libcamera build failure with meson 1.3.0

[ChandanGirish]

I am trying to build for Android 13.0 and I followed steps in : https://github.com/raspberry-vanilla/android_local_manifest/tree/android-13.0 But I encountered some error after : lunch aosp_rpi4_car-userdebug

There should be an actual error message somewhere before that.

Have you followed the steps on establishing the build enviroment including installing the additional packages (IIRC libcamera needs some of the additional python libraries)? What Linux distro are you using to build?

[ChandanGirish]

Yes, I followed the steps on establishing Android build environment and repo installation. And then I installed additional packages as in Step 2. (https://github.com/raspberry-vanilla/android_local_manifest/tree/android-13.0)

Version: Ubuntu 22.04.3 LTS Refer meson-log.txt : attached log text

[KonstaT]

Ok, this is strange as I'm also on Ubuntu 22.04.3 LTS and I can't reproduce any issue with building libcamera. One difference I did notice is that I'm on meson version 1.2.3 while you have 1.3.0.

The meson build system that is used for building e.g. libcamera is actually a hack and not how libraries should be built on Android. Generally the AOSP tree also provides the necessary build tools but with the meson build system, the tools you have installed on your host machine also make a difference.

It looks like src/libcamera/base/meson.build:56:21: ERROR: shared_library keyword argument "version" Invalid Shared library version "". Must be of the form X.Y.Z where all three are numbers. Y and Z are optional. is the actual error. I don't know if newer meson versions need the project's version number to be set. For my libcamera fork I've specifically removed the version as it caused different issues (https://github.com/raspberry-vanilla/android_external_libcamera/commit/f6ffa1b401177788c257367aa55575bf36cb324c).

I had the same issue. downgrading the meson version to 1.2.3 from 1.3.0 did the job.

This is now fixed in android-14.0 and android-13.0 branches. Please sync your sources.
