What are the sequence of steps required to create executable file 
from C source file using GNU Compilers.
What are the necessary options used for that 
What are the Sequence of steps required to create executable file 
form Assembly sourec file using GNU Compilers.

Iam not familiar with GCC environment.If somebody help it will take 
less time to test sample programs .

Here is a batch file for compiling and linking a simple program:

arm-elf-gcc -Tlpc2106-rom.ld -nostartfiles -Wl,-Map=led.map,--cref,-nostdlib
 -s -o led boot.s led.c
arm-elf-objcopy --output-target ihex led led.hex
arm-elf-objcopy --output-target binary led led.bin

Hi, Leon, I have downloaded the lpc2100_gcc.zip from yahoo group and
can't find the led.map, where can I find it? or
I should define it my own??

Thanks.

led.map is an output file, not an input file.  It is the map file from the 
link phase.

led.map is the linker map file, it is actually generated by
-Map=led.map, and isn't supplied.

Hi,

Is there a gcc option to specify no_current_dir for
the search (or include) path? Or at least something to
override the current path with a \ufffdIdir option?

It seems like the current path is searched 1st & then
the \ufffdIdir\ufffds. Is there an option to change the order,
search the \ufffdIdir\ufffds 1st & then the current dir or
completely knock the current dir???

Thanks,
-Mike.

Use include <filename> instead of include "filename".  That should 
work.  That's the general intent of the difference and it does for most 
compilers I've used but I haven't tried it.

Hi,

I have requirement in my project where I have to
specify an object file contained in a library file in
my linker script.

Something like this:

MySection 0x1000 :
{
      myobj.o of mylib.a (.bss, COMMON)
}

In ADS scatter map its enough to specify just the
object files name. And the linker would pull it from
the linked-in libraries. I tried the same with GCC
(with it,s linker script), something like this,

ZeroISection 0x1000 :
{
      myobj.o (.bss, COMMON)
}

Does not work. Even thought the linker was supplied
with mylib.a, which contains myobj.o; it still gives
errors \ufffdmyobj.o not found\ufffd.


Please help me with this.

Thanks a lot,
-Mike.
