[Solved] Doris 5 Doris_core Run make Error: bk_messages.hh:214:26 error: invalid conversion from ‘char‘ …

Doris 5 error during installation

Problem Description:

Doris in Doris 5_ Error when executing make in the core folder: BK_ messages.hh:214:26 error: invalid conversion from ‘char’ to ‘const char*’ [fpermissive]

strcat(name_, ‘\ 0’);// terminate id

Solution:

Find Doris_ BK in the core folder_ Message.hh file, comment out line 214 strcat (name, '\ 0');, add name_[ 9] = '\0';

It should be changed as follows:

211   if (strlen(id)>=10)
212      {
213       strncpy(name_,id,9);
#         strcat(name_,'\0');
214       name_[9] = '\0':
215      }
216    else
217      {

reason

The reason is to get the system default DM_ Svc.conf configuration file failed. According to the error prompt of the console, we can find the following method to get the DM of different systems_ SVC. Conf configuration file.

if filePath == "" {
    switch runtime.GOOS {
        case "windows":
	    filePath = os.Getenv("SystemRoot") + "\\system32\\dm_svc.conf"
        case "linux":
	    filePath = "/etc/dm_svc.conf"
        default:
	    return
    }
}

According to the default file path of windows system, find DM_ Open the SVC. Conf configuration file and find the following

TIME_ZONE=(480)
LANGUAGE=(cn)

Solution

Creating DM in /etc path of Linux virtual machine_ SVC. Conf configuration file, the content of which is similar to the OS. Getenv ("systemroot") + "\ \ system32 \ \ DM of windows_ SVC. Conf " DM under Path_ SVC. Conf configuration file can be consistent

Cannot find module ‘.. / lib / utils / unsupported. JS’ problem in installing node in centos7

When installing node in centos7 virtual machine, an error is reported: cannot find module ‘…/lib/utils/unsupported. JS’. The complete error is as follows:

the prompt is that an unsupported.js file cannot be found. Finally, it is found that the soft connection is wrong when installing this version of node in centos7, This problem may not be solved by re installation (at present, I only encounter this problem in the virtual machine of centos7). Delete the original NPM connection and re create one.

1. First, download the CD to the bin folder of the node version, where version 12.16.2 is installed

cd /opt/node-v12.16.2-linux-x64/bin

2. Delete the NPM file in the path, and enter yes when prompted

rm npm

3. Reestablish file connection

ln -s ../lib/node_modules/npm/bin/npm-cli.js ./npm

Using NPM – V command again, it is found that it is almost OK.
the whole operation is shown as follows:

ERROR bag unindexed: 2021-6-23-0103all.bag. Run rosbag reindex.

1. Problem
if you want to run a. Bag file that hasn’t been used for a long time, run the command: rosbag info XXX. Bag , and find an error, as follows:

ERROR bag unindexed: 2021-6-23-0103all.bag.  Run rosbag reindex.

If you want to play it by force: rosbag play XXX. Bag , you can’t either. The error is as follows:

 [ INFO] [1624972506.447439941]: Opening 2021-6-23-0103all.bag
[FATAL] [1624972506.448068825]: Error reading from file: wanted 4 bytes, read 0 bytes

2. Solution
according to the error prompt, enter the command:

rosbag reindex xxx.bag

Two. Bag files will be generated, as follows:

in the picture, xx.orig.bag is the first package, and xxx.bag is the package after reindex.
finally, enter the command: rosbag info XXX. Bag to output normally, as follows:

Schema validation error in conig/config.xml. See the log for detais, Schema validation can be……

The problem of config.xml when Weblogic gives an error prompt when activating changes is related to the parameter dweblogic. Configuration. Schemavidationenabled = false

terms of settlement:

You need to add this parameter to the startweblogic. Sh file

The path is: install path/xdomain/bin           Modify startweblogic. SH in the directory as shown in the figure below

Then restart

If it is clustered, each server should be configured and then started. Otherwise, the same problem may occur

terms of settlement:

Just run the following three instructions

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

There is another solution in the original, but I solved it with the first one. If you can’t solve it with this method, you can try the second one in the original https://blog.csdn.net/weixin_ 45621658/article/details/110734514

It looks like you are upgrading from Neo4j 2.x. Many configuration
changes and improvements have been made in 3.0, including the location of
the databases. These changes cannot be handled automatically by this package
installation.

You will need to upgrade from Neo4j 2.x to Neo4j 3.2 and THEN to this release.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Here I want to install neo4j_ 1%3a3.5.14_ All.deb, but I already have neo4j 2. X. I need to upgrade from neo4j 2. X to neo4j 3.2, and then to this version
the following error report also means to analyze neo4j_ 1%3a3.5.14_ Error in all.deb
(but I didn’t look at the above information carefully, so I only know that the following error report says my neo4j_ 1%3a3.5.14_ All.deb parsing error)

I’ve checked a lot of blogs here, but it doesn’t work for a long time
I followed the method in reference 1. Method 1 and method 2 are useless. I have achieved method 3
the process of trying method 3 is as follows:

$ sudo rm /var/cache/apt/archives/neo4j_1%3a3.5.14_all.deb

The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

When you run sudo apt get autoremove , you will be prompted

The following packages have unmet dependencies:
 cypher-shell : Breaks: neo4j (< 3.1.4) but 2.1.5 is installed

At this time, I realized that there is a 2.1.5 version of neo4j in my system
if this step is not successful, the following instructions will not be executed successfully.

Here, I query the directory of neo4j version 2.1.5 through the where is command, and modify the corresponding directory name. It is reasonable to say that after the modification, the system cannot find neo4j2.1.5, sudo apt get autoremove should be able to execute successfully. But it didn’t.

In fact, it’s very simple here. We just need to uninstall neo4j in version 2.1.5. As follows:
perform sudo apt get remove neo4j uninstall
then follow method 3 in reference blog 1 to execute it again. The above error will not be reported in the process.

Then apt and apt get can be used normally.

Stack overflow and CSDN, you can see all kinds of things

Some say that virtual environment must be used, but I don’t believe it;

Some people say that you must use native Python environment (not Anaconda or other integrated environment), but I don’t believe it;

Some people say that it may be caused by the too low and too high version of Python;

Some people say that maybe your version of pyinstaler is too high. Let’s have a try. I believe it;

#The following error occurred

#It is suspected that the temporary file in the original build interferes with the new build. After deleting the temporary file, it continues to build, and the same error still exists;

Solution

#Check on stack overflow and CSDN. There are all kinds of things to say. Finally, we adopted the method of reducing the version and succeeded

#   pip install pyinstaller==3.5
