The installation time will again depend on how big the software is. The make install command is the equivalent of point and click routine on Windows. Look for development versions which end with –devel. However, you can always search software repositories provided by your OS vendor. For the most part, if your OS is new you won’t have any problems.

You might then have to download it from the Web. Say you have a software that depends on GTK+, with the latest version not present. Most of the errors in the compilation process are due to missing or incompatible libraries. If however, there is some problem it prompts you with appropriate status messages. If all is okay, it will display the command prompt. There will be another bunch of messages scrolling across the screen, sometimes with warnings about some resource being absent. This part is going to take a lot of time, depending on the package being compiled as well as the system configuration. The make command is time consuming and results in a whole bunch of messages scrolling across your screen. Binaries are the Unix equivalent of executables, or. The make command uses the Makefile to create installable binaries. This Makefile is then used to build the binary which then needs to be installed. configure command has run-during which you will see a bunch of messages scrolling up the screen in rapid fire sequence-a Makefile will be created. The sample output of a configure command will look something like this:Īfter the. Using -prefix=mydirectory you can change the path where the Makefile will be created. If you know what you are doing you can use -no-create to inspect the output files before they are created. configure command to change the behaviour of the program.įor example, appending -quiet would stop printing the checking… messages during the configure process. Various switches can be used along with the. It basically does a house-keeping job, checking whether all the required resources in the form of system libraries are present and then assigning values for system dependent variables. This command does not change anything substantially. You have to run the command while inside the installed package directory. Some packages might need some additional libraries or might suffer from dependency issues, so it makes sense to know what’s needed.Īfter you have unpacked the tarball and have also solved any dependency issues by installing required libraries it’s time to go to the next step: configuration. Make sure to read the readme, install and other documentation. Change the directory using cd mypackage and then use ls to explore the directory tree. They are compressed using either gzip or bzip2, and hence the different extensions and the slightly differing switches used in the command.Īfter unpacking, a directory will be created with the name of the package in the destination folder. All the source files, associated libraries and documentation are distributed as compressed archives called tarballs. This is the first thing to be done when you download the software. Here is a quick guide to all that you need to know about compiling from source and what goes behind the scenes, without leaving anything to chance.Ĭommand to use: or
However, to most people out there, compiling from source still feels like voodoo. In fact, this is the way source packages were distributed in the old days, and you might still have to go by this route in some cases. Again, you can compile software directly from source code-download the source code which comes in a tarball, unzip it and then compile it. In Linux, Depending on the distribution you have, software can be downloaded in the form of either RPM or Deb packages. In Windows, installing software is a matter of clicks.
