Re: More newlib issues w/StrongARM Target

[David J Croyle <dcroyle at telerama dot com>]

Hello again.

After having rebuilt Binutils & EGCS with the same configuration
(--target=arm-elf & using the newlib headers & not specifying a host),
we then successfully built NewLib for an ARM target. Following the
newlib build we tried to compile a sample "helloworld" program and
encountered some road-blocks.

We wrote a simple Makefile to help automate the test builds; the
contents
of the Makefile and errors are listed below.

Any suggestions? 

Thanks,
Dave Croyle & Vasant Ram.

P.S.
We will not be using Angel as our debugger, do we need to modify the
newlib compile such that it does not issue -DARM-RDI-ANGEL?


Makefile:
CFLAGS = -g -Wall -Wa,-a=$*.lst

testprogram:  	helloworld.o
		arm-elf-gcc $(CFLAGS) -otestprogram helloworld.o \
		-Wl,-Map=testprogram.map --cref \ 
		-L/usr/local/home/vram/strongarm_embedded/newlib_test \ 				
-nostartfiles -nodefaultlibs -nostdlib -lc -nostartfiles

helloworld.o	:   helloworld.c
			arm-elf-gcc $(CFLAGS) -c -O helloworld.c


clean:	
	rm -f helloworld.o testprogram.o *.lst *.map
	rm -f testprogram


When we issue "make" we get the following errors:
