Hi again,

I have got the build working. Here is a foo.c and a
simple Makefile that runs with CodeSourcery's 3.4.3
toolchain:

/*
 * foo.c
 */

#include <common.h> 
#include <exports.h> 

int main (int argc, char *argv[])
{
	app_startup(argv);
	printf ("Voila! Voila!");
	return (0);
}

The Makefile:

# Makefile
# Tools

CROSS	=
/usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-
CC	= $(CROSS)gcc
AS	= $(CROSS)as
LD	= $(CROSS)ld
OBJCOPY = $(CROSS)objcopy

TARGET	= foo
BASE	= 0x04000000

CFLAGS	= -g -Os -fno-strict-aliasing -fno-common
-ffixed-r8 -msoft-float -D__KERNEL__ -fno-builtin
-ffreestanding -nostdinc -isystem
/usr/local/arm/3.4.3/bin/../lib/gcc/arm-non-linux-gnueabi/3.4.3/include
-pipe -DCONFIG_ARM -D__ARM__ -march=armv4 -Wall
-Wstrict-prototypes

INCLUDE =
-I/home/shaks/docs/monitor/u-boot/u-boot-1.1.2/include
-I/usr/local/arm/3.4.3/lib/gcc/arm-none-linux-gnueabi/3.4.3/include

LIBSTUBS =
/home/shaks/docs/monitor/u-boot/u-boot-1.1.2/examples/libstubs.a
LGCC 	 =
-L/usr/local/arm/3.4.3/bin/../lib/gcc/arm-none-linux-gnueabi/3.4.3
-lgcc
-L/home/shaks/docs/monitor/u-boot/u-boot-1.1.2/examples
-lstubs

LIBSTUB_INCLUDE	=
/usr/local/arm/3.4.3/bin/../lib/gcc/arm-none-linux-gnueabi/3.4.3/include
LDFLAGS	= -g -Ttext $(BASE) -e main 

all:
	$(CC) $(CFLAGS) $(INCLUDE) -c $(TARGET).c -o
$(TARGET).o
	$(LD) $(INCLUDE) $(LDFLAGS) $(TARGET).o -o $(TARGET)
$(LIBSTUBS) $(LGCC)
	$(OBJCOPY) -O binary $(TARGET) $(TARGET).bin
2>/dev/null

clean:
	rm -f *~ *.o *.bin $(TARGET)

Voila! Voila!
