If we wish, we can test it now when we feel confident about the program, we can type make install. We now have a compiled version of the program. In effect, we change to the directory where the source was unpacked and do make-the program’s own make file has the necessary information to build the program.
CREATE MAKEFILE FOR C PROGRAM CODE
The source code for the program is compiled. (Many UNIX® program distributions try to work out which version of UNIX® they are being compiled on and which optional UNIX® features are present-this is where they are given the information in the FreeBSD ports scenario). This is to make sure that the source was not corrupted while in transit.Īny changes required to make the source work on FreeBSD are applied-this is known as patching.Īny special configuration needed for the source is done. The checksum for the source is calculated and compared it with one for a known, good, copy of the source.

It is simply a standard library that someone created long ago and made available to other programmers to make their lives easier. Now you understand why you have been including stdio.h in earlier programs.
CREATE MAKEFILE FOR C PROGRAM HOW TO
Read the documentation for your compiler to learn how to use it. If you are not working on a UNIX machine, your compiler almost certainly has functionality equivalent to makefiles. The makefile automatically recompiles everything that needs to be recompiled because of a change. A large program may have several libraries and a main program. It is possible to put multiple lines to be executed below a dependency line - they must all start with a tab. If either of these changes, execute the line gcc -o main main.o util.o to recreate main. The final result of the makefile should always go on line 1, which in this makefile says that the file main is dependent on main.o and util.o. Note that the final executable produced by the whole makefile is main, on line 1 in the makefile. If either of these two files changes, the following executable line(s) should be executed to recreate main.o. For example, main.o: main.c util.h says that the file main.o is dependent on the files main.c and util.h. A dependency line says that some file is dependent on some other set of files. The lines preceded by a tab are executable lines, which can contain any valid UNIX command.
The lines appearing flush left are dependency lines. This makefile contains two types of lines.
