Ubuntu 16.04 installs a low version of cmake (install cmake installation)

To install a specific version of CMake (e.g. cmake-2.8.9) on Ubuntu 16.04 32-bit without interfering with newer versions of CMake already installed on the system, you may consider the following steps:

1. Download and unzip the CMake compressed file

- First, you need to download CMake from its official website or other reliable sourcescmake-2.8.9-Linux-i386.tar.gzdocument.

https://cmake.org/files/v2.8/

cmake-2.8.9-Linux-i386.tar.gz
  • 1

- Then unzip the file using the following command in the terminal:

tar -zxvf cmake-2.8.9-Linux-i386.tar.gz
  • 1

2. Install to a specific directory

  • After unpacking, you can choose a directory to install this version of CMake, for example/opt/cmake-2.8.9. This will avoid conflicts with other versions of CMake on your system.
    I first useapt purge cmakeUninstall the existing cmake:

  • You can move the unzipped folder to/optTable of contents:

sudo mv cmake-2.8.9-Linux-i386 /opt/cmake-2.8.9

3. Use this version of CMake

  • Once installed, you can run this version of CMake directly by specifying the full path, for example:
/opt/cmake-2.8.9/bin/cmake
  • 1
  • If you need to use this version of CMake frequently, you can.bashrcAdd an alias to the file so that it can be called with a simple command (note: I am calling it as root):
echo 'alias cmake="/opt/cmake-2.8.9/bin/cmake"' >> ~/.bashrc
source ~/.bashrc

This way, every time you entercmake2.8, this specific version of CMake will be called.
