chuck-max: a Max/MSP external with an embedded chuck engine

Hi Lukas,

Can you please provide some more information so I can help. What machine did you try to run it on? Did you compile the external yourself? It can currently only run on macOS x86_64 or arm64 since I'm not so well versed on windows dev.

If you are on a Mac it should be architecture independent if you build it yourself... here's the relevant part of the CMakeLists.txt file:

if (APPLE)
    if (${CMAKE_GENERATOR} MATCHES "Xcode")
            if (${XCODE_VERSION} VERSION_LESS 10)
                message(STATUS "Xcode 10 or higher is required. Please install from the Mac App Store.")
                return ()
            endif ()
    endif ()

    if (NOT CMAKE_OSX_ARCHITECTURES)
        if(C74_BUILD_FAT)
            set(CMAKE_OSX_ARCHITECTURES "x86_64;arm64" CACHE STRING "macOS architecture" FORCE)
        else()
            set(CMAKE_OSX_ARCHITECTURES ${CMAKE_SYSTEM_PROCESSOR} CACHE STRING "macOS architecture" FORCE)
        endif()
        message("CMAKE_OSX_ARCHITECTURES set to ${CMAKE_OSX_ARCHITECTURES}")
    endif()
endif()

This means that it defaults to a native architecture of the Mac that it's compiled on. It also means that if it's built on a different Mac with a different architecture than the one you try to run it on, it will give you an 'incorrect architecture' error.

This may be the problem you have... Note that you can build the external for both macOS architectures ("universal") by setting the cmake C74_BUILD_FAT option as follows:

mkdir -p build && cd build && cmake -GXcode -DC74_BUILD_FAT=ON .. && cmake --build . --config 'Release'

Or just

make universal (I just added this option to the main branch)

Let me know how it goes.. Also note that it may be better to post your issue to the project issue-tracker: https://github.com/shakfu/chuck-max/issues
