Problem with static and global data initialization

[Venkata, Bulusu (IE10)]

Hi,
   Thanks for the reply. I have my own startup which is linked with the
application and other necessary files(like the crt0.o). So I'm sure that the
necessary functions are called(I've even taken the objdump of the exe to see
the contents of the memory where the variable is defined and it is correct).
The weird thing is that the bss section initialization is working and data
section initialization isn't.

Thanks and Regards,
Sudhakar

   You're on the right track. Once you have provided and linked crt0.o,
   you'll need to ensure that it is called. Have you provided the label
   _start for the standard startup to call? I'm just going on the
   following in the GCC Manual:

>>>
-nostartfiles
   Do not use the standard system startup files when linking. (e.g. crt0.o,
with
   _start) The standard system libraries are used normally, unless -nostdlib
or
   -nodefaultlibs is used.

   There has to be better documentation somewhere, but I gave up
   googling before finding it.
