Hi Martin, Sorry for the slow response - I have been on vacation.
If you save a source file with a new name then you will need to update your CMakeLists.txt file - it doesn't know what you intend to do with the new file. I recommend reading through https://www.dealii.org/developer/users/cmake_user.html to better understand how to set up your own project with CMake. If you have the virtual machine then it is easiest to just install either eclipse or QT creator inside the VM itself with the "apt-get install" command.

I suppose below procedure should work: 1 Open Deal.II example, the cpp file, with text editor 2 make changes to it, and save it as another cpp file 3 Use cMake to run this new cpp file at the command line 4 if no mistake, the new cpp file will run am I correct? Last, where should I install the IDE? I am using virtual box machine with deal.II package in a window system. can I install Eclipse in Virtual box machine? it has Ubuntu system in the virtual box.

You CAN use plain text editors and run CMake from the command line (in fact, with many tools you will end up still running CMake from a window inside them) but its usually better to use something more sophisticated (like an IDE that can run a debugger). If you look on the wiki we have instructions for both Eclipse and QT creator: https://github.com/dealii/dealii/wiki a lot of people use VS code - we don't have instructions for it, and I don't use it, but since we use CMake it shouldn't be that hard to point VS code at your build directory and have it extract some information. If anyone actually uses VS code I would appreciate if they could weigh in here!

I installed virtual machine with Deal.II, and run step 7 on terminal without any problem. The question is if I want to compile bigger program with Deal.II , what is the typical working environment? I assume we can not with terminal for such a purpose. I saw people using Nano to run Deal.II, but want to ask the standard tool for such process. Emacs or Vscode? Do I need to connect them to Deal.II? I am very new, and this could be a quite silly question.
