The Max 8.2 SDK: An Overview

Thanks for this! :-)

Hi,

i typed in my terminal git clone git@github.com:Cycling74/max-sdk.git as in the video. It answers The authenticity of host 'github.com (140.82.121.4)' can't be established. ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU. This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'github.com' (ED25519) to the list of known hosts. git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

What has happened? Thank you Thomas

I had the same problem. I had to follow some steps to create a key on my machine. You need a github account. Gooogle "git@github.com: Permission denied (publickey)" or use docs at github. If you can't get it done, you could always download manually from github (don't forget the max-sdk-base). More important is to have homebrew / cmake accessible in your terminal.

Hi Thomas,

Looks like the difference between cloning via SSH vs HTTPS is causing the error. The quick solution would be to instead use git clone https://github.com/Cycling74/max-sdk.git --recursive

(That --recursive flag will pull in the max-sdk-base submodule you'll need as well in one go.) For more info: With git clone git@github.com:Cycling74/max-sdk.git, git will use ssh to pull in the repository to your local machine. This means you'll need to have SSH keys added to your GitHub account. Instructions here: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account

if you are having trouble cloning from github, you can simply download the latest release here - https://github.com/Cycling74/max-sdk/releases/latest

Thanks a lot! Now it works...

Can anyone comment on whether you need an apple-silicon machine in order to make an apple-silicon-native external? Or can it be created on an older Intel machine, but still work natively on an AS machine? Thank you!

You don't need an Apple Silicon machine to make an M1 native external as long as you have a recent version of Xcode.

Requirements, to be precise, are: Xcode >=12 and MacOS >= 10.15 (Catalina)

Do the changes in the 8.2 SDK also explain why externals compiled in previous versions don't work in Max 8.2 onwards? I have an external that was working fine in 8.1 and the moment I updated to 8.2 it stopped working.

I'm trying to determine whether I need to re-compile this external with the 8.2 SDK in order to continue using it in Max 8.2 (even if I'm still on Catalina or Big Sur) ?

For context, it's the old Fingerpinger external for use with the Apple trackpad and it makes use of the Apple MultitouchSupport.framework (/System/Library/PrivateFrameworks/MultitouchSupport.framework/)

a (very) basic raw question: can we play with Live API through 8.2 SDK for externals running in M4L devices ??

Trying to follow the video letter by letter. I get stuck @ cmake --help: zsh: command not found: cmake searched, but brew install cmake does not work... (homebrew-core is a shallow clone.) Then I downloaded cmake.dmg, and followed the PATH instruction which leads to this error: CMake Error: The source directory "/Users/st/max-sdk/build/help" does not exist. Specify --help for usage, or press the help button on the CMake GUI. This is 100% confusing. Those error messages are helpful for those who know what it means, but they most likely don't run into errors anyway... I would love to help somebody to make tutorials for those who know nothing. My experience is always, that it looks so nice in the video, and fails on my system. And nobody anticipated what could go wrong... I would also prefer always methods without the command line. Nothing against it in general, but for me I know better what is going on if I just copy folders and files instead of doing such things in the terminal with about 1000 keystrokes more and not really knowing what is going on... There should be either droplets or little apps to just do all these commands. Why typing all those letters, if a program could type it for everybody? Sometimes I think professional programmers are not lazy enough...

+1, even with CMake installed via homebrew, i then attempt the 'cmake -G Xcode ..' part and get this:

sorry for being so stupid and incapable of 'modernization', Cycling74 (wasted 4 hours this morning googling everything i could with no luck #FML 😔🔫)

@RAJA TRA I remember seeing the same error. Iirc I could solve it with the xcode -select command at the bottom of this thread

@11OLSEN oooof! can't thank you enough!! THANK YOU THANK YOU THANK YOU!!!! It works now! 😭 i've never been more relieved that Cycling74 won't be able to leave me behind in their fast moving dust

(i would like to add, tho, they should show more 'empathy' for their user-base when creating documentation and tutorials, 'empathy' is required for proper 'modernization' of the human spirit 🥸)

ok, i'm happier now. i'll leave it at that. Thanks again, @11OLSEN 🙏

@Tj Shredder It is not easy to make a failsafe tutorials, but i totally understand you as I also had to solve multiple problems before it finally worked. I documented everything in a comment on Isabels yt vid but for some reason the comment was deleted. You should focus on a proper homebrew (+cmake) installation first.
