Master the Core Logic of Library Building from Compilation Principles to Industrial Practices 1. Essential Differences Between Static and Dynamic Libraries Core Feature Comparison Feature Static Library (<span>.a</span>/<span>.lib</span>) Dynamic Library (<span>.so</span>/<span>.dll</span>) Linking Method Compiled into the executable file at build time Loaded dynamically at runtime Memory Usage Multiple loads of the same library will consume … Read more
1. Generate a static library for third-party useIn Linux, the name of a static library is composed of: lib + library name + .a, where the library name needs to be specified, and lib and .a are generated automatically. The Windows system is similar.Project file structure:CMakeLists.txt # Set the minimum required CMake version to 3.15 … Read more
Methods for Python to Call C/C++ Programs Recently, while debugging, I encountered a situation where Python was running very slowly, so I researched methods to embed C++ programs in Python. I am documenting this for future reference. Generally, calling C/C++ programs from Python can be divided into three steps: 1. Write the C/C++ implementation program. … Read more
1. Task Explain the process of building static and dynamic libraries with CMake in a simple and understandable way using examples. Tasks: Create a static library and a dynamic library, providing the HelloFunc function for use in other programs, which outputs the string ‘Hello World!’ to the terminal.

1. Introduction For development on Windows, many IDEs come with integrated compilers, such as Visual Studio, providing a “one-click compile” feature. After coding, you only need one operation to compile, link, and generate the target file. Linux development is different from Windows; typically, the gcc/g++ compiler is used on Linux. If you are developing Linux … Read more
