I have a weird problem with my C-Code that I don't really understand.
I have two header files os_memory.h and os_mem_drivers.h.
#ifndef OS_MEMORY_H_
#define OS_MEMORY_H_
#include "lcd.h"
#include "os_mem_drivers.h"
static const MemAddr gui_alloc_table_start = 0x1C8;
#endif /* OS_MEMORY_H_ */
#ifndef OS_MEM_DRIVERS_H_
#define OS_MEM_DRIVERS_H_
#include "os_memory.h"
#include "defines.h"
#include "os_core.h"
typedef uint16_t MemAddr;
#endif
If I try to compile this code the compiler gives me the error unknown type name 'MemAddr'. I don't get it because I included the right header files in each .h file so there shouldn't be any error.
Is there anything that I'm missing here?
I'm using AtmelStudio 6.1 and the C language for this project.
You should move the definition for type MemAddr before including "os_memory.h":
os_mem_drivers.h:
#ifndef OS_MEM_DRIVERS_H_
#define OS_MEM_DRIVERS_H_
#include <stdint.h>
typedef uint16_t MemAddr;
#include "os_memory.h"
#include "defines.h"
#include "os_core.h"
#endif
But a more important problem is the circular inclusion of "os_memory.h" and "os_mem_drivers.h". Each one includes the other: include guards prevent recursive inclusion but make it difficult to understand what is really going on. You should try and fix this issue.
