This article mainly introduces what is the use of the prefix command in linux. It is very detailed and has a certain reference value. Friends who are interested must finish it!

Concept:

The installation of source code generally consists of three steps: configure, make, and make install.

Configure is an executable script that has many options. Use the command. / configure-- help to output a detailed list of options under the source path to be installed. Where the-prefix option is the path to configure the installation.

Action 1:

If you do not configure this option, the executable files are placed in / usr/local/bin by default, the library files are placed in / usr/local/lib by default, the configuration files are placed in / usr/local/etc by default, and other resource files are placed in / usr/local/share, which is messy.

If you configure-prefix, such as:

. / configure-- prefix=/usr/lcoal/test

You can put all the resource files in the / user/local/test path without clutter.

Action 2:

When an installed software is no longer needed, simply delete the installation directory and uninstall the software cleanly; migrate the software by simply copying the entire directory to another machine (the same operating system)

Of course, if you uninstall the program, you can also use make uninstall once in the original make directory, but only if the make file has specified uninstall.
