Request for OpenGL ES 3 Support on Linux

[shb3014]

I recently discovered this project and am very intrigued by the concept. I’m currently developing a desktop ARM Linux robot and would love to implement Rive natively, rather than relying on a web framework, in order to showcase smooth animations. However, the SoC in use supports only OpenGL ES (Vulkan is also supported, but I haven’t managed to get it working yet). Would it be possible to add support for OpenGL ES 3 on Linux as well?

I can see what i can do, but we have to check if rive supports gles3 on desktop (it might require Angle?)

Have you tried adding JUCE_LINUX here ?

Thank you for the prompt response! I apologize for the lack of clarity in my request. What I meant is that I'm developing a robot that sits on a physical desktop (a companion robot with a screen) and interacts with users, not a Linux desktop. To achieve this, I plan to use a headless Debian system with a compositor like Weston or Sway to launch the application.

You mean that by adding the macro, I could potentially get a working version that uses gles2 on Linux? I'll give it a try!

I built example_render with JUCE_LINUX added. But I got Segmentation fault when running it. The full log:

You need to launch it with a debugger to see where it crashed, without at least a stacktrace we cannot point ourselves in the right track

@shb3014 are you able to provide more information on where it crashes ?
