Optimization so that your program runs faster, change the command line See makepp_builtin) you can try it, and if it doesn't workĪutomatically for you, you need to write your own makefile.īy default, for C and C++, makepp compiles the program with debug TheĪctual algorithm is too complicated to discuss here in a tutorial (but It does this by guessing which sourceįiles and libraries you need based on the files that you include.
#CREATE MAKEFILE FOR C PROGRAM HOW TO#
Makepp can sometimes figure out how to compile programs that areĬontained in more than one source file, or programs that must be linked Makepp contains builtin rules for C, C++, and Fortran. These commands don't make any sense to you, see These are the basic commands needed to compile a program on unix. Warning: on unix, to run a program called 'test', you must type Makepp: Entering directory `/somewhere/or/other' For example, suppose you have a program in a single Special, makepp may already know how to build it without your explicitly If your program is relatively simple and doesn't require anything particularly Two modules, then you will definitely want to use a program like makepp. However, if your program consists of even just Makepp, because you know that any change that you make requires If your program consists of a single module, you probably don't need You can do a lot more with makepp than just that if you use your Will assume you are building an executable program from source code, but The processed data files need to be updated whenever some of the dataįiles or analysis programs change. YouĬould, for example, use makepp to do data analysis, where your inputįiles are raw data and analysis programs, and your output files are Makefile to control any kind of procedure where you need to selectivelyĮxecute certain commands depending on which files have changed.
Usually, the input files are program source code, and the output filesĪre executables, but makepp doesn't care what they are. Makefile that contains a detailed recipe for building the program. Its own builtin knowledge (in very simple cases), or on a file called a Standard tool that has been around for many years. It is an improvement on the make program, a Makepp (short for Make-plus-plus, or make++) is a tool for solvingĮxactly this problem. Necessary for determining exactly which modules need recompilation. However, it's too error-prone to allow a human to tell the computer Recompile all modules when only one of them has changed. Used for compiling a program, because it's too time-consuming to However, a straightforward shell script is seldom Another source of examples andĪdvice on writing makefiles for makepp is makepp_cookbook.īuilding a program from its source files can be a complicated and Preferred way to do things with makepp, which is often different from Least peruse the later sections of this file because they show the If you already know a lot about writing makefiles, you might want to at Unix make, but if you're starting from scratch, it is often much simpler to Makepp can accept most makefiles written for the standard
