how to create makefile for c program in linux

Look for a file named “INSTALL” or “README” in the source code directory of the application for additional configuration parameters and compiling options.

After the installation is complete, we can run the command from anywhere on our system like this:Īnd that’s how we install a package from source code in Linux! Of course you need to be careful as there can be extra steps to perform using the “make” command. These commands can take a bit of time even for simple programs like our “Hello World” example. The last command requires admin privileges, so make sure that you either use it with “sudo”, or that you run it as root to begin with. So first we use a “get” command, and a “tar” command like this: It looks simple, but the source code is surprisingly complex!

In this case, the software simply prints “hello world” onto the screen. It’s free software and is used for demo purposes. For this example, I’m going to make use of a sample “hello world” tar.gz file from gnu.org. The first step is simply downloading the tar.gz file and extracting its contents into a folder – usually of the same name as the tar file itself. Step 1: Getting the tar.gz file and Unzipping it into a Folder In this tutorial, I’ll show you how to do that, as well as how to get rid of program afterwards, if possible. In which case, the author might have created a “tar.gz” file bundled with the source code and it’s up to us to compile and install it on to our system. The only thing you have is the actual source code. Sometimes however, the software doesn’t have a convenient file all ready to install on your particular Linux distribution. It can save you a lot of headaches later on. Due to all these advantages, it’s always recommended to get your software from a recognized repo if you can.

Yum for example, allows you to “undo” individual installations, get rid of packages that are no longer needed, takes care of dependencies etc. These installers make it easy to find, install, and uninstall various packages in a predictable and systematic way. Ubuntu has “apt-get”, CentOS has “yum”, and of course “rpm” is common to all of them (yum is actually just a wrapper around rpm).

Different Linux flavors have their own preferred installers. Most software installation in Linux is done via the inbuilt installers for software that has already been pre-packaged for that particular distribution.
