Sometimes, some software may <u>not</u> be available on repositories to install with the '''yum''' command. They may be available from web-pages to download, and compile. Now that you know how to create and decompress "zipped tarball archives", we will demonstrate how to install applications from websites containing these types of archives. Although this method is not as "user-friendly" as using the yum or rpm command, this method is useful if the application is NOT contained in regular software repositories...
In order to build software from source code, you must have the appropriate software development tools (such as make and gcc) and libraries (such as GTK) installed. The required tools will vary depending on the computer languages used in the software being built.

|colspan="2"|{{Admon/note|Using '''&&''' and '''||''' Conditional Statements|A very useful trick when running several commands in sequence is to use conditional statments. The '''&&''' conditional will run the subsequent command only if the previous command returns a true (0) exit status, for example:<br>'''./configure && make'''. The '''||''' conditional will run the subsequent command only if the previous command returns a false (non-zero) exit status, for example:<br>'''./configure || echo "Houston, we have a problem"'''. These conditional can be combined, for example:<br>'''./configure && make || echo "Houston, we have a problem"'''}}
