malloc()

Using malloc() gives me an error: Undefined identifier __DYNAMIC_HEAD


#include <stdlibm.h> is included


When compiling it opens up the file memmgmt.c and this is where the identifier __DYNAMIC_HEAD is located.

Why is is that it doesn't give an error of Undefined identifier for NULL as well, which is also in memmgmt.c ?

NULL, I realize, must be defined in CCS C.

Looking at the <stdlibm.h> file, the __DYNAMIC_HEAD is not defined.


Any thoughts?

NULL is actually defined in another called in <stddef.h>

But the __DYNAMIC_HEAD is not defined. I can't find it, anyway.

Am I missing something here?

Do you have the USE DYNAMIC_MEMORY directive?

I believe you need this directive to instruct the compiler to create the __DYNAMIC_HEAD object.

I placed the following directive at the top of my program, after the device directives:

#pragma USE DYNAMIC_MEMORY
