Failed to open PetaLinux lib: librdi_commonxillic.so: cannot open shared object file: No such file or directory.

Solution:

sudo echo "/opt/pkg/petalinux/2018.3/tools/lib" > /etc/ld.so.conf.d/petalinux.so.conf
sudo ldconfig

Extended content:

Solution to ‘cannot open shared object file’ (Linux ):

1. Prompt when calling the dynamic library .so file in Linux:

cannot open shared object file: No such file or directory

Solution:

1. At this time, enter ldd xxx to check which libraries are missing

libmysqlcppconn.so.7 => not found
libboost_system.so.1.64.0 => not found

2. Set variable LD_LIBRARY_PATH

sudo gedit ~/.bashrc

Add on the last line:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/path

Re-open bash and then ldd to find the library path.

2. (Recommended) Modify the shared library configuration file /etc/ld.so.conf
/etc/ld.so.conf
1. Setting:

sudo gedit /etc/ld.so.conf

2. Add library path:

include /etc/ld.so.conf.d/*.conf
/home/xxx/Documents/core/Linux/Test/src/Test

Save and exit
3. Make the configuration effective immediately

sudo ldconfig

ERROR: Failed to build project

Solution:

1) File Directory <petalinux_proj>/project-spec/meta-user/recipes-bsp/fsbl/fsbl_%.bbappend

Check whether there is fsbl_% Bbappend or not, create it if not:

vim <plnx-proj-root>/project-spec/meta-user/recipes-bsp/fsbl/fsbl_%.bbappend

2) Add the following

do_compile_prepend(){

   install -m 0644 ${TOPDIR}/../project-spec/hw-description/psu_init.c ${B}/fsbl/psu_init.c

   install -m 0644 ${TOPDIR}/../project-spec/hw-description/psu_init.h ${B}/fsbl/psu_init.h

}

3) Clean up and rebuild the fsbl file

$ petalinux-build -c fsbl -x cleanall

$ petalinux-build -c fsbl

[Solved] Ubuntu Compile Rust Program Error: failed to run custom build command for openssl-sys v0.9.39

Compiling Rust program in Ubuntu environment reports an error:

failed to run custom build command for openssl sys v0.9.39

Ubuntu version: 20.04

Refer to GitHub’s discussion and there are two possible solutions:

  1. sudo apt install pkg-config
  2. sudo apt install libssl-dev

I use the second method to solve this problem.

[Solved] Linux error E: dpkg is broken, you must manually run ‘sudo dpkg –configure -a’ to resolve this issue

Executes the Linux commandsudo apt install curland reports an error:

E: dpkg is interrupted. You must manually run ‘sudo dpkg — configure – a’ to solve this problem

System version: Ubuntu 20.04 LTS

Solution: three-step command line

sudo rm /var/lib/dpkg/updates/*
sudo apt-get update
sudo apt-get upgrade

PHP php-config is not installed error in ubuntu 16 [How to Solve]

Environment

Ubuntu 16.04.1 LTSPHP 7.0.33

Question

When compiling and installing php extensions with php config, it is found that php-config does not exist.

Check whether php-config exists or not?

$ whereis php-config
php-config:

As above, it returns null, indicating that it does not exist.

Solution:

This problem occurs because the php-dev package is not installed. You can install it once.

Install php-dev

$ apt-get install php-dev

If php5 is version, run apt-get install php5-dev.

re-check php-config

$ whereis php-config
php-config: /usr/bin/php-config /usr/bin/php-config7.0 /usr/share/man/man1/php-config.1.gz

As shown above, the installation is successful.

VScode Error: extension failed XHR Failed (Ubuntu Virtual Machine)

Leave a reply

In the process of learning Linux embedded development, I encountered the following problems: after installing VS code in the Ubuntu virtual machine, it need to install appropriate plug-ins. At this point, vscode fails to expand XHR Failed, as shown in the figure:

And press the F1 key inside Vs code to open Developer:Toggle Developer Tools, enter the Console to query the reason, The error shown in the figure below appears (That is, Ubuntu system will point the domain name to the specified IP solve this problem):

After searching the Internet for many solutions, the following operations can solve the problem:

1. Open the hosts file in the Ubuntu terminal

sudo gedit /etc/hosts

2. Add the corresponding relationship between IP and domain name in the file as follows, and save the hosts file：

13.107.42.18 marketplace.visualstudio.com

3. Restart Ubuntu.

[Solved] Error occurred during initialization of VM javalangNoClassDefFoundError javalangObject

When you run java/javac/java -version under the doc command, an error was reported:

Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Object

 

Or eclipse cannot be opened for this reason

I summarized the following three reasons:

1: java environment variables are misconfigured, check the right and wrong environment variables, especially check the classpath

General (in the case of java configuration only), the value of the environment variable

JAVA_HOME ========= “your jdk installation directory” such as “C:Program FilesJavajdk1.8.0_121”

Path ========= “%JAVA_HOME%in;%JAVA_HOME%jrein”

CLASS_PATH ========= “%JAVA_HOME%libdt.jar;%JAVA_HOME%lib ools.jar”

2: If there is no problem with the environment variable configuration, then go to the jdk installation directory (such as C:Program FilesJavajdk1.8.0_121) and look for tools.jar under lib and rt.jar under jrelib to see if they exist, it is possible that rt.pack and tools.pack exist.

At this point, just unpack the corresponding files into rt.jar and tools.jar, and you can use the unpack200 tool inside the bin

#cd /usr/java/j2sdk1.4.2/lib
#unpack tools.pack tools.jar
#cd …/jre/lib
#…/…/unpack rt.pack rt.jar

3: There is no tools.jar under lib or rt.jar under jrelib, or there are missing files under lib or jrelib (40 files), so just copy them from elsewhere.

If you run java command after copying tools.jar or rt.jar, there may be missing files under jrelib, look carefully or just copy a whole jrelib, it can be solved.

How to Solve labelme Install Error in Ubuntu

Create a labelme environment using a virtual environment:

According to the official guidelines, link: GitHub – wkentaro/label: image polygon annotation with python (polygon, rectangle, circle, line, point and image level flag annotation)

conda create --name=labelme python=3
source activate labelme
pip install labelme

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Relevant dependent libraries need to be installed:

sudo apt-get update
sudo apt-get install libfreetype6-dev
sudo apt-get install pkg-config
sudo apt-get install libpng12-dev
sudo apt-get install pkg-config

Error 2 encountered:

I guess the python version is too high, so I recreated the virtual environment with pyhton = 3.9

conda create --prefix=/home/fxp/envs/labelme python=3.9 -y

The final installation is successful;
