Make install source code installationIf you want to use make installation, then you have to install build-essential this dependency package, after the installation is complete, we can install the source code. The source installation can be broadly divided into three steps: (./configure) –> compilation (sudo make) –> installation (sudo make install).

Configuration: This is the first step in compiling the source code and is done through the ./configure command. Perform this step to prepare the source code for compilation. Common options are -- prefix=prefix to specify where the program is installed. More options are available through Help -- queries. There are also some programs that do not need to perform this step.

Compile: Once configured, you can use make the instructions to execute the source code compilation process immediately. Depending on the specifics of the software, the time required for compiling is different, and all we have to do is to wait patiently and watch it change. Although this step is only a simple instruction, sometimes the problems encountered are very complex. The more frequently encountered scenario is that the program compiles halfway through but does not end satisfactorily. At this point, you need to analyze the error message to find a strategy.

Installation: If the compilation is not a problem, then execution sudo make install can install the program into the system.
