Hi,

The C++ standard enstablish that the linkage is part of a symbol signature and you are passing a C++ function as an argument that requires C linkage, that is they have different types.

Declare you function as extern "C" or enable the GCC extensions.

Hi,

I agree with Alberto suggestion. Please mention the details of board/device and package using by you. In addition that, refer the NDK helloworld example project, if you use BIOS-MCSDK_2
