I am new to PETSC and have exercised on a few simple programs to get myself familiar with PETSC and the simple codes work properly. So the environment for PETSC is set up with no problem. Now I am trying to do some work in my big code which is written in C++.
Somehow, I get the compile error for "CHKERRQ", and the error message is:</div>

Basically, it complains about "CHKERRQ", if I remove "CHKERRQ", the code compiles with no problem. Could someone please shine some light on this?</div>
