[En-Nut-Discussion] Newbie - Debugging - makefile removes(rm) *.elf file

[Anton Veldhuizen]

Thanks Marc,

My elf file problem is now sorted.  Now trying to convert that to a coff...  
My makefile instruction is as follow:
coff: $(OBJS) $(PROJ).elf $(PROJ).cof end

The compiler output:

make: *** [gsmgenie.cof] Error 255

My c compiler flags:
CPFLAGS = -g $(MCFLAGS) -Os -Wall -Werror -Wstrict-prototypes 
-Wa,-ahlms=$(<:.c=.lst) $(DEFS)

My assembler flags:
ASFLAGS = $(MCFLAGS) -Wa,-amhls=$(<:.S=.lst),-gstabs $(DEFS)

Question:
How does one generate the .STAB section?  I've added the -g and -gstabs to 
the above CPFLAGS and ASFLAGS respectively.

Kind Regards,
Anton

Thats done automagically, because make sees that noone uses the generated
elf-file IMHO.

If you add the elf.file to your build rule or e.g. just type
'make projektname.elf' it will be generated.
