When I try to compile the tutorial code of tutorial http://doc.nektar.info/tutorials/latest/fundamentals/differentiation/fundamentals-differentiation.pdf , I follow the instruction of task 1.1: I first use cmake command to generate makefile and then type 'make' but the terminal give me error messages like this:(I can successfully run tutorial code in http://doc.nektar.info/tutorials/latest/fundamentals/integration/fundamentals-integration.pdf, but I can't compile the code of this one). What should I do?
