invalid initializer in gba

Question

im Lino, im new on this community. basically, im trying to save data into the GAMEPAK_RAM of the GBA, and the pointer dont work. the code line is this:

#define GAMEPAK_RAM ((volatile uint8_t*)0x0E000000)

and the error is this:

    In file included from source/main.c:2:0:
source/OpenEngine.h:8:21: error: invalid initializer
 #define GAMEPAK_RAM ((volatile uint8_t*)0x0E000000)
                     ^

someone can help me? if other info is needed, please tell me

Your code doesn't define or use GAMEPAK_RAM anywhere so it shouldn't give errors relating to GAMEPAK_RAM. — user253751, Apr 24 '18 at 00:33

You are supposed to include the *minimal* code needed to exhibit the problem, *in your question*, not as links to off-site resources; please check the Help Centre for more info on how to write a diagnosable, self-contained question. — underscore_d, Apr 24 '18 at 11:45

unsigned short *SaveMemory[0xFFFF] = GAMEPAK_RAM;

This is the same as:

unsigned short *SaveMemory[0xFFFF] = ((volatile uint8_t*)0x0E000000);

SaveMemory is an array and ((volatile uint8_t*)0x0E000000) is a pointer. You can't set an array equal to a pointer, hence the error.
