Thread: Operations between types "struct _object*" and "int" is not allowed

The part of the code that is causing this error is:

Code:

newobj = STRINGLIB_NEW(NULL, STRINGLIB_LEN(self));

I have tried to undefine the variable and malloc.
I am not sure how to correct the error.
Also I am compiling this with the ILE C AS400 compiler
The following is the entire code.....

Code:

 /* Do not use it with Unicode. */
 #include "bytes_methods.h"
 #include "structmember.h"
 #include "stdlib.h"

     return newobj;
 }

update: I found the solution........
I defined a struct as an int "#define objectint(b) *(uint8_t*)&b" and then I went to the offending
line of code and change "newobj = STRINGLIB_NEW(NULL, STRINGLIB_LEN(self));" to
"objectint(newobj) = STRINGLIB_NEW(NULL, STRINGLIB_LEN(self));"
