Hei all I used Microsoft Visual Stud . Run Petsc in this platform and got the following error:

Now I want to solve the PDE using GMRES. In addition, I do have the matrix A, but I have a function which computes Ax, so I also need to use the matrix free method. I am very new to PETSc, so I am looking for examples on solving linear systems using GMRES and/or matrix-free method.
