Dear Zhuang, In the command cmake -DDEAL_II_DIR=/path/to/installed/deal.II . "/path/to/installed/deal.II" is the path you have installed dealii into, you need to change it to the path you actually installed in. In your above comment cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/dir ../dealii-9.1.1 if you donot change the "-DCMAKE_INSTALL_PREFIX=/path/to/install/dir" to any other path, you may need to change the DEAL_II_DIR: cmake -DDEAL_II_DIR=/path/to/install/dir . , and you change the dealii version in the CMakelist.txt in step-1 directly, then it will use the dealii-9.0 to configure. You may have installed the dealii-9.0.0 before and the PATH DEAL_II_DIR may link to dealii-9.0. And step-1 donot need mpi.h, it maybe just is a fake hints in VScode, and if you want VScode to know your code and give code complement&highlight then you should add the include path to VScode.That is another question, you may need the VScode extension "ms-vscode.cpptools " to complement code and highlight.
