Day 66: ABI Compatibility in C Language In the previous lecture, we analyzed the issues and best practices of dynamic loading libraries (such as dlopen), including the dynamic loading process, common pitfalls, and safe coding paradigms. 1. Step-by-step Explanation of the Theme Principles and Details ABI (Application Binary Interface) determines how different binary modules (such … Read more
In my personal experience, in most cases, GDB debugging can be used to debug the behavior of a specific dynamic library independently. This allows for convenient problem localization directly on the device where the anomaly occurs. This article introduces how to use GDB to locate issues for a single dynamic library on a production device. … Read more

To facilitate the later upgrade and expansion of program functions, dynamic libraries are often used in program design. This way, the subprogram only loads the dynamic library and uses the functions within it at runtime. Therefore, we usually only need to update the DLL (for Windows systems) or SO (for Linux systems) files to achieve … Read more

Click the blue textFollow the author 1. Introduction In slightly more complex projects, we often encounter situations where we need to build multiple executable files, each potentially composed of different source files. More commonly, the project’s source code is distributed across multiple subdirectories rather than being concentrated in a single directory. ProjectRoot ├── CMakeLists.txt (Top-level … Read more
When compiling a new program, we will use third-party compiled library files or library files that we compiled ourselves. Here we will use the static and dynamic libraries that have been compiled previously.1. Using Static LibrariesThe file structure is as follows. Here we have deleted add.c and subtract.c from the src folder, keeping only main.c, … Read more
