Hi,

I found many examples can not excuted in apple M2,Is there some errors for m2 ?

I see you selected some examples twice and some examples seem to work fine judging just by the logs. Can you please separate them and show the ones that fail again.

As for this error:

error (invalid argument): in 'CreateResourceHeap': cannot create resource heap with empty list of heap bindings
cannot create resource heap without bindings in pipeline layout

This is a small mistake, I haven't updated the Compute Shader example in a while, but you can simply change this line:

LLGL::Parse("cbuffer(2):comp, rwbuffer(3):comp, rwbuffer(4):comp")

... to this:

LLGL::Parse("heap{cbuffer(2):comp, rwbuffer(3):comp, rwbuffer(4):comp}")

and it should fix it. For a ResourceHeap, the resource bindings need to be specified as heapBindings and the Parse function reads the above layout as regular bindings.

The GLSL errors ERROR: 0:2: '' : version '130' is not supported can probably be fixed by just raising the GLSL shader version to 410 (in the respective .vert and .frag files) which is the highest version available on macOS.

UPDATE: I fixed two of these issues with c24c33e and dd5bb47.

Most of the issues seem to be coming from lower multi-sampling support. I addressed that in b46428e.

As for example 16 (Resource Binding): This one requires GLSL 430 for the GL backend, which is not supported on macOS, so you'll have to stick with Metal for that example and the OpenGL support is fragile on macOS anyway as it has been deprecated a long time ago.

I can't tell why this error shows up, though:

in 'CreateRenderTarget': cannot use color format for depth-stencil attachment

The RenderTarget example should only create a custom depth texture with the D32Float format, which is not a color format, so I don't understand how this ends up with a wrong configuration. In case you are able to compile and run this example through Xcode, can you set a breakpoint at the LLGL_UNREACHABLE(); line in GLRenderTarget.cpp and tell me what value lldb shows you for the format parameter?

Besides that, I would stick to Metal over OpenGL on the modern M1 and M2 Macs.

Hello-Triangle still not work

After generating the Xcode project, when debugging, the paths for resources (such as "Example.metal") need to be redefined. Could you provide a command for this? My command is as follows:

#!/bin/sh

SOURCE_DIR="$(dirname $0)"
BUILD_DIR="$SOURCE_DIR/xcode_macos"

# Ensure we are inside the repository folder
if [ ! -f "$SOURCE_DIR/CMakeLists.txt" ]; then
    echo "error: file not found: CMakeLists.txt"
    exit 1
fi

# Make output build folder
if [ "$#" -eq 1 ]; then
    BUILD_DIR=$1
else
    if [ ! "$#" -eq 0 ]; then
        echo "error: too many arguemnts"
        echo "usage: BuildMacOS.command [BUILD_DIR]"
        exit 1
    fi
fi

if [ ! -d "$BUILD_DIR" ]; then
    mkdir "$BUILD_DIR"
fi

# Checkout external depenencies
GAUSSIAN_LIB_DIR="$BUILD_DIR/GaussianLib/include"

if [ ! -d "$GAUSSIAN_LIB_DIR" ]; then
    (cd "$BUILD_DIR" && git clone https://github.com/LukasBanana/GaussianLib.git)
fi

# Build into output directory
cmake -G "Xcode" \
    -DLLGL_BUILD_RENDERER_OPENGL=ON \
    -DLLGL_BUILD_RENDERER_METAL=ON \
    -DLLGL_BUILD_EXAMPLES=ON \
    -DGaussLib_INCLUDE_DIR:STRING="$GAUSSIAN_LIB_DIR" \
    -S "$SOURCE_DIR" \
    -B "$BUILD_DIR"

I haven't found a way in CMake yet to define the working directories. That's why I added this note to the examples folder. And the RunExamplesMacOS.command script automatically changes the working directory, but I don't know how to tell CMake to configure the projects this way.

The Hello Triangle tutorial doesn't use the ExampleBase project, so you'd have to change the sampling count to 4 yourself, that's what all Metal devices support. You can change it here: https://github.com/LukasBanana/LLGL/blob/95a613400fb7001306edbdb0c49cb32f8a284989/examples/Cpp/HelloTriangle/Example.cpp#L40

Thank you for your response. Placing all resources in a single directory instead of separate placements for each project, and then copying the resources during Xcode project generation, followed by concatenating the resource directory with their respective files, could be a potential solution. Due to this issue, many of my projects require manual modification of all paths for debugging. Unfortunately, I am unable to provide you with more debug information promptly at the moment. I will provide you with feedback as I continue to use it in subsequent processes. Once again, I appreciate your response.

by the way , "swapChainDesc.samples = 4 " is work for me.

[LukasBanana]

I found some CMake options to generate the working directory automatically:

• For Visual Studio: VS_DEBUGGER_WORKING_DIRECTORY
• For Xcode: XCODE_SCHEME_WORKING_DIRECTORY

I'll take a closer look tomorrow as this will require a higher CMake version as what I used before.

[LukasBanana]

I added the automatic generation of the working directories for VS and Xcode with 9561114.

Any updates on this issue @lemoon? I cannot test on an M2 device myself.

[LukasBanana]

Several issues in the Mac backend have been fixed in recent commits. Please feel free to open a new ticket if any of the mentioned issued persist.
