Information about prebuilt ckati

[Rounak Agarwal]

Is there a way to find out the exact commit and the build command used to build the prebuilt ckati executable available in AOSP project prebuilts/build-tools ?

[Dan Willemsen]

There's a manifest.xml in that project that should have all of the exact revisions: https://android.googlesource.com/platform/prebuilts/build-tools/+/refs/heads/master/manifest.xml. It's a snapshot of the platform/manifest build-tools manifest.

It's built using the prebuilts/build-tools/build-prebuilts.sh script, and you can get the full artifacts from the aosp-build-tools branch on ci.android.com. The commit message updating the prebuilts should reference a build number that can be found on ci.android.com.

Thanks for the information Dan.

I wanted to try and build the binaries myself. I did the following :

repo init -u https://android.googlesource.com/platform/manifest -b build-tools
repo sync -c
export OUT_DIR=$PWD/out
./prebuilts/build-tools/build-prebuilts.sh


It got stuck at the following command :

build/soong/soong_ui.bash --make-mode --skip-make <Huge list of output paths>

Do you know what might be the reason for this ?

Strange. Are you able to do regular builds of AOSP master on your machine? (If not, don't worry, it's just a data point if you have)

What does the end of out/soong.log look like? That'll narrow down the problem.

If you have a slow disk, the first time you run this, it may take a while as it builds up a database of the files in the source tree, but it shouldn't take that long (on a sufficiently fast machine that should only take a few seconds). If you happen to have mounts / hard links / etc that expose more files or a network mount inside the source tree, we've seen hangs when we generate this db.

Sorry for the delay in replying. By the time my previous reply got through moderation the build had resumed and it ran successfully.
