Dear Ian & Ralf,

	First of all thanks for all your responses to mails.

I got the most recent binutils compiled and running here on my MIPS System. 
As again I took the famous "hello world" test program compiled it to test 
the linker. I got the error....

dynamic linker: ./test: unidentifiable procedure reference (address = 
0x40062cd8) Killed

Then after trying to trace at the system call level using the truss utility 
that I have , I added an explicit _exit(0) in the test program and compiled 
it.

To my big surprise program executed normally Which meant that the linker did 
not get killed. For the first time I could see the linker produce output on 
my system.

test.c
******
main()
{
	printf("Hello World !!\n");
	_exit(0);
}

gcc -v test.c -o test

Hello World !!


Could there be any problem with the start up files that are being used ???.

I would be happy If you could provide me with any comments of your's.

Thanks again in advance. 

With best regards

Koundinya



P.S: 
	I think i am Missing out one some of the discussion that went on ...I have

Has this mail been posted to the gas2 or bfd lists. Or is it between You 
people.. I did not receive any mails regarding this discussion . You could 
probably forward those mails to me if you don't mind.
