Objective-C + Cpp rvalues and arrays

Question

I need create array:

const UInt8 *pixels[3] = { yuvFrame.luma.bytes, yuvFrame.chromaB.bytes, yuvFrame.chromaR.bytes };

But Xcode show me error:

Cannot initialize an array element of type 'const UInt8 *' (aka 'const unsigned char *') with an rvalue of type 'const void *'

I am mixing C++ code with Objective-C. So how can I fix this? I need this const UInt8 *pixels[3]. Any suggestions?

Try the following initialization

const UInt8 *pixels[3] = 
{ 
    ( const UInt8 * )yuvFrame.luma.bytes, 
    ( const UInt8 * )yuvFrame.chromaB.bytes, 
    ( const UInt8 * )yuvFrame.chromaR.bytes 
};

In C++ there is no implicit conversion from a pointer of type void * to a pointer to an object of any other type.
