undefined references to cxa, gxx and cxx functions

[ParanoidAndroid]

I get some errors like those below. I think it has something to do
with missing ARM EABI libraries. Any ideas?

home/mike/dev/sdks/android-ndk-1.6_r1/apps/test/project/libs/armeabi/
libBasicUsageEnvironment.a(DelayQueue.o): In function

What did you do exactly to get these errors ?

I compiled live555 with the NDK as static libraries and now I am
trying to include those libraries within my Android native code where
I use a C++ file. Taht file has 2 includes:

#include <liveMedia.hh>
#include <BasicUsageEnvironment.hh>

The errors occurs whenn I call my Android.mk file.
The problem is seems to be with the second include. The first one does
not cause an error.

Hi Paranoid,

Exceptions and RTTI won't work in Android.

The link errors you are getting are related to RTTI (run-time type info). Normally, C++ code should be compiled with -fno-rrti flag. But if you do use dynamic_cast and other RTTI-related calls, then it won't compile neither.

Are you sure you use the NDK-provided gcc builds, an not only the NDK libraries ?
