    i installed fresh felgo yesterday on a mac and tried a new project to compile to android with cmake.

    it does not work, i cannot select android or ios.

    please help



    what is this replacement for “Android” or replacement for IOS ?

    when i select replacement for android, i get “No CMake configuration found!”

    hwat should i do to make this work?

    Hi Bas,

    the replacement kits are mechanism of Qt Creator to re-create older kits that are no longer installed but still used by projects, to be able to keep building those. You can ignore them, to my experience, QtC is a little inconsistent here. For the new installation, you will need a proper new kit, not such a replacement one.

    In general, after installing Felgo 4, you need to set up your Android toolchain (it is recommended to use wizard in Qt Creator for this, in Preferences -> Devices -> Android). You can also find the guide and recommended versions in our docs: https://felgo.com/doc/felgo-deployment-android/

    Then you need to add the Felgo Android package via the maintenance tool.

    After that, you should have a proper Android kit set up to select and build in Qt Creator.




    Hello Alex,


    I am having similar trouble as Jack with an error saying “No CMake configuration found”

    In your answer to Jack, you mentioned “setting up a android toolchain file. How exactly do you do this? In my terminal I get the error “Fail to find toolchain file” fpund in CMakeDetermineSystem.txt

    How do I fix this error so I can build my app for android??


    Thank you for your help

    Please make sure to install all tools with the correct versions as described in the android deployment guide:

    If all is installed and set up correctly, there should be no warnings or errors shown when opening Options -> Devices -> Android in Qt Creator. If it looks okay, please try to build a simple Fego playground app project to verify it works.



    Yes! it works, thank you


    For anyone who may have the same problem with running Felgo 4 for android;

    – You need an NDK compatible with Felgo, as of the time of writting it is NDK 23c

    – You can use the jbr from Android studio for Java
