<![CDATA[Help creating an UBSync arm64 version]]>Hi,
I am not sure, if @ernest, who developed UBSync is still active.
https://code.launchpad.net/~ocs-team/owncloud-sync/UBsync

For some time I am trying to create an arm64 version of UBSync.
Problem is, that the background service cannot be started.
I think, that I have found the main issue: it is using precompiled libraries and binaries. In detail this is:

  • libowncloudsync.so.0
  • libowncloud_csync.so.0
  • owncloudcmd

I tried two ways so far:

  • replace this files with arm64 pendants, which I found in debian repositories
    • that did not work yet
  • compile complete "owncloud client" myself
    • did also not work

So if you has some free time and experience, you are welcome to help me, finding a way to make a working arm64 version of this app.
Thanks 🙂

If you had the previous version and you still have old config, it will not work. The paths are now different, as it was necessary to unify them to enable multiarch: is this issue helpful?

However, I also experienced troubles with starting the service, which were solved by service restart(s) ... I have only "ported" and "multi-arched" the build process, but unfortunately I don't have experience with the app.

@ernest As pointed above, I guess, there are severe issues and inconveniences related to the QT application or the service, unfortunately I have very limited experience with QT a QML. My current job limited to the build process and "grep&replace" code snippets. On the other hand this app looks to be essential for many users trying ub-touch (including me)... I agree, lets try to remove the "worst case issues" and somehow push it to the open-store.

@ernest I shared my telegram alias with you through the chat

Are you on telegram ? let's find a smooth way for the users to upgrade on openstore.

Testing using Volla phone, OTA-16 RC, I was able to add my Nextcloud account (hosted by OwnCube) and setup my sync folders - but I got an error message ("! Start Service") when I press the "Start" button in the "Sync Service" page.

I believe, that most of the steps are correct, but especially, the 32bit build needs a re-revision - it should be principally equal as the forked one - the same binaries (I only changed paths to enable multiarch).

Changes are described in README.

I had no luck with including the build process into the package itself because it went me into the dependency hell in the container (given probably by mixed repos in the default container - I'm not experienced enough with clickable and docker to deal with in reasonable time). I also experienced errors (Access Forbidden) with the ubports binaries of owncloudcmd extracted from deb packages. The same I experienced for some of older self-compiled owncloud versions. I finally build v2.5.3 in libertine, extracted binaries and it works.

The fork is now on my GitHub
The 64-bit click package is also there for testing

Why do you want to build it by yourself ?

Yes i did build the lib by myself and change the arch in the code to arm64.

So, did you build the shipped binaries by yourself? If yes, perhaps you could tell me what is needed to build them and I could try to integrate it in a clickable build.

The last time I tried to build the the needed binaries, I have had no luck, but I also was not sure, if I even got the right sources...

Usually brian asks for the source, compile it by itself and upload the packages.

So if the source are not public, no upload.

I don't get the problem.

As explained, the code between arch version has to be the same on openstore. Currently the app has been written in c++/qml with hardcoded arch...
Thus the code needs to be updated for multiarch... It's beyond my capabilities.

How were you able to install it ??? on arm64 phone

I built an arm64 version of ubsync... but the contained pre-compiled owncloud libraries were still armhf. And I think the qmake .pro-file did also create armhf path's and so on...

I wouldn't be surprise there is a remaining bit of armhf code somewhere.(How were you able to install it ??? on arm64 phone)

I suggest to remove the app and search manually for any ubsync and Nextcloud or Owncloud related, then delete them.
like sudo find / -iname "ubsync"

In that file the exec was referring to the wron path: ..../arm-linux-gnueabihf/...
I changed it to "aarch64-linux-gnu" and now it works!

Obviously that file is not getting purged, when clearing app data with UT-Tweak-Tool, because it is not part of the app-directory...

Edit:
Hm, but it is still not possible to trigger a sync from within the app.
There is an error that it could not find libowncloudsync.so.0: https://paste.ubuntu.com/p/Wzp55yHnvq/

But I can still trigger the sync with the terminal command.

On my side the app doesn't any issue on a fresh install ;), so I doubt apparmor.

likely while playing you messed up something.
please ensure that the file is correct, as below.

Look into .config/ubsync/ubsync.conf, ensure that your timer is different than 0

Interestingly the command works and my folder gets synced: https://paste.ubuntu.com/p/CXf3VWmB3n/
After executing the command, the app also shows a "last-synced" date. The service status still is "Stopped".

So the service just cannot be started by the app. Perhaps it is an AppArmor issue?!

If you want to start manually the daemon this is the command:

LD_LIBRARY_PATH=/opt/click.ubuntu.com/ubsync/current/Owncloud-Sync/lib/aarch64-linux-gnu/lib/ && /opt/click.ubuntu.com/ubsync/current/lib/aarch64-linux-gnu/bin/OwncloudSyncd

You can play with it according to : https://doc.owncloud.org/desktop/2.1/advancedusage.html

An example of output.
https://paste.ubuntu.com/p/R3DwRYtxmR/

Looking back at the code, I remember why I didn't push the arm64 ... the type of architecture is hardcoded and i don't know the c++, making the journey quite hard. So any help is welcome for that.
