I'm using an atmel 2051 with the Franklin Proview, and am trying to create a dynamic array, to read data off the serial port

The following code (which I wrote just for this question so is only an example) compiles fine indicating that I want 7 Blocks of memory, where each block is 1 byte long)

#include <stdlib> // for malloc....


void someFunction(void)
{
byte *ptrData; //pointer to the located array of incoming data

ptrData = calloc(7,1);

}

However when it comes to linking the program I get the following error

Error 100 : Unresolved External Symbol: _calloc(Myfile)


Any ideas; or any other ways to declare a dynamic array.

Thanks
