Incompatibility of the used Qt library and the installed SilentDragonLite-aarch #61

After days of trying to fix it myself it seems I might want to ask some help.

The file to the .AppImage can be found by hash in our room: dc840e30ae4300350ff3aea93e5835751b2eabddea7767f3365957a509c2159d

The exact problem I see is:

./SilentDragonLite-aarch64.AppImage 
./SilentDragonLite-aarch64.AppImage: relocation error: ./SilentDragonLite-aarch64.AppImage: symbol _ZN20QTextStreamFunctions4endlER11QTextStream version Qt_5 not defined in file libQt5Core.so.5 with link time reference

In one line relocation error: ./SilentDragonLite-aarch64.AppImage: symbol _ZN20QTextStreamFunctions4endlER11QTextStream version Qt_5 not defined in file libQt5Core.so.5 with link time reference

If I understand correctly there is an incompatibility of the used Qt library and the installed SilentDragonLite-aarch.

My current set up is:

A little update after compiling on the same host. I got a QTBUG-72555, to fix it I need to compile Qt to 5.12 or newer version which is not super easy, but luckily we have compile-qt5-from-source.md.

The problem solves by editing .ui file directly with some text editor(not qtdesign) and removing all blocks that contains "PlaceholderText ".

The above fixed the issue temporarily, below is what I have after running sdl:

Checking if lite server  "https://lite.hush.land"  is a alive, try= 2
litelib_process_response :  Error: Cannot read wallet. No file at /home/devuan/.silentdragonlite/silentdragonlite-wallet.dat

.silentdragonlite folder is empty. Most likely I need to go with the newest Qt to make it work which I will do next. Also sdl_01.png is how GUI looks like.

@onryo if SDL crashed previously, after it created the ~/.silentdragonlite directory but before it created the wallet, it might not like that. Try deleting the empty directory and see if anything different happens.

Our code should probably handle this case automatically.

if SDL crashed previously, after it created the ~/.silentdragonlite directory but before it created the wallet, it might not like that.

It happened again even with a compiled Qt 5.15.2 on my HushBox.
To fix it I just need to wait a minute or so, I wasn't patient and that's why it happened.

Nevertheless, now I have SDL working on my armDevuan Pi 4 HushBox device.
So far it looks fine, but I will test HushChat later.

To fix it I just need to wait a minute or so

It's needed only on a first run, when you run SDL for the second time the GUI works as it supposed to be.

Next I will create HushBox-Qt-5.15.2-aarch64.deb

Next I will create HushBox-Qt-5.15.2-aarch64.deb

It might be not needed, the most time consuming process is compiling Qt. (~5 hours)

It's needed only on a first run, when you run SDL for the second time the GUI works as it supposed to be. sounds like a bug that could be fixed, it should retry and/or maybe sleep before looking for the wallet

@onryo if you can tell me what your STDOUT debug prints look like, when it fails the first time with an empty ~/.silentdragonlite , I can try to fix this bug. My guess is that on a normal powerful laptop, this bug doesn't happen by luck, but on a machine with less CPU resources and/or slower disk, the filesystem hasn't finished writing things to disk before code runs that looks for that stuff.

Yes, it relates to CPU usage or a slower disk on my Pi4, also happened some time ago on my old PC. Let me see if I can reproduce this bug by removing the folder. @duke
Just like the issue below, but not sure if I saw anything useful in STDOUT.

@onryo ok, you are probably right that there is maybe not useful STDOUT output. There may be something useful in SilentDragonLite.log file, but maybe not.

From src/connection.cpp the code will send no Plaintext wallet.dat to the log file (but not STDOUT) if it cannot find a wallet. I think the simple potential fix is to sleep 1 or 2 seconds and try again if this happens.

The initial issue was fixed.
A new issue will be created to track the activity for the startup screen bug on slow machines.
