Installing software from source
All software programs are built from different files. These files are called source
code and are written in programming languages. The most common programming
languages that are used on Linux are C and C++.
There are all sorts of reasons that you may want to download and install a piece
of software that is distributed as source code. Some of these are as follows:
• The software isn't available in the Raspbian repositories.
• The latest version of the software isn't in the Raspbian repositories.
• The features in the software aren't available in the packages in the
Raspbian repositories.
There are a several disadvantages to installing software from source, such as these:
• Updates aren't automatically installed for any software packages that are
installed from source.
• Additional software is required to compile and install the software.
Generally this is the
build-essential
metapackage.
• It can take a long time to compile and install software depending on
its complexity.
If you find a software package that you want to download and install on your
Raspberry Pi, the first thing you need to do is make sure that you have all the
required tools to build the application:
1.
The most common tools can be installed after you have installed the
build-
essential
package:
sudo apt-get install build-essential
This will install all the software tools you need to use to compile
most C and C++ applications, including the make application and
the gcc and g++ compilers.
