SDL.SDL_Init does not work on Jetson Nano

[peltiern]

Hello,

I use Jamepad (and therefore SDL) to control a robot with a Logitech F710 gamepad. I have no problem when using it on a normal PC running Ubuntu 22.04.2. Same on a Raspberry Pi 4. But it doesn't work on a Jetson Nano (Ubuntu 18.04 ARMV8). Code stops in class Jamepad.ControllerManager.nativeInitSDLGamepad(l. 99) on

if (SDL.SDL_Init(SDL.SDL_INIT_EVENTS | SDL.SDL_INIT_JOYSTICK | SDL.SDL_INIT_GAMECONTROLLER) != 0){
    return false;
}

There are no errors. The code just doesn't move forward anymore, as if it falls into an infinite loop.

If the native code was not found (SDL library), I think there would have been an error.

Do you have any idea of ​​the problem ?

Thanks,

Nicolas

Hello,

Do I need to generate the libsdl2gdx64.so file on the Jetson Nano? And how ? In the project, I see the NativesBuild.java class. Is this it?

I'm having the same problem, you can try to compile by following the steps in BUILDING.md but when building natives for linux it does not have a build-linux.xml for arm just x86 and then it gives me an error because I have g++ arm that compiles arm code because I'm trying to do this on an arm device (I'm trying to get a minecraft mod to work on a nintendo switch (arm device running kubuntu) and that mod uses sdl2gdx, the mod does have a libsdl2gdx64.so but it is for x86) and this is the error that I got:

Executing 'ant -f /home/red/Desktop/sdl2gdx/jni/build-linux64.xml -Dhas-compiler=true -Drelease=true clean postcompile'
Buildfile: /home/red/Desktop/sdl2gdx/jni/build-linux64.xml

clean:

precompile:

create-build-dir:
     [copy] Copying 2 files to /home/red/Desktop/sdl2gdx/jni/build/tmp/linux64

compile:
    [apply] g++: error: unrecognized command-line option ‘-mfpmath=sse’
    [apply] g++: error: unrecognized command-line option ‘-msse’
    [apply] g++: error: unrecognized command-line option ‘-m64’

BUILD FAILED
/home/red/Desktop/sdl2gdx/jni/build-linux64.xml:108: apply returned: 1

I think it is because those paramters for g++ are only available on x86 and that build-linux64.xml only knows how to compile for x86. Please help
