How to Create New Files in C++ with CLion?

To clarify, when you mention executables, are you trying to create one program from two files or are you trying to create two distinct programs? You will generally need to have both a .cpp file for the implementation and a .h file for declarations. Make sure both files are included in your CMakeLists.txt, as that tells the build system what to compile together.

It sounds like you want to add a new source file to an existing executable. In CMake, you typically have to specify which files should be included in your build by editing the CMakeLists.txt. Just find your existing source files listed there and add your new .cpp file to the list. If you've created the file through the IDE tools and it still doesn't work, maybe it didn’t get linked properly during the project setup.

It can be a bit tricky when you're new to CMake and project structures. If you're facing issues with creating a new C++ file, try sticking to this format: n1. Describe what action you took (e.g., selecting 'New File' in CLion). n2. Explain what you expected to happen. n3. Share the error message you encountered. Providing this information can help others assist you better!

Just to note, if you ever see an error message when trying to create new C++ files, try to read it carefully. Executables are compiled files, so they're separate from your source code files. If you're having issues with files not appearing after creation, make sure they’re correctly listed in your CMakeLists.txt and get appropriately compiled during the build.

You might want to clarify what exact steps lead to the error message. An executable is essentially a program that you run, so knowing whether you intend to create new functionalities for an existing program or set up a totally new one will help focus the advice. Any screenshots or detailed descriptions can really help you get the right support!
