In this comprehensive guide, we will walk you through the process of installing CMake 3.14 on Ubuntu 18.04. CMake is a powerful cross-platform tool that controls the software compilation process using simple platform and compiler-independent configuration files. It generates native makefiles and workspaces that can be used in the compiler environment of your choice.
Before starting, ensure that you have a functioning Ubuntu 18.04 system and have administrative (sudo) privileges.
Method 1: Install from the Ubuntu Repository
This is the easiest method, but it may not install the latest version of CMake.
- Update your system: Always start by updating your system to the latest packages. Run the following command in your terminal:
This command updates the package list and upgrades the installed packages to their latest versions.
sudo apt update && sudo apt upgrade -y
- Install CMake: To install CMake, run the following command:
This command installs CMake from the Ubuntu repository.
sudo apt install cmake
Method 2: Compile from Source
This method is more complex but will ensure you have the latest version of CMake.
- Install necessary packages: You will need to install the build-essential and git packages. Run the following command:
sudo apt install build-essential git
build-essentialpackage includes a range of tools necessary for compiling software, such as gcc and make.
gitis a version control system used to download the CMake source code.
- Download the CMake source code: Use git to clone the CMake repository:
This command downloads the CMake source code and changes the working directory to the CMake directory.
git clone https://github.com/Kitware/CMake/ cd CMake
- Compile and install CMake: Run the following commands to compile and install CMake:
./bootstrap && make && sudo make install
./bootstrapcommand configures the build.
makecompiles the source code, and
sudo make installinstalls the compiled software.
Method 3: Use Conda
If you have conda installed, you can create a new environment and install CMake into it. This method does not require root/sudo privileges.
- Create a new conda environment and install CMake: Run the following command:
This command creates a new conda environment named “CMake” and installs CMake into it.
conda create -n CMake cmake
- Activate the environment: Activate the new environment by running:
This command activates the “CMake” environment.
source activate CMake
In conclusion, these are the three main methods for installing CMake 3.14 on Ubuntu 18.04. Choose the method that best suits your needs. Always make sure to check the official CMake website or the Kitware repository for the most up-to-date version.
Yes, you can use Method 2 (Compile from Source) on other Linux distributions. However, Method 1 (Install from the Ubuntu Repository) may not be applicable as it depends on the distribution’s package manager. Method 3 (Use Conda) is specific to conda environments and may not be directly applicable to other distributions.
To check the version of CMake installed on your system, open a terminal and run the following command:
This command will display the installed CMake version.
Yes, it is possible to have multiple versions of CMake installed on your system. However, you need to be cautious about the paths and ensure that the correct version is used for your projects. Method 3 (Use Conda) allows you to create separate conda environments with different versions of CMake.
If you installed CMake using Method 1 (Install from the Ubuntu Repository), you can uninstall it by running the following command:
sudo apt remove cmake
If you installed CMake using Method 2 (Compile from Source), you can navigate to the CMake source code directory and run the following command to uninstall:
sudo make uninstall
For Method 3 (Use Conda), you can deactivate the environment by running:
This will remove the CMake installation from the conda environment.
If you installed CMake using Method 1 (Install from the Ubuntu Repository), you can upgrade to a newer version by running the following command:
sudo apt update && sudo apt upgrade cmake
This command will update the package list and upgrade CMake to the latest version available in the Ubuntu repository.
If you installed CMake using Method 2 (Compile from Source), you can repeat the steps in Method 2 with the newer version of the CMake source code to upgrade your installation.
For Method 3 (Use Conda), you can update CMake by activating the conda environment and running:
conda update cmake
These methods will ensure that you have the latest version of CMake installed on your system.
