[petsc-users] Question on re-coding ex29

[Alan Wei]

Dear Sir/Madam,
    I hope you're having a nice day.
    I asked several questions about src/ksp/ksp/example/tutorial/ex29.c
before, and learned some beginning staff of PETSc. Right now, I want to
start to use it to my own program. Firstly, I want to isolate the ComputeRHS
function in ex29, which means I want to put ComputeRHS to another c program
file. I did that; however, some problem pop up when I compile it.

The program and modified makefile are attached. Could you please take a look
and give me some suggestions.

best,
