Qt_5 not defined in file libQt5Core.so.5 with link time reference

Post by tommywright » Fri Mar 29, 2019 7:20 pm

I hate to ask because it’s usually simple but I can’t seem to find the solution to this. I see many people with software pointing to the wrong lib but their solutions look so particular to their issue and so far none of their solutions have worked for me.

Here’s my error when trying to run fs-uae-launcher.

ImportError: /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: symbol _ZNK11QLocaleData13validateCharsERK7QStringNS_10NumberModeEP10QByteArrayi6QFlagsIN7QLocale12NumberOptionEE version Qt_5 not defined in file libQt5Core.so.5 with link time reference

Given the lack of information provided in your question the answer has to be equally anemic: You installed something incompatible with your operating system.

Sorry, it’s all the information that I have. I installed a program called fs-uae-launcher and when I try to run it from a terminal «fs-uae-launcher», it gives me that error.. here, I’ll copy the entire output here.

It would help to know more about your system setup. If you run » inxi -Fxzd » and » lsusb » from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.

This FS-UAE Amiga Emulator application may already be in the «Synaptic Package Manager (SPM)» and it has various Linux installation options from their website including a Linux archive file and a PPA. There are other Amiga and game emulators in the «Synaptic Package Manager (SPM)» as well.

This came up perfectly on my system without any errors from their extracted archive file, in their folder using the command below to start their script file.
Download FS-UAE | FS-UAE Amiga Emulator

From my Downloads folder in their folder
~/Downloads/fs-uae-portable-suite_2.8.3_linux_x86-64$ ./Launcher

sudo apt install qt5-default

The version from the repos installs without a hitch (if you didn’t mess up your Qt5 libs), so I wouldn’t necessarily advise to load more third-party packages onto the system. It can only get worse.

Thanks for the help guys.. yeah, I should have said that it’s not an issue with fs-uae. I have that installed just fine on two other computers (one of them running Linux Mint even).

How can I use my local time as the only reference of `ntpd`?

I want to let my Linux device synchronize its local time with the local time of another Linux server without any other references. I don’t care about the actual time. I want my fake time. Therefore I don’t need any other ntp servers for reference. For example I just set the local time of my Linux server 1.2.3.4 to 2033-02-23 15:23:10 . I want to let my Linux device synchronize this time. The config file /etc/ntp.conf on the Linux server is:

restrict 127.0.0.1 restrict ::1 server 127.127.1.1 fudge 127.127.1.1 stratum 8 disable monitor logfile /var/log/ntp/ntp.log pidfile /var/run/ntpd.pid driftfile /var/lib/ntp/drift leapfile /etc/ntp.leapseconds
