[Development] Using gcc to build arm version

[song.7.liu at nokia.com]

Another thing: it seems that the libstdc++.so is based on Linux OS, so it can't be used for target build...

So for the gcc/g++, is there a standalone library for c++ support ?

Thanks,
Song

readelf -s -W libsupc++.a | grep UND, still shows:

_ZTVN10__cxxabiv120__si_class_type_infoE
_ZTVN10__cxxabiv121__vmi_class_type_infoE
_ZTVN10__cxxabiv117__class_type_infoE

Thanks,
Song

libsupc++.a is included in libstdc++.so, which comes with most GCC
installations.
