Re: Gcc driver and -T option

Thanks for replying.  Here is some relevant  part from the linker script that is linked explicitly.
Basically I'm creating the overlay of data and rodata from 1.o and 2.o 
If I don't include 1.o 2.o , how should I achieve this overlay ?
Any idea ?

 OVERLAY :
  {
    .program0_pd_data
    { 
        __program0_data_start = .;
       1.o (.data)
       1.o (.rodata)
       . = ALIGN(32 / 8);
        __program0_bss_start = .;
       1.o (.bss)
       . = ALIGN(32 / 8);
        __program0_bss_end = .;
    }
    .program1_pd_data
    { 
        __program1_data_start = .;
       2.o (.data)
       2.o (.rodata)
       . = ALIGN(32 / 8);
        __program1_bss_start = .;
       2.o (.bss)
       . = ALIGN(32 / 8);
        __program1_bss_end = .;
    }
  }
There could be other situations where one needs to specify the object files in the linker script. If that is the case , then shouldn't driver detect 
explict usage of linker script and hence generate .o s in the current directory ?

Thanks in advace,
