Platform development on MacOS isn't supported as of June 22, 2021.

[Connor Tumbleson]

I saw this message - "Important: Platform development on MacOS isn't supported as of June 22, 2021." when attempting to pull down AOSP on MacOS to build the platform/build tools.

I set it up via:

repo init -u https://android.googlesource.com/platform/manifest -b master -g default,tools
repo sync -c -j8
source build/envsetup.sh
lunch sdk-eng
make LOCAL_MULTILIB=64 USE_NINJA=false aapt

Is there an expected path of building just the tools (platform & build) with that announcement? It is getting tougher and tougher to build these platform/build tools on each release and not sure if I'm making something more difficult than it should be.

Running into error after error attempting a build leads me to believe I'm not doing this right.

> -g default,tools

The "tools" group in the manifest is unrelated to building these SDK tools, so that shouldn't be necessary (though all of the "tools" grouped projects are also in "default" currently, so it really shouldn't change anything either).

> LOCAL_MULTILIB=64 USE_NINJA=false

LOCAL_MULTILIB doesn't do anything on the command line, and ninja has been the only way to build for several releases now, so you can drop these. Just `m aapt` should work fine.

I think I just fixed this particular error with https://android-review.googlesource.com/c/platform/build/+/1760965 this afternoon, so if you sync or cherry-pick that change, your command should work. Building the actual SDK zip files on AOSP is still broken, and I'm working on refactoring those so that you don't need to build a system image in order to build the platform/build-tools zips.

Thanks, I was looking into groups that could cut down my clone size since only interested in platform/build-tools and assumed incorrectly.

Additionally thanks, just been re-using commands release after release and haven't taken a chance to dig into whether valid or not. I will adjust.

Thanks for the support. I'll watch for patches and follow along. Looks like latest was merged already.
