Introduction: Why Do We Need Makefile? In Windows IDEs, we can simply click the “Build” button to complete the compilation, but behind large projects often lies complex build logic. Makefile is the core tool for achieving automated builds in Linux/Unix environments, acting like a precise conductor that coordinates: Optimization of compilation order Incremental compilation (only … Read more
Overview In this project, we encountered a need for Optical Character Recognition (OCR). However, the best-performing <span>PaddleOCR</span> can only run on Baidu’s <span>PaddlePaddle</span> framework. In common projects, the more widely used Pytorch framework is often preferred. Installing PaddlePaddle separately not only makes the project overly bulky but may also lead to conflicts. In the previous … Read more
In the process of building embedded Linux systems, the “capability to handle package dependencies” is one of the core indicators of the maturity of a build system. Today, we will focus on a detailed topic — how Buildroot and Yocto handle package dependencies? What are their respective advantages and disadvantages? This not only concerns build … Read more
Late at night, a user suddenly reached out for help, saying that the system on the 64G TF card of the Jetson Xavier NX development kit we provided suddenly could not access the graphical interface. This user is a new user who just bought the NX development kit, and I can almost imagine their panic… … Read more
Have you ever encountered these frustrating moments? – Project A requires <span><span>Python 3.7</span></span>, but Project B can only use <span><span>Python 3.10</span></span>, frequently switching versions leads to confusion; – Code that runs perfectly on your local machine throws errors on another computer due to incompatible dependency versions; – When installing a new package, accidentally overwriting critical … Read more
1. Brief Introduction This article will delve into the Python dependency management tool Poetry and provide a comprehensive comparison with the traditional pip. Dependency management is a critical aspect of Python project development, and a good dependency management tool can effectively resolve issues such as version conflicts, environment isolation, and project packaging and deployment. Whether … Read more
Review: Why do we use Make and CMake tools? The main reasons are to automate the build process, manage dependencies, and simplify cross-platform development for complex project compilation requirements: Large C++ projects often consist of multiple source files, header files, and library dependencies, making manual compilation commands (like <span>g++</span>) error-prone and inefficient. Dependency Management: Build … Read more
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
Hello everyone! Today, I will guide you through implementing one of the most important features in Excel using C++—the cell reference system. 1. Basic Characteristics of Excel Cell References Excel cell references mainly have three characteristics: Coordinate Representation: Row and column identifiers like A1, B2 Relative/Absolute References: Mixed references like 1 or A$1 Range References: … Read more
1Building Systems:The Migration Costs of the Warring States Period Fragmentation of Multiple Tools CMake/Bazel/Meson are in a three-way standoff: Syntax differences require relearning configuration logic for cross-project collaboration (e.g., CMake’s <span>target_link_libraries</span> conflicts with Bazel’s <span>deps</span> rule). Historical baggage hampers modernization: Legacy projects depend on Autotools-generated <span>configure</span> scripts, which have poor compatibility with modern IDEs (like … Read more
