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

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.
