The compiler under Linux cannot find the header file
The problem arises:
If the header file cannot be found when compiling the program on Linux, the following error will be prompted:
$ gcc test.c -o test test.c:9:16: fatal error: xxx.h: No such file or directory #include<xxx.h>
The following description takes the Ubuntu system as an example.

The solution is as follows:
1. First find the path where xxx.h is located
The command is as follows:
$ sudo find / -name xxx.h
The result is as follows:
/usr/local/include/xxx/xxx.h
2. Then use the -I option to add the directory to compile
The command is as follows:
$ gcc test.c -o test -I /usr/local/include/xxx

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

There are three main ways to install software on Linux: 1. Use a package manager, such as apt, dnf or pacman, and then execute the install command after updating the source, such as sudoaptininstallcurl; 2. For .deb or .rpm files, use dpkg or rpm commands to install, and repair dependencies when needed; 3. Use snap or flatpak to install applications across platforms, such as sudosnapinstall software name, which is suitable for users who are pursuing version updates. It is recommended to use the system's own package manager for better compatibility and performance.

Linux is suitable for old hardware, has high security and is customizable, but has weak software compatibility; Windows software is rich and easy to use, but has high resource utilization. 1. In terms of performance, Linux is lightweight and efficient, suitable for old devices; Windows has high hardware requirements. 2. In terms of software, Windows has wider compatibility, especially professional tools and games; Linux needs to use tools to run some software. 3. In terms of security, Linux permission management is stricter and updates are convenient; although Windows is protected, it is still vulnerable to attacks. 4. In terms of difficulty of use, the Linux learning curve is steep; Windows operation is intuitive. Choose according to requirements: choose Linux with performance and security, and choose Windows with compatibility and ease of use.

Install Git: Install Git through the package manager on the server and verify the version; 2. Create a dedicated Git user: Use adduser to create a git user and optionally restrict its shell access; 3. Configure developer SSH access: Set the .ssh directory and authorized_keys file for git users, and add the developer's public key; 4. Create a bare repository: Initialize the bare repository on the server and set correct ownership; 5. Client cloning and push: Developer cloning the repository through SSH, submit changes and successfully push code to complete the construction of a private Git server.
