To build Python, we will use make and gcc. • make is a program that is used to read configuration files, usually named Makefile, and check that all requirements to compile the program are met. It is also used to drive the compilation. It is invoked with the configure and make commands. • gcc is the GNU C Compiler, an open-source compiler widely used to build programs. Make sure they are both installed on your system. Under some versions of Linux such as Ubuntu, you can install build tools with the build-essentials package.
