You are trying to pass to the Windows compiler Linux style command line options
which the compiler cannot understand. You need to look at the windows compiler

Hello
I am trying to solve system of equations using time stepping. I use
TSSetIFunction() to define the DAEs. I tried to add the xdot[] term to all
of variables. As a solution algorithm , I solved with newton line search
with ASM as a preconditioner. In the case, I want to add the xdot[] term to
