[Solved] GLSL Lint: Failed to spawn ‘glslangValidator‘ binary. Error: spawn glslangValidator.exe ENOENT

1. preface

After using vscode to install the plug-in: glsl lint, there is an error every time you start vscode:
glsl lint: failed to spawn ‘glslangvalidator’ binary Error: spawn glslangValidator. Exe enoent
and vscode will not be automatically colored and highlighted every time the shader program is opened. At this time, I reinstall the glsl lint plug-in. It’s troublesome

glslangValidator is a custom GLSL reference compiler from the Khronos Group, the official OpenGL standard customizer. The command line compilation mode facilitates users to test glsl syntax directly and bypass the C/C++ related dependency libraries compilation, and there is no need to write a lot of initialization code in the main file. This can save a lot of time in practical testing. In many websites such as shadertoy, the glsl code written by users can be compiled and run directly in the main function, which requires a convenient syntax check, and the shadertoy website also provides a simple syntax check. However, glslang is a standard custom official compiler, so the compiled glsl code can be compiled correctly on all kinds of drivers that support GLSL syntax.

2. Solution steps

1. Open vscode settings

2. Search “security.workspace.trust”

Enter “security.workspace.trust” in “search settings” (just enter “security”)

3. Cancel ssecurity.workspace.trust：Enabled

Remove the hook in front of “security.workspace.trust：Enabled”

Just restart vscode

After checking, it is generally caused by the incompatibility between Ceres-solver and eigen3. You can’t use the latest version of Ceres when running vins-mono.

I had no choice but to uninstall the previous version 2.0.0 first.

sudo rm -r /usr/local/lib/cmake/Ceres
sudo rm -rf /usr/local/include/ceres /usr/local/lib/libceres.a
sudo rm -r /usr/local/share/Ceres

Then download version 1.14.0 here,

http://ceres-solver.org/ceres-solver-1.14.0.tar.gz

wget ceres-solver.org/ceres-solver-1.14.0.tar.gz
https://ceres-solver.googlesource.com/ceres-solver
cd ceres-solver-1.14.0
mkdir build
cd build
cmake ..
make -j4
make test
sudo make install

Compile ceres_curve_fiiting
CD to ceres_curve_fiiting folder

 mkdir build
 cd build
 cmake ..
 make
 ./curve_fitting

Compilation finished!

[Solved] Error contacting service. It is probably not running.

First, check whether more than half of the servers start zookeeper. If yes, use the JPS command and find that the quorumpeermain main class is not started

[atguigu@Hadoop103 zookeeper-3.5.7]$ jps
14850 Jps

The most likely cause: Zookeeper decompression path in the conf folder zoo.cfg (I am here after changing the name) configuration when adding content after the addition of spaces and the creation of myid up and down there are empty lines or left and right spaces, enter the file deleted, and then check the jps

[Solved] npm Error: Error: Cannot find module ‘postcss-loader‘

1. Problem
an error is reported when executing the command NPM run serve:

Error: Cannot find module 'postcss-loader'

2. Solution

The most thorough solution is to uninstall the current nodejs version and install the nodejs version consistent with the module version.

If you don’t want to reinstall nodejs, you can use the following methods:
install module:

npm install postcss-loader

If you continue to report errors:

npm ERR! Could not resolve dependency:
npm ERR! postcss-loader@"*" from the root project
npm ERR!
npm ERR! Conflicting peer dependency: [email protected]
npm ERR! node_modules/webpack

npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps

[Solved] GBase 8a V95 Replace Node Error: single vc mode does not support ‘–freenode’

The v95 version of gbase 8A supports fast replacement of failed nodes through free nodes (omitting the need to find the installation package and check the installation and configuration process). However, free node is only for the scene with VC enabled. For single VC, that is, the mode compatible with V8 version, free node is not supported, so it does not support this node replacement method. The solution is to use a new node.

Error message
version: 9.5.3.22

install prefix: /opt/gbase/10.0.2.103
execute replace node os user: gbase

Error: replace.py(line 1147) -- single vc mode does not support '--freenode'
[gbase@gbase_rh7_003 gcinstall]$

Reason
the cluster is in single VC mode, compatible with V8, and does not support freenode. Look at the bottom of the gcadmin output. There is really no freenode information.
