What steps should I follow to install CMake version 3.2 on an Ubuntu system?

I’ve been diving into some C++ projects lately, and I keep hearing about how great CMake is for managing builds. However, I’ve hit a bit of a snag because I specifically need to install CMake version 3.2 on my Ubuntu system, and I’m not entirely sure where to start. I know there are different ways to get CMake—like using the package manager or downloading the source files—but honestly, I’m a bit overwhelmed by all the options.

For context, I’m running Ubuntu 20.04, and I’ve seen that the default package manager doesn’t have 3.2 in the repositories. I think it has a newer version, but that’s not what I want. I’ve read a couple of articles that suggest compiling from source, but I feel like that could get tricky; I don’t want to mess something up and end up screwing up my system, you know?

So, if anyone has had a similar experience, can you break down the steps for me? Like, do I need to install any dependencies first? And should I be using Git to clone the source repository, or is there a more straightforward method? Also, any tips on setting up the environment variables afterward would be super helpful, because I’m really trying to avoid going down some dark rabbit hole of errors.

I mean, I wouldn’t mind using a newer version if I absolutely have to, but I’ve come across a few projects that specifically require 3.2, so I want to make sure I’m using the right one. If you’ve managed to install it successfully, could you walk me through your process? Whether you did it with a terminal command or through some other method, I’m all ears. Just trying to wrap my head around what could be the simplest route! Thanks in advance for any guidance you can share!

    1. Installing CMake 3.2 on Ubuntu 20.04

      Installing CMake 3.2 on Ubuntu 20.04

      So, you need to get CMake 3.2 on your Ubuntu 20.04, huh? No worries, I’ve been in the same boat! Here’s a simple way to do it without losing your mind.

      Step 1: Install Dependencies

      Before you dive into compiling CMake from source, you gotta make sure you have some essential build tools installed. Run this in your terminal:

      sudo apt update
sudo apt install build-essential libssl-dev

      Step 2: Download CMake 3.2 Source Files

      Instead of using Git, you can just download the source tarball directly. Here’s how:

      wget https://cmake.org/files/v3.2/cmake-3.2.3.tar.gz
tar -zxvf cmake-3.2.3.tar.gz
cd cmake-3.2.3

      Step 3: Compile and Install

      Now that you’re in the cmake-3.2.3 directory, you can compile it. Run these commands:

      ./bootstrap
make
sudo make install

      Step 4: Verify the Installation

      Once that’s done, you can check if everything went well by running:

      cmake --version

      You should see CMake 3.2.3 or something close to that!

      Environment Variables

      If you need to set up any environment variables (usually not necessary for CMake), you can add to your .bashrc. Just edit that file:

      nano ~/.bashrc

      And add this line at the end (if needed):

      export PATH=/usr/local/bin:$PATH

      Then save and exit, and run source ~/.bashrc to apply the changes.

      Wrapping Up

      And that’s pretty much it! You should be all set with CMake 3.2. Just remember, compiling from source might take a little while, but it’s totally manageable. If you run into any issues, don’t hesitate to search for specific error messages—there’s a ton of help out there!



    2. To install CMake version 3.2 on Ubuntu 20.04, you can follow these steps to compile it from source, which is a straightforward approach that will allow you to get the exact version you need. First, ensure that you have the necessary dependencies installed. Open a terminal and run the following command to install the required tools:

      sudo apt-get install build-essential libssl-dev

      Next, download the CMake 3.2 source files using wget:

      wget https://github.com/Kitware/CMake/releases/download/v3.2.0/cmake-3.2.0.tar.gz

      Once the download is complete, extract the files:

      tar -zxvf cmake-3.2.0.tar.gz

      Navigate into the extracted directory:

      cd cmake-3.2.0

      Now, compile and install CMake with these commands:

      ./bootstrap
      make
      sudo make install

      After the installation is complete, you might want to verify it by running cmake --version to ensure you have the right version installed.

      If you’re concerned about setting up environment variables, typically, this installation will take care of it for you. However, if you run into any issues, you can add the CMake binary path to your PATH variable. To do this, you can edit your ~/.bashrc file and add the line:

      export PATH=/usr/local/bin:$PATH

      Then, run source ~/.bashrc to apply the changes. This setup should have you up and running with CMake 3.2 without braving the pitfalls of package managers or more complex systems!
