Specify the installation directory when compiling software under Linux

1, the source code installation steps

The installation of the source code generally consists of 3 steps:
1). Configuration (Configure)
2). Compile (make)
3). Install (make install)

2,./configure–prefix=/usr/local/test

Configure is an executable script that has many options for using commands under the source path to be installed./configure–help output A detailed list of options.
Where the –prefix option is the path of the configuration installation, if this option is not configured, after the installation executable file is placed by default in/usr/local/bin, the library file is placed by default in/usr/local/lib, the configuration file is placed by default in/usr/local/etc, and other resource files are placed in /usr/local/share, more messy.
If you configure –prefix, such as:
./configure–prefix=/usr/local/test
All resource files can be placed in the/usr/local/test path without clutter.

3. Prefix options Other benefits

Another benefit of using the-PREFIX option is uninstalling the software or porting the software. When an installed software is no longer needed, simply remove the installation directory, you can uninstall the software cleanly; the porting software simply copies the entire directory to another machine (the same operating system).
Of course, to uninstall the program, you can also use the original make directory once made uninstall, but only if the make file specified uninstall.
