The following schematic overview shows the complexity of building a modern software system with multiple inputs and output artefacts which will help explain why we need to use a build system to manage the process.ĬMake supports several hosted build systems such as GNU Make,(Linux), Visual Studio (Microsoft Windows), Xcode (OSX) and Ninja (multiple platforms) as well as cross-compilation systems such as Android Studio and IAR Workbench. For larger projects this can reduce build times down from tens of minutes or hours, to a few minutes, perhaps even less than one minute. Its purpose is to take your description of a project and generate a set of configuration files to build that project.Īs part of the generation of build configuration files CMake also analyses source code to create a dependency graph of components so that when building the project unnecessary recompilation steps can be omitted to reduce build times. For example, to generate Ninja build files we would use:ĬMake is not a build system like Unix Make but a build system generator.
CMAKE LINUX TUTORIAL GENERATOR
CMAKE LINUX TUTORIAL DRIVER
It is the first of a small series of posts looking at how we build our training projects comprising application code, supporting library code, real-time operating system and bare metal driver code. This blog post is a mix of musings and advice when using CMake for cross-compiling to the STM STM32F407 Discovery board that we use for our embedded C and C++ training. For this reason, we’ve put aside our prejudices and reconsidered the way we build our example projects used during training by replacing scons with CMake. Here at Feabhas, we find ourselves falling in the latter category, despite the fact the CMake is widely used within the embedded and deeply embedded development community.īut we also know that many of the C/C++ static analysis and code quality tools integrate well with the CMake build system.
CMAKE LINUX TUTORIAL HOW TO
In this post we will examine how to use CMake to mange the build process for a cross compilation project.ĬMake can be described as a marmite application: you either love it or hate it.
Then you have to modify the CMake module path so that it can be found.In our previous post Why We Need Build Systems we examined the need for Build Systems in modern software development. In order to use it you have to place it somewhere in your project for instance into a cmake subdirectory. REQUIRED_VARS SDL2_LIBRARY SDL2_INCLUDE_DIR
You can use the following code: cmake_minimum_required (VERSION 3.7 ) project (SDL2Test ) find_package (SDL2 REQUIRED ) include_directories ( $ ) include (FindPackageHandleStandardArgs ) FIND_PACKAGE_HANDLE_STANDARD_ARGS (SDL You need to create a CMakeLists.txt file for your project that includes SDL2 In thisīlog post I will describe the necessary steps to use SDL2 with CMake on both Together with CMake to build a cross platform multimedia application.
SDL2 is the newest version of the Simple Directmedia Layer API.
