Through CMake performance analysis, you can identify the most time-consuming operations when reloading projects and optimize your CMake scripts when necessary. Performance analysis is applicable to CMake version 3.18 and above. CMake stores results in Google’s tracing event format. CLion’s integrated features can help you run traces and visualize the results. Performance analysis is not … Read more
1. Background CMake is a product derived from the development of several toolkits (VTK) by Kitware and some open-source developers, ultimately forming a system and becoming an independent open-source project. Its official website is cmake.org, where you can find more information about CMake. It is a cross-platform build tool that can describe the build process … Read more
This tutorial will guide you step by step in creating and developing a simple CMake project. We will learn the basics of CMake as a build system, as well as the setup and operations of CLion for CMake projects. Note: The example project source code used in this tutorial can be found on GitHub. 1. … Read more
The settings required to build a CMake project are consolidated into a CMake configuration file. It includes the toolchain and build type, as well as CMake options such as generators and environment variables. You can configure multiple configuration files for a project to build targets with different compilers or different settings. To set up a … Read more
Link: https://ukabuer.me/blog/more-modern-cmake/ For C/C++ developers, managing projects often becomes quite tricky when it comes to complex third-party dependencies, especially when cross-platform development is required. CMake, as a cross-platform build process management tool, provides mature solutions for finding and introducing third-party dependencies, creating build systems, testing programs, and installation. By writing a CMakeLists.txt file once and … Read more
1 Overview In our daily development and operations work, we encounter various software packages; software packages can be broadly divided into two categories: binary files, such as (exe, rpm, bin, etc.); the other category is source files (various tarballs). This article will introduce the most commonly used RPM software package in Linux systems, discussing the … Read more
One Background After reading the article “Dynamic Tracing Technology Discussion” (https://blog.openresty.com.cn/cn/dynamic-tracing/), I thought about using SystemTap to trace my own developed kernel module. However, the official documentation of SystemTap (https://sourceware.org/systemtap/documentation.html) only gives examples of tracing kernel modules by using drivers from the kernel source tree, for example: probe module(“ext3”).function(“*”) { }, and indeed, the verification … Read more
