Introduction: In the previous articles, we have basically understood how to link a third-party library. This article and the next will supplement two methods for detecting external libraries. So far, we have learned two methods for detecting external dependencies: Using the built-in CMake find-module, but not all packages can be found in the CMake find … Read more
Have you ever encountered a situation like this: A .c file includes another .h header file, using a Makefile to build (compile) the application. The first time you compile and execute, everything works fine! However, if you modify the .h header file and try to compile again, issues arise: The expected execution flow is: make … Read more
Building Ansible Execution Environment Images The construction of Ansible’s execution environment is essentially the construction of a container image, with Ansible providing a command <span>ansible-builder</span> to achieve standardized image building. <span>ansible-builder</span> will by default use the <span>execution-environment.yaml</span> or <span>execution-environment.yml</span> in the current directory as the execution environment definition file (which is the <span>Containerfile</span> or <span>Dockerfile</span>). … Read more

1. Background When compiling C/C++ projects, you may sometimes see .d files, but it may not be clear how they are generated. First, how does Makefile handle header file dependencies? Typically, in a Makefile, we need to specify which source files (.c or .cpp) and header files (.h) the target files (like .o) depend on. … Read more
Compiled languages require compilation before execution. This is seen as an advantage by some, as it allows for syntax checks and other information verification during the compilation process, helping to avoid basic errors. Additionally, the compiled code can run faster. However, others view this as a disaster. Often, this is not due to any other … Read more
When compiling a large project, there are often many target files, library files, header files, and the final executable file. There are dependencies between different files. For example, when we compile using the following commands: $gcc -c -o test.o test.c $gcc -o helloworld test.o The executable file helloworld depends on test.o for compilation, while test.o … Read more
Some applications can only be installed from source code. Here’s how to do it. Translated from Linux: How To Install Apps From the Source by Jack Wallen. When I first started using Linux, there was only one way to install applications… from the original source code. Those days are long gone, and now there are … Read more
