如何在 M1 mac 上使用 c++ 运行 mediapipe

Question

environment

Macbook air M1 2020.
Big Sur 11.3.1.

What I wanna do

I want to succeed to run "mediapipe c++ hello_world" below. https://google.github.io/mediapipe/getting_started/install.html#installing-on-macos

I tried the following tries and failed.

try1

do

Just follow the guideline
https://google.github.io/mediapipe/getting_started/install.html#installing-on-macos

• 4.Install OpenCV and FFmpeg. => I used option1.

bug

In lesson 6, I faced a bug below.

// run lesson 6
mediapipe % bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world
2021/05/23 21:06:14 Downloading https://releases.bazel.build/3.7.2/release/bazel-3.7.2-darwin-arm64...
2021/05/23 21:06:16 could not download Bazel: HTTP GET https://releases.bazel.build/3.7.2/release/bazel-3.7.2-darwin-arm64 failed with error 404
mediapipe %

try2

"try1 bug" said that bazel tried to Download bazel-3.7.2-darwin-arm64 from github release.
But, release version 3.7.2 don't have the type of darwin-arm64 .
https://github.com/bazelbuild/bazel/releases/tag/3.7.2
Fortunately, release version 4.1.0 have the type of darwin-arm64.
https://github.com/bazelbuild/bazel/releases/tag/4.1.0

Then I trid to Download bazel-4.1.0-darwin-arm64 .

do

In root repository "mediapipe", fix ".bazelversion" file as following.

4.1.0

Then, retried lesson 6 and the download started.

bug

But the download didn't complete successfully: I got the other bug as below.

// run lesson 6 again
mediapipe % bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world

Now situation

Then I gave up temporarily and am questioning to you!

Could someone solve this problem??
Thanks in advance.

Answer 1

I successfully built the HelloWorld.cc fine.

I also managed to compile Android on M1 MAC. Had some issues with NDK version and permissions but in the end it compiled and ran on my S8 Plus.

My setup

• MacBook Pro (13-inch, M1, 2020)
• macOS Big Sur 11.5.1
• ndk version used: r20b (download manually and edit WORKSPACE path to ndk)

During first compile you will get a lot of permission error issues, go to and keep open during build > System Preferences > Security and Privacy > general.

When an error pops up allow to continue and restart build. Will take about 8-10 permissions before it builds.

Below is the last bit of the build process.
