Hi,
I tried to compile my own program with eclipse and GCC with c/c++. I followed this tutorial : TUTORIAL
I have some problems :
-
First : i have problem with SEGGER RTT lib compilation
SEGGER_RTT_Syscalls_GCC.c:63:21: warning: its scope is only this definition or declaration, which is probably not what you want
SEGGER_RTT_Syscalls_GCC.c:98:21: warning: 'struct _reent' declared inside parameter list int _write_r(struct _reent *r, int file, char *ptr, int len) { ^
SEGGER_RTT_Syscalls_GCC.c:98:5: error: conflicting types for '_write_r' int _write_r(struct _reent *r, int file, char *ptr, int len) { ^
SEGGER_RTT_Syscalls_GCC.c:63:5: note: previous declaration of '_write_r' was here int _write_r(struct _reent *r, int file, char *ptr, int len); ^
make: *** [src/Segger_RTT/SEGGER_RTT_Syscalls_GCC.o]
et le contenu du fichier syscalls :
#include "SEGGER_RTT.h"
int _write(int file, char *ptr, int len);
int _write_r(struct _reent *r, int file, char *ptr, int len);
int _write(int file, char *ptr, int len) {
(void) file; /* Not used, avoid warning */
SEGGER_RTT_Write(0, ptr, len);
return len;
}
int _write_r(struct _reent *r, int file, char *ptr, int len) {
(void) file; /* Not used, avoid warning */
(void) r; /* Not used, avoid warning */
SEGGER_RTT_Write(0, ptr, len);
return len;
}
- Second : i have problem with memory and standard libraries. (like iostream)
when i use standard lib iostream:
c:/gnutoolsarmembedded/5.42016q2/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: test.elf section .text' will not fit in regionFLASH'
c:/gnutoolsarmembedded/5.42016q2/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: region `FLASH' overflowed by 156012 bytes
I saw on google, that is a memory space problem. My .hex is too big.
If someone had same problem or solution.
Regards,
