Qt Creator as IDE for closed source?



  • Hello,

    I'm between CLion, which I had been using for years now, and Qt Creator as an IDE for C/C++ closed source projects.

    Qt Creator seems to be alright after testing it, and I want to make sure I'm not infringing any TOS.

    I want to use its IDE capabilities with CMake builds, and with zero QT Libs' dependencies, so I don't need to use any of the Qt technologies provided by the company, thus I want to know:

    1- Can I use it this way without the need to open source my commercial code?
    2- Am I still obliged to mention Qt, even though I'm only using the Creator IDE?

    Thanks for sharing your insight here, I really need to know how to handle this, or whether I should stick to CLion.

    1 - yes, QtCreator license doesn't matter as long as you don't incorporate QtCreator code into your projects
    2 - no

    Think about GCC which is GPL licensed - if you use it you do not have to open source your app and you do not have to mention it.



  • Thanks @jsulm ! Precise and concise.

    Have a great day.
