Details:

Dear Sirs,

I am trying to use a Makefile to produce code for the Blackfin processor.  My
development system uses Suse 10.1.

I have written a "Hello World" c program and a simple Makefile:

hello : hello.o
       cc -o hello.c hello.o

hello.o : hello.c
       cc -c hello.c

clean :
       rm hello hello.o

The default 386 gcc compiler has the path: usr/bin/ and the Blackfin compiler
the path: /opt/uClinux/bfin-uclinux/bin/.

When I type "make", the 386 gcc compiler is always used.

I have tried adding: CC = bfin-uclinux-gcc as the first line of the Makefile,
also: override CC = bfin-uclinux-gcc.  None worked.

The Blackfin compiler path is "visible" as:
 bfin-uclinux-gcc -Wl,-elf2flt hello.c -o hello works.

I have experimented and checked the web with no success.

Can you please tell me how "make" can be forced to use the Blackfin compiler
rather than the 386 compiler?

Best wishes,

Peter
