build question #139

IzzySoft · 2024-11-06T23:01:58Z

I've followed the build instructions from the Readme to my best understanding, ending up with this build recipe:

          - git clone https://github.com/rust-lang/rustup.git -b 1.25.1
          - export ANDROID_NDK=/opt/sdk/ndk/${PROVISIONING_NDK}
          - ${BUILD_REPO_DIR}/rustup/rustup-init.sh -y --target armv7-linux-androideabi --target aarch64-linux-android --target i686-linux-android --target x86_64-linux-android
          - source $HOME/.cargo/env
          - cargo install cargo-ndk
          - cd android
          - ./gradlew assembleRelease
          - find . -name '*.apk'

However, the only APKs found are:

+ find . -name '*.apk'
./app/build/outputs/apk/bluetooth/release/app-bluetooth-release-unsigned.apk
./app/build/outputs/apk/demo/release/app-demo-release-unsigned.apk

not the android/app/build/outputs/apk/release/app-release-unsigned.apk the readme mentions. As I didn't want a demo, I took the other one – but that's a 64 MB APK instead of the expected 7.5 MB one your releases indicate.

Can you please let me know what I might have done wrong there? Thanks in advance!

The text was updated successfully, but these errors were encountered:

Oppzippy · 2024-11-07T00:41:32Z

app-bluetooth-release-unsigned.apk is the correct one, my mistake. ./gradlew assembleRelease by default should strip debug symbols from binaries, but that's probably not happening if the apk is 64MB. Are there any warnings about that failing?

Oppzippy · 2024-11-07T00:48:39Z

One other mistake I had in the build instructions: ./gradlew assembleBluetoothRelease should be used instead of ./gradlew assembleRelease to skip building the demo variant.

IzzySoft · 2024-11-07T07:54:00Z

Yes, I remember some "unable to strip" – but must admit I paid them not too much attention as I see them quite often (background: https://codeberg.org/IzzyOnDroid/rbtlog – as you can see, there are already hundreds of apps covered, and yours would be the second Rust one).

Thanks for confirming I've picked the correct APK, and also for mentioning the flavor to include to skip the demo one. I could run the build again and provide you the full log if it helps. I've also kept the APK, so I can peek into it to compare sizes. Here're the .so from mine:

So yes, it's them (especially libopenscq30_android.so).

In case it matters: build was running on Debian bookworm with OpenJDK 17 and NDK 27.2.12479018 (which I've picked from your build.gradle).

Oppzippy · 2024-11-07T22:09:17Z

By any chance, are you building the latest tag (ndk version 26.3.11579264) but using the ndk version from master? I fixed some more issues in the build instructions and came across that problem. It seems stripping debug symbols is the only step that ignores ANDROID_NDK_HOME and specifically looks for $ANDROID_HOME/ndk/specified_ndk_version, so it's the only part that will fail with the wrong ndk version. ./gradlew stripBluetoothReleaseDebugSymbols --info shows the paths it checks for the ndk.

IzzySoft · 2024-11-07T22:52:31Z

By any chance, are you building the latest tag (ndk version 26.3.11579264) but using the ndk version from master?

Close. I built from the latest tag. I sometimes indeed forget to switch to the tag when checking (checking…) oof, straight hit: the tag specifies r26d, I've used 27, grmpf… OK, recipe adjusted, running another build now.

Does the NDK used change often? Then I'd mark your app's recipe for manual check should the build be RB now, with a note telling me where to look for the NDK to be updated (well, in the build.gradle.kts at the corresponding tag of course).

(build reached gradlew meanwhile – I catch myself something to drink before I check again…)

OK, looks much better: difference now is down to half a Megabyte now!

Took 10min as I forgot to change assembleRelease to assembleBluetoothRelease – so next run would probably be around 7 min. Still wonder where the remaining diff comes from now. Which version of rustup are you using? I couldn't find that mentioned. Build here was running with 1.25.1 (as that was used by another app, and I more-or-less copied and adjusted the rustup part from there). Let me retry with 1.27.1 (the latest one there), will report back when the build is through. And run again if you have another hint.

IzzySoft · 2024-11-07T23:08:08Z

OK, that didn't change much (except for build time being 1min less, around 9 min now). APK has the same size (to the byte) as it was with 1.25.1.

Oppzippy · 2024-11-07T23:50:06Z

My process for releases is:

Build using github actions (android here: https://github.com/Oppzippy/OpenSCQ30/blob/v1.13.1/.github/workflows/build.yml#L142-L171)
Download everything
Sign the apk
Sign everything with gpg
Make a release on github and upload all of it

Rust is installed using dtolnay/rust-toolchain@stable, which uses the already installed version of rustup if available. The Github actions runner image currently has, and had at the time of OpenSCQ30 v1.13.1, rustup 1.27.1 installed (https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md#rust-tools).

I generally update the ndk version as new versions are added to github actions runner images so that I can have the workflow use the latest ndk. For convenience, I added a script at android/scripts/get-ndk-version.sh to print the current ndk version specified in build.gradle.kts.

Rust 1.80.1 was the latest stable version when OpenSCQ30 v1.13.1 was released, so that's the one that was used to build it.

Oppzippy · 2024-11-07T23:57:07Z

I can switch to building in a debian container if that would make things simpler.

IzzySoft · 2024-11-08T08:46:35Z

Build using github actions

That's what I oriented on and took most of the steps from. Differences here are: Debian bookworm instead of Ubuntu (should not make a difference in my experience), OpenJDK-17 instead of Temurin (rarely makes a difference – and as the diff lies in the .so files, it's unlikely to be the JDK I'd say), and installing rust via cloning the rustup repo and running their init script instead of rustup directly. No signing here of course (I don't have your keys). Full recipe looks like this:

notes:
  - ends up with a bigger file (initially 64 MB due to NDK) than the expected 7.5 MB from upstream, see https://github.com/Oppzippy/OpenSCQ30/issues/139

And yeah, I could try with e.g. image: ubuntu:jammy as well, but I doubt that would change much. Would be different had you built using Fedora, or even Windows. But Debian and Ubuntu are close enough to each other.

Resulting APK here has 8420837 bytes (instead of the 7731308 bytes the APK from your releases has).

I added a script at android/scripts/get-ndk-version.sh to print the current ndk version specified in build.gradle.kts.

Thanks, but I'll need to took that up manually anyway as installing the APK is part of provisioning, so it cannot be done inside the build: part.

Rust 1.80.1 was the latest stable version when OpenSCQ30 v1.13.1 was released, so that's the one that was used to build it.

Rust is installed by rustup; I didn't check which version it grabbed. I can see to capture the log on the next run and attach it here (zipped), maybe something there catches your eye?

Oppzippy · 2024-11-08T15:27:26Z

The rust version seems to be the issue. When building with rust 1.80.1, I get within a few hundred bytes of the expected size. When I use the latest stable, which rustup will install by default, I get within a few hundred bytes of the size you're getting.

IzzySoft · 2024-11-08T16:07:08Z

Strange. So how can we tell rustup to install the version we need? --default-toolchain=1.80.1? I can try that. If we can work this one out, it might be a good idea to pin those versions e.g. via a config file:

rust: 1.80.1
rustup: 1.27.1

Those I then could fetch in the build recipe here to match what you've used.

Wow, that's indeed pretty close now:

Recipe:

build:
  - git clone https://github.com/rust-lang/rustup.git -b 1.27.1
  - export ANDROID_NDK=/opt/sdk/ndk/${PROVISIONING_NDK}
  - ${BUILD_REPO_DIR}/rustup/rustup-init.sh -y --default-toolchain=1.80.1 --target armv7-linux-androideabi --target aarch64-linux-android --target i686-linux-android --target x86_64-linux-android
  - source $HOME/.cargo/env
  - cargo install cargo-ndk
  - cd android
  - ./gradlew assembleBluetoothRelease
  - find . -name '*.apk'
  - mv app/build/outputs/apk/bluetooth/release/app-bluetooth-release-unsigned.apk /outputs/unsigned.apk

And now it gets funny. I've run strings over the arm64 libopenscq30_android.so of your and my APK, then diffed the output. Wanna see? strings.diff.gz For example, my APK includes which NDK was used (r26d), yours does not. Bummer. But see for yourself…

IzzySoft · 2024-11-08T16:10:03Z

PS: Your APK was built 2024-08-31, so rust 1.80.1 was not yet released (that came 5 days later), it must have been rust 1.80.0. I'll run again with that now…

Oppzippy · 2024-11-08T16:24:21Z

I think 1.80.1 should be correct, since it was tagged on August 8. Not sure why the github release says September 4.
https://github.com/rust-lang/rust/tags

IzzySoft · 2024-11-08T16:31:09Z

1.80.0 didn't make much difference (in fact it added a few bytes on top, though not many). OK, then maybe the diff rings a bell with you… Maybe something similar with cargo, a la cargo install --version xxx? Are the versions of the dependencies pinned, or could it be I get some newer versions here now?

Oppzippy · 2024-11-08T16:48:39Z

cargo dependencies are pinned in Cargo.lock, so that shouldn't be an issue.

Ok, I think this part of the diff explains the problem.

+Android (11349228, +pgo, +bolt, +lto, -mlgo, based on r487747e) clang version 17.0.2 (https://android.googlesource.com/toolchain/llvm-project d9f89f4d16663d5012e5c09495f3b30ece3d2362)
+Linker: LLD 17.0.2

-Linker: LLD 18.0.1

I think v1.13.1 was compiled with a mix of two ndk versions. I realized the other day that when it was released, ndkVersion in build.gradle.kts wasn't set to the latest version, but I had github actions setting ANDROID_NDK_HOME to whatever the latest was. So the things that respect ANDROID_NDK_HOME used the latest version, and things that don't used the older version, leading to the mixed versions being used.

I ran a build just now if you want to compare against the d1ef781 apk instead, which has that issue fixed.

edit: fix ANDROID_NDK_HOME typo

IzzySoft · 2024-11-11T09:28:29Z

Apologies for the delay, I had a guest this weekend and close to no time for looking at my computer…

Have been running the APK against the indicated commit, APK diff does not look much different unfortunately:

Now I wanted to compare the output of strings libopenscq30_android.so again, but I decided I can skipp running diff – output of ls -l will tell you why:

-rw-rw-r-- 1 izzy izzy 5151284 Nov 11 10:15 local.strings
-rw-rw-r-- 1 izzy izzy   61203 Nov 11 10:15 upstream.strings

100 times more strings in my build it seems. Recipe was basically unchanged:

- git clone https://github.com/rust-lang/rustup.git -b 1.27.1
- export ANDROID_NDK=/opt/sdk/ndk/${PROVISIONING_NDK}
- ${BUILD_REPO_DIR}/rustup/rustup-init.sh -y --default-toolchain=1.80.1 --target armv7-linux-androideabi --target aarch64-linux-android --target i686-linux-android --target x86_64-linux-android
- source $HOME/.cargo/env
- cargo install cargo-ndk
- cd android
- ./gradlew assembleBluetoothRelease

Now I'm confused. Looked inside the strings files for clang version:

- Android (12470979, +pgo, +bolt, +lto, +mlgo, based on r522817c) clang version 18.0.3 (https://android.googlesource.com/toolchain/llvm-project d8003a456d14a3deb8054cdaa529ffbf02d9b262)
+ Android (11349228, +pgo, +bolt, +lto, -mlgo, based on r487747e) clang version 17.0.2 (https://android.googlesource.com/toolchain/llvm-project d9f89f4d16663d5012e5c09495f3b30ece3d2362)

Still a different version. I can specify a cmake version in the recipe file, but I have no idea how to specify clang. Or why my output is so much more verbose than yours for strings…

Oppzippy · 2024-11-11T14:27:18Z

Sorry, guess I should have specified. The master build is using rust 1.82 and NDK version 27.2.12479018, so when comparing against that rather than v1.13.1, you'll need to change the versions.

IzzySoft · 2024-11-11T23:10:38Z

Oof… yeah, with those many apps I deal with daily, being explicit in such cases is helpful 🙈 ok, so this recipe:

- git clone https://github.com/rust-lang/rustup.git -b 1.27.1
- export ANDROID_NDK=/opt/sdk/ndk/${PROVISIONING_NDK}
- ${BUILD_REPO_DIR}/rustup/rustup-init.sh -y --default-toolchain=1.82.0 --target armv7-linux-androideabi --target aarch64-linux-android --target i686-linux-android --target x86_64-linux-android
- source $HOME/.cargo/env
- cargo install cargo-ndk
- cd android
- ./gradlew assembleBluetoothRelease

with ndk 27.2.12479018 and JDK 17.

OK, that one seems to match this time. Something else must be amiss.

Ah, that gives me a clue this time, let me check…

build_home_dir: /build
build_repo_dir: /build/repo

Hm, and github actions, huh? So:

build_home_dir: /home/runner
build_repo_dir: /home/runner/work/OpenSCQ30/OpenSCQ30

should do the trick. Now I'm curious… Ha! Look what I got there:

    "upstream_signed_apk_sha256": "654639d50123fd2cfc78ff49b90cdb1e1bbeabc67fde18873fb27b5c5f8b2905",

    "signature_copied_apk_sha256": "654639d50123fd2cfc78ff49b90cdb1e1bbeabc67fde18873fb27b5c5f8b2905"

That means we succeeded with an RB (both signed APKs are byte-identical, thus showing the same hash) 🥳 Any ETA for the next release, based upon this? 😃

Oppzippy · 2024-11-12T14:41:16Z

Nice, thanks for your work on this. There's not really anything major left for the next feature release, so it'll probably be in around a week or so.

IzzySoft · 2024-11-12T15:11:43Z

Cool! Please give me a ping then (err, I guess as this issue is solved, closing it once the release is up would serve that purpose as well). Glad we finally figured it out – and thanks a lot for all your help and patience with the process!!! 🤩
