Hi,

I am trying to use yagarto (arm-elf-gcc 4.3.3) for STM32.
Everything works ok if I don't use printf.
But I need to use printf, so #included <stdio.h>. It produced error:

In file included from main.c:31:
C:\SCARM\GNUARM\arm-elf\include/stdio.h:190: error: expected declaration specifiers or '...' before '__gnuc_va_list'

Did not know the right way to overcome this error. So I added these
lines in main.c before #include <stdio.h>

#ifndef __GNUC_VA_LIST
#define __GNUC_VA_LIST
typedef void *__gnuc_va_list;
#endif

Then I could compile without errors, but linker produced many errors of
this type:

../arm-elf/bin/ld.exe: ERROR: stm32f10x_gpio.o uses FPA instructions, whereas Hello.elf does not

Does it mean that the newlib that came with yagarto is compiled using
FPA? Does it mean it can not be used for Cortex-M3? Is there a solution?

Thanks and Best Regards,

Ajeet
