Hi @Ramees025,

Please run this command after navigating to the MediaPipe cloned repository on your local machine and let us know if you can build it successfully.

chmod +x setup_android_sdk_and_ndk.sh
./setup_android_sdk_and_ndk.sh

Thank you!!

The error message you're encountering suggests that Bazel is attempting to create symlinks outside of the repository directory, which is not allowed.
Steps to resolve the issue:-

1. Check NDK Path:
   Ensure that the NDK path in your WORKSPACE file is correctly set and points to a valid NDK installation. The path should not include the symlinks that Bazel is attempting to create.

android_ndk_repository(
    name = "androidndk",
    path = "/home/test/Android/Sdk/ndk/21.4.7075529",  # Update with your actual path
)

2. Update NDK
3. Check Permissions:
   Ensure that you have the necessary permissions to access and write to the directories involved. This includes the Bazel cache directory and the NDK directory.

sudo chown -R $(whoami) /home/test/Android/Sdk/ndk-bundle
sudo chown -R $(whoami) /home/test/.cache/bazel

4.Use Correct Bazel Version:
Ensure you are using a compatible version of Bazel. MediaPipe might require a specific version. Check MediaPipe's documentation for the recommended Bazel version and install it.
5, Clean Bazel Cache:
Sometimes, Bazel's cache might be corrupted or outdated. Cleaning the cache might resolve the issue.

bazel clean --expunge

6. Check WORKSPACE Configuration:
   Ensure your WORKSPACE file has the correct configuration for the Android NDK.
   sample snippet:-

android_ndk_repository(
    name = "androidndk",
    path = "/home/test/Android/Sdk/ndk/21.4.7075529",  # Update this path
    api_level = 21  # Or your desired API level
)

7. lastly, Final Command
   Once all configurations are corrected, try running the build command again:

bazel build --cxxopt=-DABSL_FLAGS_STRIP_NAMES=0 -c opt --config=android_arm64 mediapipe/tasks/cc/genai/inference/c:llm_inference_engine_cpu_main

Hope this helps, Thanks
