Hi Everybody,
I have configured gcc-2.95.2 on CYGWIN(WIN-NT Machine).
My aim is to link few object files (create Load/Exe Image) using my "linker
script". I am specifying < start address = 0x100000> in the section command
as shown:
SECTION
{
	.text 0x100000
	{....
	}
...
}
The program doesn't executes, it says permission denied.
Even if I remove "__image_base__ + __section_alignment__", the program
doesn't executes, it says permission denied.

The program only executes when I specify:
SECTION
{
	.text __image_base__ + __section_alignment__ :
	{
	....
	}
}
which is in the default linker script of CYGWIN.

The same is the case with ALIGN command.
It takes ALIGN only as "ALIGN(__section_alignment__)". If I give some value
for ALIGN the program doesn't executes, It says permission denied. Even if I
remove "ALIGN(__section_alignment__)", the program doesn't executes, it says
permission denied.

QUERY:
My question is how should I specify a different start address than the
default one(__image_base__ + __section_alignment__).
and different value of ALIGN(xxx).

Thanks,
Manoj

Manoj,

You can see how you have built in the file 'config.status' (of your 3 build-
directories, being binutils-xxxx, gcc-yyyy and newlib-zzzz however you've
called them), if you have any doubt ...

Regards,

Philippe Bertin.
