  :632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library

  'cvShowImage'

Aborted (core dumped)

Error resolution

Execute the command according to the solution given by the system

sudo apt-get install libgtk2.0-dev
sudo apt-get install pkg-config

It doesn’t solve the problem

Cause of problem

The problem is that there is a problem with the compilation configuration when installing opencv
I execute cmake…
and the correct command is

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

Solution:

Locate the folder where opencv is installed

cd /home/chen/Downloads/opencv-3.4.3
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
sudo make
sudo make install

[vite] http proxy error: Error: self signed certificate in certificate chain vite

In order to prevent cross domain problems when requesting interfaces, vite proxy is used for configuration.

For example, the address of the request interface is https://172.1.1.0:8080 , the vite configuration information is as follows:

...

server: {
        host: '0.0.0.0',
        port: 12000,
        proxy: {
            '/local/': {
                target: 'https://172.1.1.0:8080',
                changeOrigin: true,
                rewrite: (path) => path.replace(/^\/local\//, ''),
            },
        },
},

...

Local requests are all interfaces. You only need to add a prefix -/local /. For example, the login interface is’/local/Login ‘.

So I went to request and found that the error was reported directly. The error information is as follows:

[vite] http proxy error: Error: self signed certificate

The certificate is wrong.

Solution: add a configuration – secure: false The overall configuration code is as follows:

proxy: {
            '/local/': {
                target: '',
                

                // Add
                secure: false,
                // End




                changeOrigin: true,
                rewrite: (path) => path.replace(/^\/local\//, ''),
            },
        },

Then try again. Sure enough, there’s no problem.

[Solved] swagger Error: Fetch errorInternal Server Error /swagger/v1/swagger.jso

When using swagger as API interface document, the following error often occurs

If this error occurs, you can take a closer look at the console,

As can be seen from the figure, ambiguous HTTP method for action is an ambiguous HTTP operation method

Check the corresponding controller and you can see that the operation feature [httppost] or [httpget] is not added. If it is added, it will be OK.

[Solved] Fatal error C1083: unable to open include file: ‘d3dx9.h’

1. First confirm in the control panel whether to install Microsoft DirectX SDK (June 2010), if no you can go to https://www.microsoft.com/en-us/download/details.aspx?id=6812 to download.

After installation d3dx9.h file in: D:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include

2. Set the path.

[Solved] MacOS Compile ffmpeg Error: ERROR: openssl not found

On a whim today, I suddenly want to start studying the source code of ffmpeg. After downloading all the dependent libraries, I use the command configure

appear. Error: an error is reported when OpenSSL is not found. The version of OpenSSL I use is

Then the solution is seen from here

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

After writing, configure succeeded!

If you encounter some other problems, such as the following, you only need to delete the corresponding file and reconfigure it

In this case, I can’t wait all the time. I waited for a while and didn’t initialize well…

Solution

Because it is a new cluster, there is no useful data. You can clear the metadata in the following way to reinitialize. Before clearing metadata, close HBase components in USDP’s Web UI.

Delete ZK’s metadata

Since part of the metadata of HBase is stored on zookeeper, so you should so this as below:

HDFS metadata deletion

Since part of HBase data is stored in HDFS, it is also necessary to delete the metadata stored in HDFS by HBase. Since USDP has Ranger and actually has users and permissions, you can’t use root to delete important data of HDFS. You must switch to Hadoop user first.

[rospack] Error: no such package beginner_tutorials

[rospack] Error: no such package beginner_tutorials
I found this error during the process, and after pouring in the path, I couldn’t solve it, so I checked the workspace and found the beginner_tutorials file, so the problem is in the execution

catkin_create_pkg beginner_tutorials std_msgs rospy roscpp

The CD is not inside the src.
So if you find this problem, you can check the location of beginner_tutorials.
Solution: Just delete the beginner_tutorials and re-execute it.

[Solved] error: Pulling is not possible because you have unmerged files

Scene

For the same repository, Jane and Flora each pulled code from the master branch of the repository.
Jane commits the modified code to the master branch first.
Flora then commits the modified code to the master branch, and finds that the remote repository master branch code has changed due to Jane’s commit, which prompts “Updates were rejected because the tip of your current branch is behind” when committing. branch is behind”

When Flora tried to pull the master branch code for merging, it prompted “error: Pulling is not possible because you have unmerged files”

Solution:

git add -u 
git commit -m "xxxx" 
git pull
git push

First, the file will be stored in the staging area and then commit the comments, and then git pull will not report an error
This kind of error is generally thought to have a conflict file, need to resolve the conflict or merge files, after the solution or merge need to recommit, not limited to pulling

[Solved] Swagger Error: Whitelabel Error Page status=405

The swagger link is accessed with the following error

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Thu Mar 17 20:14:30 CST 2022
There was an unexpected error (type=Method Not Allowed, status=405).
Request method ‘GET’ not supported

The reason is that @PostMapping does not have a configured path

   @PostMapping
    public UserInfoResponse queryUserNameById(@RequestBody UserInfoRequest request){
        log.info("Query user name request parameters",request);
        UserInfoResponse response = userService.selectUserNameById(request);
        log.info("Query user name return parameters",request);
        return response;
    }

[Solved] QT Icon Set Error: error: [release/helloworld_resource_res.o] Error 1

When learning QT setting icons for beginners, errors are reported during compilation. The following two error correction methods and correct correction methods are shared.

Error operation 1: modify the suffix of JPG file to .ico

Error operation 2: save as using PS and other tools on BMP format and then modify the suffix to .ico format

Correct operation: generate transparent ICO icons online through ICO, and then import them

Tips: the default size of qtball is 32 * 32, and the menu is 16 * 16

If the icon size is larger than the default size, QT will automatically reduce the size; If the icon size is smaller than the default size, QT will not operate.

.ico files need to be placed in the project resource directory.

Compiled, as shown below.
