LinSSID detects 6 GHz networks, lists their frequency correctly, but the channel number ist always 0. The 6 GHz networks are shown in the 5 GHz graph on the extreme left side. They should be in an own graph with correct channel number. The protocol column of the table omits 802.11 a, ax and be capabilities. My 802.11be networks are shown as "bg" when they should be "abgnacaxbe".

LinSSID won't launch giving the error "qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found."

2025-01-28T07:50:59.981000Z

I'm running Arch Linux with Hyprland and downloaded LinSSID through the Arch repository but anytime I launch it it prompts me for my root password and after entering the password it crashes giving this output when run in terminal.

Authorization required, but no authorization protocol specified

qt.qpa.xcb: could not connect to display :1
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted

running with the ~~~QT_DEBUG_PLUGINS~~~ variable set to 1 yields the exact same output with no further information. When checking journalctl this is all it shows.

I have tried reinstalling the app, Removing the app and installing it again, and reinstalling the app and all it's dependencies, but still the same error.

Fail to build on armhf (armv7+): error: cannot convert ‘long int’ to ‘const time_t’ {aka ‘const long long int*’}

Dear developer,

The package linssid is no longer compatible with armhf. Please, see below:

MainForm.cpp: In member function ‘void MainForm::doLogData()’:
MainForm.cpp:1296:68: error: cannot convert ‘long int’ to ‘const time_t’ {aka
‘const long long int’}
1296 | std::strftime(nowStr, 100, "%Y/%m/%d.%H:%M:%S",
std::localtime(&MainForm::now));

^~~~~~~~~~~~~~

| long
int

A full log is available at https://buildd.debian.org/status/fetch.php?pkg=linssid&arch=armhf&ver=3.6-8%2Bb2&stamp=1711139760&raw=0

Could you check this issue?

Regards,

Eriberto

Build fails with gcc11

The attached patch fixes the problem for me.

Build fails with gcc11

Correction, I suspect this is caused by qwt 6.2.0.
Anyway I'm at loss.

Using linssid 3.6 on openSUSE Tumbleweed. After (I believe) updating to gcc11, I see a build error, see attached log.

LinSSID 2.2 Not finding any networks?

2020-08-26T03:47:58.880000Z

Hi! I found the same behaviour. It's a Dell Vostro machine with Ubuntu 16.04 LTS. When I first installed LinSSD, it works fine. LinSSD version now is 2.7 and Ubuntu tells me that 2,7 already is the newest version . Since some update Linssd doesn't show any WiFi graph.

I need help in compiling LinSSID

2020-08-24T02:59:36.007000Z

Registered an account here so I could share what I learned. I've been a user of the Ubuntu family since I started using Linux, but now I am giving Fedora (KDE) a try, and LinSSID is the only thing thus far that I have not found a Fedora binary for that I had in Ubuntu.

In order to get this to compile on Fedora (32, currently), I installed the following packages:

qt5-qtbase-devel
qt5-qtsvg-devel
qwt-devel
boost-devel
qwt5-qt5-devel

when those are installed, enter this:
sudo ln -s /usr/lib64/libqwt-qt5.so.6 /usr/lib/libqwt-qt5.so.6

That will create a symbolic link from the Fedora location for the library (lib64) to where Ubuntu expects it (lib). This is correct as I write it now in August 2020, but if things change in the source code in the future, you will see an error message in the terminal window during the make phase below, and the file that it reports as not found will need to be linked rather than libqwt.qt5.so.6.

Make sure the archive file (.tar.gz) has been extracted, and in the terminal window, navigate to the location where the linssid.pro file is located.

Instead of entering qmake, use this:

qmake-qt5

That should finish nearly instantaneously. Then enter make as in the installation guide supplied with the source. If there are no error messages, and it just says that it left the directory, it should be good. Then enter sudo make installand it should be ready to use.

Added some additional features

Hi. Tnx for the tool.
Trying to install, but i get this error during make
"In file included from Getter.cpp:17:
MainForm.h:16:10: fatal error: qwt.h: File o directory non esistente
16 | #include <qwt.h></qwt.h>"

Thanks in advance

(Working on Ubuntu 20.04 LTS with linSSID already installed and ok)
