hi all,

i am trying to implement embescom application note 6 but during the initial setup iam getting this error.

or32-linux-gcc -mhard-div -O2 -c -o support.o support.c
In file included from support.c:8:0:
support.h:45:20: error: macro "putc" requires 2 arguments, but only 1 given
support.h:45:6: error: �putc� redeclared as different kind of symbol
make[2]: *** [support.o] Error 1



can anyone help me....

Hi Tarun

Yuk. This shouldn't happen. This is a bare metal application, so must define all its own functions. This should be fine, but somehow it is picking up the system definition of putc (which is a macro). I suspect the problem is in the conditional code for the OpenRISC. You'll see that support.c has the code:

#if OR1K

/* Register access macros */
#define REG8(add) *((volatile unsigned char *)(add))
#define REG16(add) *((volatile unsigned short *)(add))
#define REG32(add) *((volatile unsigned long *)(add))

void printf(const char *fmt, ...);

/* For writing into SPR. */
void mtspr(unsigned long spr, unsigned long value);

/* For reading SPR. */
unsigned long mfspr(unsigned long spr);

#else /* OR1K */

#include 

#endif /* OR1K */

I can only think that OR1K is not getting defined by the compiler, so stdio.h is being included. Try explicitly definining this:

or32-linux-gcc -DOR1K -mhard-div -O2 -c -o support.o support.c

This is quite an old application note, using an obsolete version of SystemC, so you may need to fix some of the SystemC code if interfaces have changed.

hi jeremy

thanks for ur reply..
i have included -DOR1K in the make file of both support and dhry folder, make file of support folder is bulding properly but i am getting this error while runnig the make file of dhry folder.

Hi Tarun,

There is a problem with building the verilator model. I'd look at the detailed error message inside the verilator-model directory.

HTH,
