `std::exception::~exception()'

Basically:

#include <vector>
std::vector<You> balls;
balls.push_back(You());

Any ideas ?

(Have the gut feeling it's my rusty C++'s knowledge to blame)

*** ANDROID.MK ***
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := jnitest
LOCAL_SRC_FILES := Simulation.cpp You.cpp

LOCAL_LDLIBS := -llog

*** Application.mk ***
APP_STL := stlport_static
APP_CPPFLAGS += -fexceptions
# I do need the exeptions in other places

Simulation::~Simulation() { }

void Simulation::addBalls() {
balls.push_back(You());
}

execeptions are only supported when using stlport. from the docs:

WARNING: IMPORTANT CAVEAT

     AT THE MOMENT, OUR STLPORT IMPLEMENTATION DOES NOT SUPPORT EXCEPTIONS
     AND RTTI. PLEASE BE SURE TO NOT USE -fexceptions OR -frtti IN ALL
     MODULES THAT USE IT.

     IF YOU NEED THESE, PLEASE USE "gnustl_static".

[İsmail Dönmez]

You mean only supported with "gnustl_static"

With gnustl_static I get different errors ...

Make sure you do a clean build.

[Ó. Egilsson]

Cleaned eclipse project and ran
ndk-build clean
still the same errors.

Thanks a bunch for slapping me with the documentation :)

Those errors fixed by defining constructor and destructor for You.
This compiles fine, so my real project has some other errors...
Using gnustl with it produces:

undefined reference to `std::__throw_length_error(char const*)'

Better make an better example to reproduce that error ...

[Ó. Egilsson]

Real project compiled fine after a wash with "ndk-build clean" like
suggested.
Better catch up on some sleep.

Thanks a lot!
