Building on Linux (Debian) without Android support about lyra

[mchinen]

Thanks for the detailed report. I'm not sure, but if I had to guess it might be related to your bazel version if it is old enough that android_*_repository is not supported. Not sure what version is pinned for that Debian release.
bazel --version gives me bazel 4.0.0.

Seem to be version 3.5.1 in Debian 11 (bullseye) (bazel-bootstrap (3.5.1+ds-3)).

Have you run ./configure and set up Android SDK integration through the script instead?

OR

can you please try adding the attribute 'path = "/path/to/sdk/"' in the project's WORKSPACE file's android_sdk_repository() rule

Thanks for your help, but I don't intend to build for Android or install the SDK. I'm building for Linux only, and I don't think the Android SDK is needed to build a linux program ;)

I followed the instructions, built Linux on Ubuntu 20 fine.

@xnorpx right, I'm using Debian (I edited my post to give details) but I don't think the issue is related. Do you have the Android SDK installed?

[xnorpx]

@a-rose no, clean Ubuntu 20 WSL2 environment. Installed Bazel and then followed the Linux instructions and did not install anything Android related.

( Comment was mostly to confirm that Linux does build outside of g. )

Ok then, the issue is only with Debian (after all, the docs said only Ubuntu was tested).

I would still like to find a way to make it work with other distros to help the project :)

Confirmed to work with bazel v4.0.0 from https://github.com/bazelbuild/bazel/releases. Thanks everyone !
