goldendict: error while loading shared libraries: libQt5Svg.so.5

In Ubuntu system, use the tool goldendict

goldendict: error while loading shared libraries: libQt5Svg.so.5: cannot open shared object file: No such file or directory

The reason is that the environment variable is not set. Solution:

1 find the libqt5svg. So. 5 path./opt/Netease/Netease cloud music/LIBS/libqt5svg. So. 5

2/etc/LD. So. Conf.d add a file goldendict.conf, which reads as follows
/opt/Netease/Netease cloud music/LIBS

3 execute the command to update the dynamic link library sudo ldconfig

The following is the reference address:

Unity report error CS0619: ‘XRDevice.isPresent’ is obsolete

Unity error resolution error cs0619: ‘xrdevice. Ispresent’ is obsolete:

1. Problem description 2. Solution

1. Problem description

Assets\Battlehub\RTCommon\Scripts\RTEBase.cs(690,20): error CS0619: ‘XRDevice.isPresent’ is obsolete: ‘This is obsolete, and should no longer be used. Instead, find the active XRDisplaySubsystem and check that the running property is true (for details, see XRDevice.isPresent documentation).’

This error occurred when I was using unity’s runtimes editor plug-in, which probably means that the API has expired and needs to be modified.


2. Solutions

I checked the Internet and found no relevant information, so I went directly to unity’s API document according to the error message. After looking at it, I know that the previous interface can’t be used. Just rewrite it. Xrdevice.ispresent document. Just rewrite an inner class and call it again according to the document
add the following part to the code, and then modify the calling code.

internal static class ExampleUtil
{
    public static bool isPresent()
    {
        var xrDisplaySubsystems = new List<XRDisplaySubsystem>();
        SubsystemManager.GetInstances<XRDisplaySubsystem>(xrDisplaySubsystems);
        foreach (var xrDisplay in xrDisplaySubsystems)
        {
            if (xrDisplay.running)
            {
                return true;
            }
        }
        return false;
    }
}

Error: l6218e: undefined symbol appears when keil calls lib

1. Recently, when using MDK to generate lib, Keil failed to call lib, resulting in a lot of undefined problems

2. When generating lib with keil for testing, you can’t add the header file to the project.

        Delete all. H files, regenerate the Lib file, and call again. It is found that there will be no more problems such as error: l6218e: undefined symbol

Some error occurred error: listen eaddinuse: address already in use 127.0.0.1:3000

In this case, the port is occupied
solution:
window + R open run input CMD open DOS command window

Input: netstat - ano view port

the red mark indicates that the port is occupied,

Enter the TCP number corresponding to taskkill/F/T/im in CMD to turn off the occupied port
and then NPM run serve can be run normally

Rstido’s default link cache is 131072 bytes. After conversion, it is 131kb, 0.131mb

  But the size of the data you downloaded & gt; 131072 bytes, so we need to adjust the default connection cache for normal download
