generating a makefile for c program linux

You are building the program using GCC and GNU Make. You wish to rectify this deficiency without having to explicitly specify which headers are used by which source files.

This will correctly rebuild the executable when one of the. c that are located in the same directory, then links them into an executable called hello_world: Suppose you have a makefile which compiles all files with the extension. For these reasons, the use of an automated mechanism for identifying dependencies is highly desirable for all but the simplest of programs. Mistakes can be difficult to diagnose, because they result in a compiled program that does not correspond to the source code. Indicates that the object file main.o depends on the source file main.c and on the header files foo.h and bar.h.Ĭreating these rules manually is both tedious and error-prone. That information is provided by the makefile in the form of rules. In order to do this it needs to know how the source, intermediate and executable files depend on each other. When make builds a program it uses timestamps to determine which files need to be rebuilt and which do not.

To automatically list dependencies between the files in a body of source code, in a form suitable for use within a makefile Background Ubuntu (Lucid, Maverick, Natty, Precise, Trusty)
