How to include CERN root directory in c_cpp_properties.json of Visual Studio Code running in Ubuntu?

[pietrocaradonna]

I have recently installed Visual Studio on Ubuntu to help me with writing Geant4 code, and it’s awesome. However try as I may I can not find a way to include the CERN Root directories into c_cpp_properties.json so that I can develop Root scripts in Visual Studio in order that I can process my simulated data.

CERN Root is working on my computer using my Sublime text editor. I have tried to locate the CERN Root header files but I can’t seem to find them as easily as I did for Geant4, and I don’t understand why?

Below is my c_cpp_properties.json script. For what it’s worth, I would appreciated immensely if someone could help me understand how to include CERN Root directories into c_cpp_properties.json so that I can write Root scripts in Visual Studio.

Thank you for your time

Peter

Hi Pietro,
and welcome to the ROOT forum!

When you say Visual Studio you mean Visual Studio Code I guess, since you are on Ubuntu?

I am not familiar with the json config files in VS Code, but for example root-config --cflags prints compilation flags that also include the location of ROOT’s header files. In most cases it will be ${ROOTSYS}/include, but it depends on the installation method of course.

I hope this helps!

Dear Enrico,
Thank you for your warm welcome.
Yes: I do mean Visual studio code! And thank you for your suggestion to use root-config --cflags. That’s exactly what I needed to find out in which directory my ROOT files are in. For me, I include the following into my c_cpp_properties.json and it works just fine

    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "${ROOTSYS}/include",
                "${G4INCLUDES}/**",
                "/home/compton/Downloads/build-root/include",
                "/home/compton/Documents/geant4.10.05.p01/examples/Projects/1-POLARIZATION/Pol01a/include",
                "/home/compton/Documents/geant4.10.05.p01/examples/Projects/1-POLARIZATION/Pol01a/src",
                "/home/compton/Documents/geant4.10.05.p01/source/run/include"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "gnu18",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}

Thanks you very much for your help.
Best

Alright, glad it works! I updated the title to avoid confusion between Visual Studio and VS code
