CLion cannot detect classes from sources, and does not have intellisense / code completion

Question

I'm using CLion so I can (hopefully) have the ability to:

• Have code completion for a file type that is registered as a c++ file (In my case the file type is called .hps)
• Make full use of the error hightailing features and all of the intellisense on my .hps files
• Be able to use classes from other hps files, located in different folders in my project.

The general c++ style coloring is working, however, CLion won't notify me about syntax errors inside hps files:

• CLion won't find the source files I include, and therefore won't detect any classes that are declared inside other hps files and their methods (all of the folders that include that hps files are located inside a folder named "script"

Implementation of what I'm trying to include:

And as you can see, it does not detect it:

Now, this is the setup of my project:

1. My project is located and opened at folder that has a folder inside it called "script" in which all of the .hps files I include are there.

2. I've set a CMakeLists.txt file that runs on MinGW environment. This is the full content of that file:

   

3. There is a file, in my PARENT folder, called hps_api.hps, that consists classes declarations as well. Note that CLion won't detect it as well. Did I do something wrong? The only thing I pretty much did was to add include directories to the cmake file, but I guess it's not enough?

In another program called CodeLite for example, it's possible to just add to a list a path to search files to include, and then CodeLite parses those files and I can go to declarations of classes without any problems. Surely it's possible with CLion as well, right?

Answer 1

Syntax Errors

Is it possible that you have Power Save Mode activated from the File menu? If it is activated, some code-parsing features may be disabled.

File Type .hps

I am guessing you already have the file type .hps registered as a C/C++ file in Settings -> Editor -> File Types . If not, you should register it!

CMakeLists

You might need to configure some more properties like the project name and a target to associate the project with the files you are using.

cmake_minimum_required(VERSION 3.12)
project(YourProjectName VERSION 0.1.0)

include_directories(script/agents)
include_directories(script/areas)
include_directories(script/base)

add_executable(YourProjectName main.cpp header1.hpp source1.cpp path/to/header2.hpp path/to/source2.cpp)

If you are not building an executable, but a library, you might need to use add_library instead. For the syntax you can check the documentation .

I hope this helps!
