Hi Aram,
i am using the arm-elf-gcc compiler to generate the assembly code
arm-elf-gcc -mthumb -S new.c
after this i use the arm-elf-as for genrating machine code
arm-elf-as new.s
Note - these two steps could be combined into one by using the -c switch instead of the -S switch:
arm-elf-gcc -mthumb -c new.c
it produces one a.out file..
Note: Despite its name this "a.out" file is not an executable program it is just an object file that still needs to be linked. Naming the file a.out is a "feature" of the assembler.
arm-elf-ld a.out
produces error like
arm-elf-ld: warning: cannot find entry symbol _start; not setting start address
how do i type the correct command line option for this
Try using gcc to control the entire process from compilation to final link, like this:
arm-elf-gcc new.c
Cheers Nick
