I tried to change the order of loading library (i.e. loading NativeAdd
first and NativeC later, but android failed to load NativeAdd library,
probably because it was not able to resolve symbol ret_mul .

Removing iostream and using 'extern "C"' made the library which has only one
undefined symbol '__aeabi_unwind_cpp_pr0' which is available in /system/lib
arm-none-linux-gnueabi-nm libNativeCpp.so
0000029c a _DYNAMIC
000002f4 a _GLOBAL_OFFSET_TABLE_
U __aeabi_unwind_cpp_pr0
00000300 A __bss_end__
00000300 A __bss_start
00000300 A __bss_start__
00000300 D __data_start
00000300 A __end__
0000029c A __exidx_end
00000294 A __exidx_start
00000300 A _bss_end__
00000300 A _edata
00000300 A _end
00000260 T ret_mul_cpp
Thanks for the help.
But does this mean that all that big chunk of C and C++ source code that I
wanted to port to android will not be possible ?
I think Diluka had also experience problem porting his C/C++ code to
android.
Diluka, would you please comment on this. Could you port all your C/C++
source code to android? If yes could please give some points which I need to
take care while porting my C/C++ source code?
Thanks
