Please update/verify build instructions

[Giszmo]

I tried to compile the Android wallet and while I don't have a Mac, I didn't even succeed to check out all the code required.

git submodule add --force -b main https://gitlab.com/nunchuck/libnunchuk.git

looks wrong. The GitLab project does not exist, at least not publicly.

The project has a git submodule defined but it's this non-existing repo to a different path than the build instruction says.

I tried working around this by using ninchuk-io's GitHub alternative but there, a dependency failed to clone:

$ git submodule set-url src/main/native/libnunchuk https://github.com/nunchuk-io/libnunchuk.git
$ git submodule update --init --recursive
Cloning into '/home/leo/tmp/nunchuk-android-nativesdk/src/main/native/libnunchuk'...
Submodule path 'src/main/native/libnunchuk': checked out 'c168cf715cbe768b5cd5004609f2db6d0ebfe254'

So ... we can't clone that dependency. Seriously?

$ git clone https://github.com/sqlcipher/sqlcipher

Thanks @Giszmo , i've updated libnunchuk submodule url (https://github.com/nunchuk-io/libnunchuk.git).

It seems sqlcipher repo has a file with zero-padded file modes

% git fsck   

Checking object directories: 100% (256/256), done.
warning in tree e35e28f52d20df27561b2780f6b9c86669a9de21: zeroPaddedFilemode: contains zero-padded file modes

Normally it's only a warning. But if you enabled receive.fsckObjects and transfer.fsckObjects config it will stop you from cloning the code. You can check it with git config --list command

% git config --list                                  
receive.fsckobjects=true
transfer.fsckobjects=true

Please unset these 2 configs and retry

% git config --global --unset receive.fsckObjects
% git config --global --unset transfer.fsckObjects

[Giszmo]

Ok. Now I remember I did activate the fsck and was wondering why it wasn't on by default. Now I'm wondering what are the consequences of zeroPaddedFilemode.

Either way I'll figure out how to compile your app.

it's possible to build this repo on linux with instructions more or less like: (tested on debian)

1. Install commandline tools & ndk 21.0.6113669 (or reuse newer ndk 21.4.7075529 installed by gradle if no new ndk installed yet) and setup all needed android env vars (ANDROID_*), related issue is to specify ndkVersion in build.gradle Add ndkVersion with static value to build.gradle for newer&reproducible NDK usage and use newer supported version #4
2. Install packages: (looks like ibboost-dev and libevent-dev are not needed, they from documentation, it compiles without installing them, the build process itself compile boost version)
   git automake libtool libboost-dev pkg-config libevent-dev openjdk-11-jdk make curl bzip2 gcc unzip g++ patch
   unzip needed only if used to unzip ndk downloaded directly from google via curl command to use specified version instead of currently default version installed with gradle with commands:

    cd /home/appuser/app/sdk/; \
    curl -o commandlinetools.zip -L https://dl.google.com/android/repository/commandlinetools-linux-9123335_latest.zip; \
    echo "0bebf59339eaa534f4217f8aa0972d14dc49e7207be225511073c661ae01da0a  commandlinetools.zip" | sha256sum -c; \
    unzip commandlinetools.zip; \
    rm commandlinetools.zip; \
    /home/appuser/app/sdk/cmdline-tools/bin/sdkmanager --sdk_root=/home/appuser/app/sdk/ --install "ndk;21.0.6113669";

3. avoid git submodule add call (not needed anymore after recent change)
4. Run script .install_linux_deps.sh instead of .install_deps.sh and use bash instead of sh to invoke it, related issue Make .install_linux_deps.sh sh compatible or add bash shebang to it #3

Edit: Containerfile to compile repo

Container file in previous comment wont work anymore on current version due to issue #5
Containerfile and rb test of nunchuk 1.9.23 version is in issue: nunchuk-io/nunchuk-android#7

[Giszmo]

@emanuelb I tried your container file and it failed at ./gradlew publish at least with podman:

but it doesn't abort.

Edit: It fails with the same error using Docker.

[emanuelb]

Yes, you tried the old Containerfile that doesnt work anymore for the latest version on google-play (it worked for the code they published before when the comment was made), the error you see is fixed in #5

Use the newer Containerfile for latest version that is in issue: nunchuk-io/nunchuk-android#7 (comment)
