Build will fail at transmitter map

[andimik]

I understood that the map is not working for Ubuntu 22.04 (qt < 6.5.0)

Qt version < 6.5.0, transmitter map will not be available in TII dialog

but I cannot build the devel branch at all:

[KejPi]

I will check that in the evening but the QCustomPlot in Ubuntu 22.04 is not compatible either - currently I do not know how to check it's version from cmake. You would need to compile it from source and instruct cmake to take that version.

[andimik]

I've commented lines 63 - 263 (this is the map) in map.qml, it will continue till 96%.

But still no luck.

[KejPi]

Yes, but you do not have TII so it is pointless to play with development branch

[andimik]

Bad news: Qt 6.5 is too new even for Ubuntu 24.04 (which was released some days ago) and will be implemented in October release 24.10 only.

Legend:

Ubuntu 24.04 (Noble Numbat) Ubuntu 22.04.4 LTS (Jammy Jellyfish)

So we need to wait for AppImages.

[KejPi]

Yes, I was disappointed with their decision too and wasn't the only one. Qt6.5 was released more than year ago and it is LTS version as Ubuntu 24.04. To be honest I do not understand why they did not include and it was stupid decision IMO. If you want to stay with Ubuntu, you have 3 options - wait for AppImage, install Qt from official source (https://doc.qt.io/qt-6/qt-online-installation.html) (this is what I do) or find some unofficial Ubuntu repo with Qt 6.5.

[andimik]

I found another - let's say - attempt on https://forum.qt.io/topic/148418/how-to-install-qt6-latest-for-ubuntu-22-jammy-fish/7

see https://github.com/miurahr/aqtinstall

pip install -U pip
pip install aqtinstall
aqt install-qt linux desktop 6.6.0 gcc_64
aqt install-qt linux desktop 6.6.0 --archives qtbase qtmultimedia qtdeclarative qtsvg

The challenge is to install qt6multimedia. I could not find that :-(

It takes a while, then you need to declare the correct path in cmake:

cmake .. -DCMAKE_PREFIX_PATH=/home/andreas/6.6.0

The interesting thing is, it warns, that Qt is too old, although 6.6.0 is in use (I think so).

-- Found WrapVulkanHeaders: /usr/include  
CMake Warning at CMakeLists.txt:505 (message):

But due to missing qt6multimedia, it does not build.

On https://ddalcino.github.io/aqt-list-server/ you can see all packages.

And then I installed Qt 6.7.0 via online installer, but qcustomplot is not found ...

-- Checking for one of the modules 'qcustomplot'

-- Configuring incomplete, errors occurred!
See also "/tmp/AbracaDABra/build/CMakeFiles/CMakeOutput.log".

Then I checked https://www.qcustomplot.com/index.php/download, where the latest supported version is 6.4 ...

So I have no idea what to do and might to give up ...

[KejPi]

aqt can be the way to go, but I would really recommend to download official qt6 online installer, it installs to your home directory and it is very easy to install with simple wizard. Then you only need to take qmake from this installation and compile the app with that. You only need to call cmake with parameter like

-DCMAKE_PREFIX_PATH=$QT_PATH/lib/cmake

Where QT_PATH is path to your Qt installation/version/compiler

QCustomPlot can be compiled with QT 6.7 without problems but you need to compile shared library. When I am at my PC I can provide step-by-step instructions for Ubuntu 22.04 if you are interested.

[KejPi]

devel branch can be built under Ubuntu 22.04 with obsolete Qt version. If you set USE_SYSTEM_QCUSTOMPLOT=OFF when running CMake it should clone QCustomPlot library repo and build it during application compilation.

WARNING: Make sure that this library is then first in load path or better uninstall qcustomplot library from Ubuntu repository to avoid conflicts.

NOTE: Map will not be available for Qt < 6.5, there is not way to overcome this limitation because Qt Location was added in Qt 6.5.

[KejPi]

To build with manually installed Qt, use following CMake command:

cmake .. -DUSE_SYSTEM_QCUSTOMPLOT=OFF -DCMAKE_PREFIX_PATH=$HOME/Qt/6.5.3/gcc_64/lib/cmake

Considering version 6.5.3 installed in $HOME/Qt (replace with you path to gcc_64/lib/cmake)

Then after build I would recommend to run it with X.org instead of default Wayland:

QT_QPA_PLATFORM=xcb ./gui/AbracaDABra

Let me know if you need some help.

EDIT: @andimik I have an AppImage, so if you want to try the app without building send me a private message and I can share it with you.

[andimik]

Ok, I will (later).

I tried to build the main branch (9bc0bfdc96cc4f207a11b613431511d695d0321e) against the Qt6.7, but when I start the app, the language is English, and not system. Very strange, even when I delete the ini-file.

QT_QPA_PLATFORM=xcb

This only works when I install this:

sudo apt-get install libxcb-cursor-dev

[KejPi]

It seems it is not correctly reported from the system. I am not sure if I will be able to reproduce it and fix. I hope that at least manual language settings works.

EDIT: it works with 6.6.3 but not with 6.7.0. They have changed something or there is a bug. In either case translation files are not loaded with 6.7.0.

[andimik]

I tried the latest commit, but I found out that Qt6Positioning was not installed with 6.7.0, but with a different version in the directory /Qt/Tools/QtDesignStudio/qt6_design_studio_reduced_version/lib/cmake

So I could successfully compile it with your hint:

cmake .. -DUSE_SYSTEM_QCUSTOMPLOT=OFF -DCMAKE_PREFIX_PATH=~/Qt/Tools/QtDesignStudio/qt6_design_studio_reduced_version/lib/cmake

(German is working now)

Therefore, closing, many thanks for your efforts!

[KejPi]

I can see already firs issue with Ubuntu again 🙁 It seems that Unicode symbols are not supported by default font - there should be arrow symbol on table header, not rectangle

Hint: if you have transmitter database in CSV format, application can load it from $HOME/.cache/AbracaDABra/TII/dab-tx-list.csv

[andimik]

Looks good now. Thanks again.

In https://github.com/KejPi/AbracaDABra/blob/1f9105464986615318c7cae73a9ff1ef751b7573/gui/tii/txdataloader.cpp#L43

I fear you mean 2, not 3.

But why not use the same name as in qirx? I needed to rename that file or modify

https://github.com/KejPi/AbracaDABra/blob/1f9105464986615318c7cae73a9ff1ef751b7573/gui/tii/txdataloader.cpp#L105

[KejPi]

Yes, channel column is typo, thanks for pointing out, but channel column is not used so it does not harm.

I would like to implement automatic download of the database from FMLIST once I get an approval for that. Also I do not have any permission to use data from any other app and I do not actually want to use that data so I have chosen CSV file name for AbracaDABra as it is. Until I get an approval from the owner to use data from FMLIST database, it will be left to the responsibility of the user to get the data and to provide them to AbracaDABra in the expected location and format.

[andimik]

Understood.

Another screenshot, showing it works as expected (with live signals and xml-files)

BTW: Cool feature, that the channel selector uses the frequency information from the xml-header.

<Frequency Unit="kHz" Value="181936"/>

[KejPi]

Thanks, I would like to add also filename parsing to guess channel/frequency in case that XML is not inside.

BTW: did you set your location manually or is it provided from system on Ubuntu too?

[andimik]

When I chose system, the map stays in Prague, but the distance to all (!) transmitter is 0 km

So I used my GPS mouse on /dev/ttyACM0 which works (double checked with gpsmon tool) as well as the manual setting in my case.

I'm glad you have added a check if somebody enters the coordinates as xxx,xxx and not xxx.xxx ;-)

[KejPi]

This is actually an intended behavior. When you choose System and system does not provide valid location, the map is centered in Prague but there is no blue location point. Because application does not have valid location, the distance cannot be calculated so it is set to zero. But I think it would be less confusing for the user to leave it empty or N/A in the table in such case.

Thanks for confirmation that the serial GPS device works :-) I do not have any HW for testing it.

[KejPi]

Some more hints if you are interested: TII plot can be resized vertically or hidden by dragging the splitter between map and plot. You can zoom in the plot by mouse wheel (both axes) then drag the contents by mouse, or you can zoom only selected axis by clicking on it. Selection is cleared by clicking anywhere in plot area and zoom can be reset on right mouse click.

[andimik]

Yes, empty would be better instead of zero.

Scrolling in TII works.

But resizing the TII graph below the map seems to consume too much CPU power and will react very very slowly (I even got a warning as AbracaDABra is not responding any more, but clicked on "wait").

[KejPi]

I do not see any problem on Mac, I will add it to my list of Ubuntu issues :-(

[andimik]

But maybe this is related to internet connection?

[KejPi]

TII graph does not use any internet connection only map does. And it has also some cache so the bandwidth usage should not be high. I will try to reproduce the problem when I start my Ubuntu VM.

[andimik]

BTW: I confirm, that special characters are displayed correctly

[KejPi]

I know, we have many of them in czech ;-)

And by the way - the detector algo needs some tuning, if you find a case when it does not work, please report. You will probably see some fake TII codes, it seems to be too sensitive.

[andimik]

Any plans to reduce the sensitivity (in order to reduce fakes) or add a slider like in Qirx?

[KejPi]

As I wrote, I need to do algo tuning and also CPU usage optimizations when the performance optimizations will be finished. I prefer to avoid any manual controls of the algo.

[KejPi]

Yes, empty would be better instead of zero.

Scrolling in TII works.

But resizing the TII graph below the map seems to consume too much CPU power and will react very very slowly (I even got a warning as AbracaDABra is not responding any more, but clicked on "wait").

Just be sure - the issue is when you try to move the splitter between map and plot, correct (increasing or decreasing vertical size of graph)? I can se quite slow behavior on my Ubuntu VM (not that app is not responding) but to be honest I am not sure if I can solve it. It seems to be problem of QML/Map because even when I build the app without QCustomPlot support and I try to resize TII Dialog with map only, it is slow too.

[andimik]

Yes, this slider

[andimik]

There is another two problems (maybe in Ubuntu only???)

The TII window is in the foreground, even with Alt + Tab I cannot switch to the main window. Don't know if you aware of this.

Remark: The TII window can be placed to the left or right using Win-Key + Left/Right Arrow, but I cannot do that with the main window.

[KejPi]

There is a strange behavior of dialogs on Windows too (domehow related to Qt version)\ Do other dialogs do the same - Settings and Ensemble information?

[andimik]

I don't know why, but I can shift the main window now.

Bildschirmaufzeichnung vom 10.05.2024, 12:02:45.webm

All four windows,

• Settings
• EPG
• application log
• ensemble information

work, but they all are in the foreground although I can click on the main window and move it.

[KejPi]

Dialog windows behavior should be fixed now, you can try if you want.

[KejPi]

@andimik commented in #139:

Well, I thought I had success with your hints, but this is the output:

cmake .. -DUSE_SYSTEM_QCUSTOMPLOT=OFF -DCMAKE_PREFIX_PATH=~/Qt/6.7.0/gcc_64/lib/cmake/

  Found package configuration file:

  but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
  FOUND.  Reason given by package:

  Failed to find required Qt component "Positioning".

  Expected Config file at
  "/home/andreas/Qt/6.7.0/gcc_64/lib/cmake/Qt6Positioning/Qt6PositioningConfig.cmake"

  Configuring with -DCMAKE_FIND_DEBUG_MODE=TRUE might reveal details why the
  package was not found.

  Configuring with -DQT_DEBUG_FIND_PACKAGE=ON will print the values of some
  of the path variables that find_package uses to try and find the package.

Sorry, I do not want to mix the topics, co let's continue here. It is strange because I saw the TII dialog working in your screenshots.

Well, but the error suggests that you did not include Qt Positioning in your Qt 6.7 installation. You can start Maintenance Tool from Qt installation directory choose Add or remove components and check Qt 6.7 -> Additional libraries -> Qt Positioning.

[andimik]

I found that in my Qt version this is not existing

Let me try to install it from another version.

[KejPi]

Well, this is happening form time to time. Just uninstall (uncheck) Qt 6.7.0 and install Qt 6.7.1 or 6.5.3 that is LTS version. Just make sure that you add all necessary libraries. This is what I typically install:

You do not need all for sure, but Multimedia, Positioning, Location, Image Formats, Connectivity, Websockets is the minimum I would say.

[KejPi]

So what is your status? Are you able to build? I have pushed new version of the library and I would appreciate if you can test it and provide feedback.

[andimik]

Yes, I could build thanks to your hints. The older Qt version 6.5.3 is working.

[andimik]

https://github.com/KejPi/AbracaDABra/blob/095516133078daff5cd33df3b8ca6b3c979eef9d/README.md?plain=1#L236

In order to build devel branch, qt6-positioning-dev is necessary. So please add it to the README.md in the devel-branch.

sudo apt-get install qt6-positioning-dev

Tested under Ubuntu 24.04 (Linux Mint). No need to install separate Qt in this case (my Linux partition has crashed and therefore I've re-installed a fresh one), this means it will save a lot of disc space.

It will be qt6-positioning-dev:amd64 (6.4.2-3build3) then, and it works as expected.

You can build with Qt6.4 but with the functionality is limited. From my point of view, it is obsolete Qt version.

qml6-module-qtcore is required as well, btw. This is not mentioned in the readme.
