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

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

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.
