Android archive build

[danielvera64]

Hi,

I'm trying to build the Android archive using

    bazel build -c opt \
    --host_crosstool_top=@bazel_tools//tools/cpp:toolchain \
    --fat_apk_cpu=arm64-v8a \
    //mediapipe/lluvia-mediapipe/java/ai/lluvia:lluvia_aar

but I'm getting the following error

ERROR: /home/daniel/.cache/bazel/_bazel_daniel/2303dac16476e51ac6f2af5c006f9287/external/lluvia/lluvia/cpp/core/BUILD.bazel:19:11: Illegal ambiguous match on configurable attribute "linkopts" in @lluvia//lluvia/cpp/core:core_cc_library:
@lluvia//:linux
@lluvia//:android
Multiple matches are not allowed unless one is unambiguously more specialized.

Can you tell me if I'm missing something?
Thanks

Hi,

I'm not able to replicate that particular error. However, I'm having other compilation errors when building the AAR (working on a fix). Could you provide the following information?

• Host operating system.
• Mediapipe branch/commit/version.
• Lluvia branch/commit.
• Android SDK and NDK versions.

Could you try your build with the latest master version of this repo? I fix something regarding Android build in the rules_vulkan dependency.

Hi,
I pulled your changes but I'm still having the same error. Here is my information

Host operating system: Ubuntu 20.04.6 LTS (kernel 5.15.0-76-generic)

Let me know if you need more information.
Thanks for your help.

Thanks for the extra info. I'm able to reproduce the problem on my machine (Ubuntu 22.04 LTS x86_64).

It seems that the latest versions of Mediapipe started using Bazel 6.1.1. Running the AAR build command gives the exact problem you see.

I will be working on a fix for this repo and rules_vulkan, as they share the same logic to select config settings.

If possible for your use case, you could give it a try with Mediapipe v0.9.2.1

[danielvera64]

With Mediapipe v0.9.2.1 I was able to compile the Android build.

Thanks!

Hi, I merged a solution to master. It works with the latest version of Mediapipe and Bazel 6.1.1.

Could you verify if it also works in your setup?

Thanks :)

[jadarve]

Closing as inactive. Feel free to re-open the issue if the current version in master does not work.

Hi @jadarve ,

Sorry for the delay I was able to build the Android archive with your latest changes, Bazel 6.1.1 and Mediapipe 0.10.3

Thank you for your help

[jadarve]

Cool! Thanks for reporting the issue 😄
