CMake Version 3 Installation on Ubuntu 14.04

How to install CMake version 3 on Ubuntu using package manager

Recently I’ve been trying to do research on OpenAirInterface using a LimeSDR. Since I’m using their master branch source code, I have to use the old Ubuntu 14.04. For some reasons, I need to test it using the latest LimeSuite source code and compile it myself.

One thing I realized when I did building process for LimeSuite, it throws an error saying that the installed cmake version in the system doesn’t meet the requirements. It needs cmake version 3, but mine was version 2.

At first I thought I need to compile the latest cmake myself, but I decided to Google a little. I found an askubuntu.com thread and turns out, Ubuntu 14.04 already has cmake version 3 package. You just need to install the right package.

So here is what I do.

First remove cmake package from the system.

sudo apt-get remove cmake

Then, instead of installing cmake, use cmake3 package.

sudo apt-get update

sudo apt-get install cmake3

After that, I finally can compile LimeSuite from source code successfully on Ubuntu 14.04. There might be some problems ahead, but it’s a good start to know I don’t need to mess up the OS to use LimeSDR.

Hopefully it can also help you if you face similar problem.
