Error: SDL/SDL_gamecontroller.h: No such file or directory #include <SDL/SDL_gamecontroller.h>

collected Urho3D-1.8-ALPHA (everything is assembled)

decided to collect the simplest example from Urho3D

But for some reason, it writes a file that is not even in the project (protected internal) that there is no header SDL_gamecontroller.h, while it is not there such a file is in SDL2 / SDL_gamecontroller.h BUT I don’t want to fix the internal system files

I can’t understand how he (cmake) was able to collect all the examples, but I can’t cope (I connected all the libraries), here is a localized error:

You did not set up the include paths correctly in your project I’m pretty sure. I would very much recommend just using CMake for the project, as Qt Creator supports it and then you don’t run into these sorts of issues. That said, if you want to continue not using CMake I would recommend using it once for a build, and doing a VERBOSE=1 build with make so it shows the actual commands used to compile the samples, and then you can copy the necessary defines and include paths from that.

@SirNate0 but how should CMake look like for the simplest example (“hello world”) ???

It’s just that I’m not a hacker and it’s hard for me to work with complex systems (CMake)

Here’s the project template I’ve made, and below I’ll go through how to get it set up.

  1. Download the project (either clone or download a zip and extract it somewhere)

  2. Delete or rename the build directory. The CMakeCache.txt in it will point to a different path, and it’s not worth editing that instead of just starting from scratch.

  3. Call the script to generate the new build folder (I’m sticking with “build” as the name)
    ./script/cmake_generic.sh build

  4. You should see an error in the output telling you that it couldn’t find the Urho3D library.

    ...
    CMake Error at CMake/Modules/FindUrho3D.cmake:330 (message):
      Could NOT find compatible Urho3D library in Urho3D SDK installation or
      build tree or in Android library.  Use URHO3D_HOME environment variable or
      build option to specify the location of the non-default SDK installation or
      build tree.
    Call Stack (most recent call first):
      CMake/Modules/UrhoCommon.cmake:244 (find_package)
      CMakeLists.txt:23 (include)
    
  5. To fix the error, you need to specify where your Urho3D build is (the 1.8-ALPHA you downloaded, in your case). I’m not sure about how the directories are structured for the prebuilt packages, but for me this can be done by changing the call to:

    URHO3D_HOME=~/Projects/Urho3D/Build ./script/cmake_generic.sh build
    
  6. If you selected the right directory for the last one, you should get a message like the following at the end of the CMake output:

    -- Found Urho3D: /home/nathan/Projects/Urho3D/Build/lib/libUrho3D.a (found version "1.8-ALPHA-486-g93dcb6959")
    -- Configuring done
    -- Generating done
    -- Build files have been written to: /home/nathan/Downloads/tmp/Urho-Project-Template-master/build
    
  7. Switch to the build directory. cd build/

  8. Call make

    Scanning dependencies of target projectExe
    [ 50%] Building CXX object CMakeFiles/projectExe.dir/MultipleViewports.cpp.o
    [100%] Linking CXX executable bin/projectExe
    [100%] Built target projectExe
    
  9. If that succeeds, you should be able to switch to the build/bin directory (cd bin) and run the build executable (./projectExe).

  10. If you have errors running it, you can try replacing the CoreData and Data directories with the ones from the Urho3D download you have, as sometimes the shaders/scripts change a little and become incompatible. I’m not sure which version this sample was from.

That should hopefully get you started. You can change the ProjectName in the CMakeLists.txt to what you want the project to be called in QtCreator, and you can change projectExe to what you want the executable to be called. Note also that some of the parts of the define_source_files call are unnecessary (there is no Editor directory in my template project, and I believe GLOB_CPP_PATTERNS already includes *.cpp and *.h).
