    No, I’ve left the glDeleteShader() calls commented out. It runs fine on OpenGL; I would imagine if a shader program is deleted unexpectedly, it would also crash if I’m not using MetalGL?

    Hi Bill, yes I’ve upgraded to the latest MetalGL. It never drew before, but now it draws for a little while.

    Nothing appears in the logs, and location value 0 should be ok. I will investigate further. In another render task, it often crashes after about 10 seconds with this error:

    [***MetalGL ERROR***] GL_INVALID_VALUE. glDrawArrays(): Shader program 2 does not exist

    Do you know what this means?

    Hi Bill,

    Things are looking great! However, one issue has come up – after drawing one frame, I have a call to glUniformMatrix4fv:

    glUniformMatrix4fv( location, count, GL_FALSE, ( m_bufferData ) );

    values are:

    location: 0
    count: 2
    m_bufferData: -1.509

    The call to “mglUniformMatrix4fv()” results in a crash: EXC_BAD_ACCESS (code=1, address=0x1475c310). Does that mean anything to you?

    Hi Bill,

    I do have an iOS 8 device, and I still couldn’t get it to work. I have the following error when running Apple’s sample code:

    Hi Bill,

    I’m running it through Xcode’s debugger, and I found that the error is actually the same as the Apple Sample code thread:

    [mgl-info] Changed size of renderbuffer 1 to (1407, 1536)
    /BuildRoot/Library/Caches/com.apple.xbs/Sources/Metal/Metal-54.30/Framework/MTLRenderPipeline.mm:1061: failed assertion 'No valid pixelFormats set.'

    The stack is:

    Hi Bill,

    I commented glDeleteShader() out, but got the following error:

    /BuildRoot/Library/Caches/com.apple.xbs/Sources/Metal/Metal-54.30/Framework/MTLRenderPipeline.mm:1061: failed assertion 'No valid pixelFormats set.'

    Hi Bill,

    Thanks for following up – unfortunately I’m working with proprietary and licenced source code with my test app and I’m unable to freely release the project source code.

    That fixed it! I missed a project. Thank you!

    However, I seem to have a new problem: the app crashes with the following stack:

    You’re right: GetSystemContext() only returns an instance of EAGLContext. Any chance you might know if I missed a step setting this up?

    Thank you for your replies!

    Hi Bill,

    I’m not seeing any error message in the console logs. This is the function call that I have, and as you can see from the above, layer is CAMetalLayer:

    [GetSystemContext() renderbufferStorage: GL_RENDERBUFFER fromDrawable: layer];

    If I’m not using MetalGL, then this doesn’t occur.

    Thanks!

    Thanks for your reply, Bill. My this is my view:

    m_view
    <EAGLView: 0x145e79170; frame = (0 0; 703.5 768); autoresize = W+H; layer = <CAMetalLayer: 0x145e798f0>>
    

    Seems like it has a CAMetalLayer.
