Click the blue text to follow the author 1. Introduction CMake is a cross-platform open-source build system generator. It does not directly build software but generates a build system for a specific platform based on the descriptions in the <span>CMakeLists.txt</span> file. The role of CMake is to decouple the build process from the compiler, operating … Read more
• OpenWRT’s opkg supports most software packages, but some specific domain packages still require source installation, such as the SRS server (streaming media server). Source programming typically requires CMake. This article attempts to compile and install CMake from source in OpenWRT system based on Host mode, summarizing the problems encountered and their solutions as follows. … Read more
First, install gcc-g++ and cmake. Taking CentOS as an example: yum install gcc-c++ yum install cmake First, create a main.cpp file that includes a main function, and create a CMakeLists.txt file. The purpose of the CMakeLists.txt file is to guide CMake in compiling the C++ program on the current operating system. main.cpp #include <iostream> int … Read more
From WeChat Official Account: One Linux Introduction to Make: Make is an engineering manager, which, as the name suggests, is used to manage a large number of files. The Make engineering manager is essentially an “automatic compilation manager“. The term “automatic” refers to its ability to automatically discover updated files based on file timestamps, thereby … Read more
BitBake is a powerful build tool primarily used for building embedded Linux systems, playing a core role in the Yocto Project. It is not just a simple build tool but a complete task execution engine capable of handling complex dependencies and build processes. Basic Concepts BitBake uses specific configuration files (.bb files) to describe how … Read more
Using CMake: A C++ Project Build Tool CMake is a popular cross-platform build system that generates standardized build files, allowing C++ projects to be easily compiled and managed across different operating systems and development environments. In this article, we will introduce the basic usage of CMake and how to use it to create a simple … Read more
1. Why Use CMake? In C++ projects, manually managing the build chain (especially for large projects with multiple platforms and modules) can introduce significant complexity. CMake addresses the following issues with its declarative syntax: Cross-platform builds: Generates build files for the corresponding platform (Makefile/MSVC project/Xcode project) Dependency management: Automatically finds third-party libraries (such as OpenCV, … Read more
Introduction to CMakeLists<span>CMakeLists.txt</span> file is the input file for the CMake build system used to build software packages. Any package that conforms to the CMake specification contains one or more <span>CMakeLists.txt</span> files that describe how to build the code and where to install it. The <span>CMakeLists.txt</span> file used for catkin projects is a standard CMakeLists.txt … Read more
Word count: 7897, approximately 40 minutes of reading time Comprehensive Guide to CMakeLists (Part 1) 0. CMake Application Examples Previously, we organized content on using CMake to introduce third-party libraries (header file directories, library directories, library files). However, the content organized here is not complete. Therefore, we need to further organize the usage of CMake … Read more
