ConclusionĪt this point, you learn to Install CMake on Ubuntu 20.04. This command will also take some minutes to complete.ĬMake suite maintained and supported by Kitware (/cmake). Here you can install CMake with the following command: sudo make install bootstrapĪfter that build your package with the following command: sudo make Install CMake Latest Version on Ubuntu 20.04 Be sure to install the dependencies mentioned above. Now switch to your CMake directory: cd cmake-3.22.3 Bootstrap ScriptĪt this point, you need to Bootstrap the script.

#Cmake ubuntu 20.04 download#

Then, you need to visit the GitHub CMake Releases Page and get the latest version link and download it with the wget command: wget Įxtract your downloaded file: tar -zxvf cmake-3.22.3.tar.gz If you want to install the latest release of CMake, it’s recommended to download it from the source and build it.įirst, you need to install the dependencies on Ubuntu 20.04 with the following command: sudo apt install build-essential checkinstall zlib1g-dev libssl-dev -y Download CMake 3 on Ubuntu Install CMake on Ubuntu 20.04 from Source When your installation is completed, you can verify your CMake installation by checking its version: cmake -version OutputĬMake suite maintained and supported by Kitware (/cmake ). Then, you can use the command below to install CMake: sudo apt install cmake

#Cmake ubuntu 20.04 update#

First, update your local package index with the following command: sudo apt update -y The first way to install CMake is to use the APT repository. Install CMake on Ubuntu 20.04 from APT Repository To do this, you can follow our article the Initial Server Setup with Ubuntu 20.04. In this guide, you learn to install CMake from the APT repository and from the source on your server.īefore you start to complete this guide, you need to log in to your server as a non-root user with sudo privileges. This prevents cluttering up the source directory and makes it easy to start over again: just remove the build directory and you are done. Any file required for the final build, executables included, will be stored in a separate build directory (usually called build/). This is done by the so-called generators, CMake components responsible for creating the build system files.Īnother nice CMake feature is the so-called out-of-source build. CMake will read the instructions in it and will produce the desired output.

This special text file describes how the project is structured, the list of source files to compile, what CMake should generate out of it, and so on. That’s what the word meta stands for: CMake builds build systems.Ī project based on CMake always contains the CMakeLists.txt file. For example, CMake on Windows will produce a solution for Visual Studio CMake on Linux will produce a Makefile CMake on macOS will produce a project for XCode, and so on. It doesn’t actually build your source code: instead, it generates native project files for the target platform. It takes the name of the executable target and the name of the library target as arguments.CMake is known as a meta-build system. target_link_libraries: This is a CMake command that links a library target to an executable target.It takes the name of the target and a list of source files as arguments. add_library: This is a CMake command that adds a library target to the project.add_executable: This is a CMake command that adds an executable target to the project.CMAKE_INSTALL_PREFIX: This is a CMake variable that specifies the installation directory for the built project.cmake flex g++ gawk gcc gettext git gperf help2man libncurses5-dev libstdc++6. CMAKE_BUILD_TYPE: This is a CMake variable that specifies the type of build to generate, such as Debug or Release. Ubuntu 20.04 LTS or later since the exercises in this chapter were all.It allows you to set project options and generate build files without using the command line. cmake-gui: This is a graphical user interface tool that can be used to configure CMake projects.

#Cmake ubuntu 20.04 code#

Running make in the project directory will compile the source code and create the binary executable.

make: This is a build tool that can be used to build the project after the CMake build files have been generated.

in the project directory will generate the build files in the current directory.

cmake: This is the command-line tool used to configure and generate build files based on the CMakeLists.txt file.

It contains information about the project, such as the source files, dependencies, and build options.

CMakeLists.txt: This is the main configuration file for CMake.

Here are some key concepts and commands related to CMake in Linux: It allows developers to write build scripts in a high-level, platform-independent language and generates build files that can be used with various build tools, such as make, Ninja, and Visual Studio.

#Cmake ubuntu 20.04 generator#

CMake is a popular cross-platform build system and build tool generator that is widely used in Linux environments.
